Resolution Copper Mining Method
 
03:02
Resolution Copper will use the panel caving mining method, a variation of block caving to break up the underground ore. This technique uses gravity primarily to break the rock. Panel caving is more efficient than other underground mining methods for this type of deposit. It will result in lower operating costs and will allow us to mine the most ore while creating the least amount of waste. The technique is also favorable because it is safe, allows a high degree of mechanization, and results in both high production rates and favorable economies of scale. Help us secure Arizona's future.

Copper mines in Zambia - Straight through Africa
 
43:29
Trade is better than aid for Africa. They say. In a journey through copper thieves and mine barons in the north of Zambia, Bram Vermeulen investigates the truth behind that slogan. From a distance they look like ants, the hundreds of men digging holes in the rubble slopes of an old copper mine in Zambia. They are looking for copper ore in the walls of the enormous pit, without wearing helmets and without reinforcing the walls of their caves. Life-threatening, of course. But they find enough to live on. Is it legal, Bram asks. They laugh about it. No of course not. But the Chinese buyer does not really ask where they get their ore from. You just have to leave when the guards of the mine come. How different is it in a huge copper mine in full operation. Huge machines drive off and on. Sirens sound regularly, followed by explosions. Here, 300,000 tons of stone are moved every day, and the copper ore from it yields a profit of hundreds of millions of dollars a year. But it is a foreign company that raises that money. And if the productivity gets too low after about twenty years, the investors will move on. From the air it is easy to see how far-reaching it all is. The mine takes big chores out of the country and turns huge plains into a kind of lunar landscape. But other changes are also visible. Houses, schools, a golf course. Prosperity, therefore, emphasizes a mine boss. Seven years ago this was still a dull provincial town, and now look! A little further on the big changes are about to begin. There is a giant copper mine here, and for that an area of ​​no less than four hundred square kilometers is expropriated. The new owners promise economic prosperity. Did not a city like Johannesburg also start out as a simple mine? Naturally, people living in the area can not stay. They have worked the land for generations, but they can not show ownership documents. They have not been asked anything. They do get compensation for their houses, chickens and fruit trees, but not for the ground. "Everything under the ground is state property," says a representative of the mining company, "and that is what the state can rent out to us." Residents who do not want to leave are squatters who violate the law from that moment on. Even though they were born and lived there all their lives. Those former residents are moved to neat new houses outside the area. With toilet, and bigger than the previous house, but without land to grow food. Some of them seem satisfied with that. Most do not. 'In Africa, land has sentimental value. You are no one without land, 'says one of them. "So you're destroying these people. They will not pass on anything to the next generation. " Episode 6. Copper fever  For Africa, trade is better than aid, or so they say. On a journey to copper thieves and mine bosses, Bram Vermeulen investigates the truth behind the slogan.

PROCESSING COPPER ORE IN  KITWE ZAMBIA
 
07:40
Mopani Copper Mines Mopani Copper Mines Plc (Mopani) is a joint venture company based in Kitwe as 95% of its operations are located there, comprising Glencore International AG (73.1%), First Quantum Minerals Ltd. (16.9%) and Zambian Consolidated Copper Mines Limited (10%). Mopani operates the Mufulira mine, smelter, concentrator and copper refinery and the Nkana mine, concentrator and cobalt plant. MCM produced 134,800 tons of copper and 2,040 tons of cobalt in 2003. MCM is investing in a number of oxide copper projects at several of its properties, including an in-situ leaching project at Mufulira and heap leaching at Nkana, and has achieved significant production increases at its underground mining operations in Kitwe and Mufulira. Copper production from internal sources was supplemented by the purchase of some 18,000 tons of copper in high-grade oxide concentrate bought from the Democratic Republic of the Congo. Nkana Mine Nkana mine is one of the largest in Africa, a copper mine located 1 km south-west of Kitwe. The mine is underground as well as open pit and is in operation since 1932 and has produced 6,000,000 tons of copper so far. Its reserves underground include 69,000,000 tons of grading, 16,000,000 tons of copper, and 98,000 tons of cobalt. Its resources include 126,000,000 tons of grading, 43,000,000 tons of copper, and 300,000 tons of cobalt. Copper and cobalt mineralisation occur within the ore shale. Copper mineralisation in the deposits changes from mostly chalcopyrite in the South Orebody, to chalcopyrite-bornite in the Central area and to bornite-chalcopyrite at Mindola. Cobalt occurs as carrollite and cobaltiferous pyrite in approximately equal proportions. The mine produces copper and cobalt from three sources: Mindola Shaft, Central Shaft and South Orebody Shaft. Vertical crater retreat is the predominant mining method while sublevel open-stopping and sublevel caving methods are also used. Other metallurgical facilities, under a management contract by an affiliate of the Anglo American Group, include the Nkana smelter (not owned by Mopani), acid plant (not owned by Mopani) and copper refinery (not owned by Mopani). There is extensive mine tailings around this mine. Nkana Concentrator Nkana Concentrator of Mopani mines, located in Kitwe, treats copper-cobalt sulphide ore using a bulk flotation and segregation flotation flowsheet to produce separate copper and cobalt concentrates. Nkana Concentrator is the most important mineral processing unit of Mopani, as it contributes about 65% of cobalt concentrates treated at the Nkana and Chambeshi Cobalt plants to produce high purity cobalt metal. Konkola Copper Mine Konkola Copper Mine (KCM) is the largest copper mining company in the country. Although based in Chingola, 15% of its operations—namely Nkana Refinery, Nkana Acid Plants and Nkana Smelter (the largest smelter in the nation) -- are located in Kitwe. The Nkana Smelter is the largest primary copper production plant in Zambia. The plant treats concentrates mainly from Nkana, Nchanga, and Konkola mines, which are wholly owned by KCM to produce up to 150,000 tons of new copper. Nkana Smelter The smelter produces high grade anodes, which are electrolytically refined. Sulphur dioxide gas produced by the converters is converted into sulphuric acid which is then used at the Tailings Leach Plant in Nchanga for recovering oxide copper. The smelter also produces discard slag from the reverbs that is rich in cobalt which is stored for future reclamation. This smelter was part of the Konkola Copper Mine's operation at privatisation and has subsequently closed. Nkana Refinery The Nkana Copper Refinery produces electrolytically refined copper in the form of cathodes. The copper meets the LME premium quality grade. The tankhouse has a capacity of about 180,000 tons of finished copper per annum. Nkana Acid Plants There are two single contact sulphuric acid plants at Smelterco, namely the No.3 and No.4 plants. No.3, the largest, is still operational. The plant has a design capacity of 1,050 tons of acid per day. FROM http://en.wikipedia.org/wiki/Mining_in_Zambia

Underground Training Systems - Introduction to Underground Mining
 
02:59
Underground Training Systems (UTS) has been set up to offer courses in hardrock underground mining (Gold, Nickel, Copper, Diamonds and many other base metals, excluding coal). Each course has been developed using our company Core Values and Positive Tips for Safety in a Hazardous Workplace . All courses are presented by a consultant that has a W.A shift boss ticket and more than 15 years practical underground mining experience. This gives the course participants a unique opportunity to ask questions and receive experienced answers about all different aspects of mining life. The jobs are Australia wide and there are roughly 23,000 hard rock miners within the Australian industry. The W.A. the Mines Department has estimated that between 10%-15% of these workers leave the industry every year. That works out to be 2300 to 3450 people that leave the industry every year (for a number of reasons) that need to be replaced. These entry level positions are filled with new starters that are commonly referred to as Green . This is where UTS Introduction to Underground Mining course has given employers the opportunity to employ people that have the knowledge of how an underground mine works and the entry level skills that they will be required to be performed. This allows a UTS graduate to become a useful member of an underground crew in 4-7 days of being on site. Entry level jobs covered include dump truck operator, nipper, drillers offsider and service crew member . By completing Introduction to Underground Mining over three days you will have the knowledge for us to present your resume to the relevant mining companies for entry level positions as part of our Placement Program . This program has been designed to give you the best possible chance to "get your foot in the door" and helpful staff who will start the employment process once you enrol.

Originally a public domain film, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). https://en.wikipedia.org/wiki/Copper_extraction_techniques Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ Copper extraction techniques refers to the methods for obtaining copper from its ores. The conversion of copper consists of a series of chemical, physical, and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be beneficiated (concentrated). To do this, the ore is crushed. Then it must be roasted to convert sulfides to oxides, which are smelted to produce matte. Finally, it undergoes various refining processes, the final one being electrolysis. For economic and environmental reasons, many of the byproducts of extraction are reclaimed. Sulfur dioxide gas, for example, is captured and turned into sulfuric acid — which is then used in the extraction process... History The earliest evidence of cold-hammering of native copper comes from the excavation at Çaÿonü Tepesi in eastern Anatolia. The radiocarbon date is 7250 ± 250 BCE. Among the various items considered to be votive or amulets there was one that looked like a fishhook and one like an awl. An archaeological site in southeastern Europe (Serbia) contains the oldest securely dated evidence of copper making at high temperature, from 7,000 years ago. The find in June 2010 extends the known record of copper smelting by about 500 years, and suggests that copper smelting may have been invented in separate parts of Asia and Europe at that time rather than spreading from a single source. Copper smelting technology gave rise to the Copper Age and then the Bronze Age. Concentration Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals (including copper) being less than 2% of the total volume of the ore rock. A key objective in the metallurgical treatment of any ore is the separation of ore minerals from gangue minerals within the rock. The first stage of any process within a metallurgical treatment circuit is accurate grinding or comminution, where the rock is crushed to produce small particles... Subsequent steps depend on the nature of the ore containing the copper. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant. For sulfide ores, both secondary (supergene) and primary (hypogene), froth flotation is used to physically separate ore from gangue. For special native copper bearing ore bodies or sections of ore bodies rich in supergene native copper, this mineral can be recovered by a simple gravity circuit... Until the latter half of the 20th century, smelting sulfide ores was almost the sole means of producing copper metal from mined ores (primary copper production)... The copper is refined by electrolysis. The anodes cast from processed blister copper are placed into an aqueous solution of 3–4% copper sulfate and 10–16% sulfuric acid. Cathodes are thin rolled sheets of highly pure copper or, more commonly these days, reusable stainless steel starting sheets (as in the IsaKidd process). A potential of only 0.2–0.4 volts is required for the process to commence. At the anode, copper and less noble metals dissolve. More noble metals such as silver, gold, selenium, and tellurium settle to the bottom of the cell as anode slime, which forms a salable byproduct. Copper(II) ions migrate through the electrolyte to the cathode. At the cathode, copper metal plates out, but less noble constituents such as arsenic and zinc remain in solution unless a higher voltage is used. The reactions are: At the anode: Cu(s) → Cu2+(aq) + 2e− At the cathode: Cu2+(aq) + 2e− → Cu(s)...

NOTE: Although this video shows an up-close look at the blasting process, NEVER go near an active surface mine or blast site without Federal training and permission. FYI, the white bags are Emulsified Ammonium Nitrate. The read cap is TNT and the silver rod that is connected to it by the yellow wire is the blasting cap, it's what ignites the shot. The white pebbles that are emptied into the blast holes by the powder trucks are the main explosive- "ANFO" or Ammonium Nitrate, which is a mixture of fertilizer and diesel fuel. Once the holes are filled with explosives, rock fines or "stemming" is pushed back in the holes and packed down to keep the explosives under pressure. After all the holes are loaded and rigged up, it's time for the fireworks! And remember kids, don't try this at home! Want to see more Blasting?

Finding Something Unexpected in an Abandoned Copper Mine
 
14:48
What an unexpected discovery! Paul and I never imagined finding what we found deep in this abandoned copper mine in Arizona. The Warren-Bisbee Mine's obscure entrance was basically a rabbit hole and didn't look too promising. However, once we gained entry by sliding in on our backs, the tunnels opened up and were surprisingly extensive. One tunnel led us deep into the mine to an inner area where we found -- something. Something impressive. Something rare that I've only seen a few times in abandoned mines over the last seven years or so. And it's all here in this video. Enjoy! Don't forget: New videos are released at midnight (Pacific Time) on the 1st, 10th, and 20th of each month. View and use the information in my videos at your own risk. All abandoned mines (especially the ones in my videos) are very dangerous and should not be entered under any circumstances. No potentially life-threatening, dangerous, or legal decisions and assumptions should be made based on information in my videos.

It is a ductile metal with very high thermal and electrical conductivity. Pure copper is soft and malleable; an exposed surface has a reddish-orange tarnish. It is used as a conductor of heat and electricity, a building material, and a constituent of various metal alloys. The metal and its alloys have been used for thousands of years. In the Roman era, copper was principally mined on Cyprus, hence the origin of the name of the metal as сyprium (metal of Cyprus), later shortened to сuprum. Its compounds are commonly encountered as copper(II) salts, which often impart blue or green colors to minerals such as turquoise and have been widely used historically as pigments. Architectural structures built with copper corrode to give green verdigris (or patina). Decorative art prominently features copper, both by itself and as part of pigments. Copper(II) ions are water-soluble, where they function at low concentration as bacteriostatic substances, fungicides, and wood preservatives. In sufficient amounts, they are poisonous to higher organisms; at lower concentrations it is an essential trace nutrient to all higher plant and animal life. The main areas where copper is found in animals are tissues, liver, muscle and bone. Copper, silver and gold are in group 11 of the periodic table, and they share certain attributes: they have one s-orbital electron on top of a filled d-electron shell and are characterized by high ductility and electrical conductivity. The filled d-shells in these elements do not contribute much to the interatomic interactions, which are dominated by the s-electrons through metallic bonds. Contrary to metals with incomplete d-shells, metallic bonds in copper are lacking a covalent character and are relatively weak. This explains the low hardness and high ductility of single crystals of copper. At the macroscopic scale, introduction of extended defects to the crystal lattice, such as grain boundaries, hinders flow of the material under applied stress thereby increasing its hardness. For this reason, copper is usually supplied in a fine-grained polycrystalline form, which has greater strength than monocrystalline forms. The low hardness of copper partly explains its high electrical (59.6×106 S/m) and thus also high thermal conductivity, which are the second highest among pure metals at room temperature.[4] This is because the resistivity to electron transport in metals at room temperature mostly originates from scattering of electrons on thermal vibrations of the lattice, which are relatively weak for a soft metal.[2] The maximum permissible current density of copper in open air is approximately 3.1×106 A/m2 of cross-sectional area, above which it begins to heat excessively. As with other metals, if copper is placed against another metal, galvanic corrosion will occur. Together with osmium (bluish), and gold (yellow), copper is one of only three elemental metals with a natural color other than gray or silver. Pure copper is orange-red and acquires a reddish tarnish when exposed to air. The characteristic color of copper results from the electronic transitions between the filled 3d and half-empty 4s atomic shells... Most copper is mined or extracted as copper sulfides from large open pit mines in porphyry copper deposits that contain 0.4 to 1.0% copper. Examples include Chuquicamata in Chile, Bingham Canyon Mine in Utah, United States and El Chino Mine in New Mexico, United States. According to the British Geological Survey, in 2005, Chile was the top mine producer of copper with at least one-third world share followed by the United States, Indonesia and Peru. The amount of copper in use is increasing and the quantity available is barely sufficient to allow all countries to reach developed world levels of usage.

11 Most Massive Mines in the World
 
10:20
From the worlds largest gold mine found on the top of a mountain to the largest diamond mine in the world here are the most massive mines in the world! Subscribe to American EYE! 5.. Asbestos Mine, Canada Also known as the Jeffrey Mine, it’s located in Asbestos, Quebec and it was in operation until 2012. It’s a whopping 2 kilometers wide and 370 meters deep! Check out this thing on google maps and you can tell how completely massive this thing is! It’s the by far the largest asbestos mine in the world. For a long period of time, people would use this mineral to put into their walls and keep their homes from catching on fire! But recently there’s been a link with asbestos and a disease called mesothelioma, which is a lung condition. This is a toxic substance that people should avoid, so obviously this large mine went out of business. The lake at the bottom might look like an inviting blue, but you can bet your bottom dollar, it’s highly toxic! The small town that grew with the thriving asbestos industry feels like they’ve kind of lost their identity once the mine was forced to close, but people do still live there. 4. Mcarthur River Uranium Mine In case you were wondering which mine produces the most uranium in the world, that would be of course the Mcarthur River uranium mine in Saskatchewan Canada. This huge deposit was found in 1988 and finally a mining operation took place in 1997, when it began producing what’s known as Yellowcake. It’s not the kind of yellow cake you’d eat with your grandparents. This stuff has a horrific odor and basically what it is, is concentrated uranium powder which can then be used for powering nuclear reactors. We imagine this powdery substance is quite difficult to get ahold of. There aren’t a ton of photos of this place but, it does produce about 13 percent of the global uranium production across the globe. 3. Diavik Diamond Mine In case you thought it was Africa who had all the massive diamond mines, think again! The Diavik Diamond mine, found in the the northwest territories of Canada is one of the largest producers of diamonds in the Northern hemisphere and this place is pretty crazy! They annually produce 7 million carats of diamonds each year and you better believe it’s not easy to get here. The Diavik mine is found north of the arctic circle and it’s definitely cold! This photo here shows the subarctic landscapes that surround the diamond mine. You thought getting to work in the morning was tough for you? Imagine trying to get to work here! Just recently in 2015, this diamond produced what was known as the Diavik Foxfire 187.7 which is one of the largest rough gem quality diamonds ever produced. 2. Siberian Diamond Mine Also known as the Mirny Mine, The USSR began searching for ways to make to make themselves a more economical stable and independent union. In 1955 the Soviets discovered large diamond deposits at this site in the far away lands of Siberia and many people got to work very quickly in order to help bring wealth to the union. After about 20 years of operations, they finally decided that At one point this mine produced 10 million carats of diamonds a year and reaches a max depth of 524 meters or around 1700 feet making it the 2nd largest excavated hole in the world. The mine is so deep, airspace is closed over the hole due to helicopter crashes caused from the downward flow of air. The construction of this in the frigid conditions of Siberia must have been grueling and downright cruel. Sources state that the machinery used at this mine had to be covered at night or it would freeze Are the diamonds worth freezing to death?! It’s unoperational today but Some claim that there’s still a bunch of diamonds in this mine and the whole thing could be worth about 12 Billion dollars. It’s possible that controlling this diamond is mine is crucial to controlling the price of diamonds across the world. Bingham Copper Mine The bingham copper mine located near Salt Lake City Utah is home to the biggest pit in the world and it’s been in operation since 1903. It’s about 2.5 miles wide and if it were a stadium, it would be able to fit an estimated 9.5 million people. It keeps getting bigger and bigger too! Diligent workers can move about 250,000 tons of rock each day and it’s even become a tourist attraction in recent years before a massive landslide took place. Some claim that this was the biggest non volcanic landslide to take place in North American modern history. This photo we see here shows you the aftermath of this massive landslide and Bingham Copper mine and it makes you wonder how safe some of the conditions at these mines truly are. The landslides were so massive, that they actually triggered a few small earthquakes! Experts estimated that 165 tons of earth slide down from the top of the mine all the way to the bottom.

How Lead is Mined & Refined: "A Story Of Lead" 1948 US Bureau of Mines; Lead Metal Mining & Refining

Originally a public domain film from the US National Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and mild video noise reduction applied. The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original). https://en.wikipedia.org/wiki/Lead Wikipedia license: http://creativecommons.org/licenses/by-sa/3.0/ Lead has been commonly used for thousands of years because it is widespread, easy to extract and easy to work with. It is highly malleable as well as easy to smelt. Metallic lead beads dating back to 6400 BCE have been found in Çatalhöyük in modern-day Turkey. In the early Bronze Age, lead was used with antimony and arsenic. The largest preindustrial producer of lead was the Roman economy, with an estimated annual output of 80,000 tonnes, which was typically won as a by-product of extensive silver smelting. Roman mining activities occurred in Central Europe, Roman Britain, the Balkans, Greece, Asia Minor and Hispania which alone accounted for 40% of world production. Roman lead pipes often bore the insignia of Roman emperors (see Roman lead pipe inscriptions). Lead plumbing in the Latin West may have been continued beyond the age of Theoderic the Great into the medieval period. Many Roman "pigs" (ingots) of lead figure in Derbyshire lead mining history and in the history of the industry in other English centers. The Romans also used lead in molten form to secure iron pins that held together large limestone blocks in certain monumental buildings. In alchemy, lead was thought to be the oldest metal and was associated with the planet Saturn. Alchemists accordingly used Saturn's symbol (the scythe, ♄) to refer to lead. Up to the 17th century, tin was often not distinguished from lead: lead was called plumbum nigrum (literally, "black lead"), while tin was called plumbum candidum (literally, "bright lead")... Most ores contain less than 10% lead, and ores containing as little as 3% lead can be economically exploited. Ores are crushed and concentrated by froth flotation typically to 70% or more. Sulfide ores are roasted, producing primarily lead oxide and a mixture of sulfates and silicates of lead and other metals contained in the ore. Lead oxide from the roasting process is reduced in a coke-fired blast furnace to the metal. Additional layers separate in the process and float to the top of the metallic lead. These are slag (silicates containing 1.5% lead), matte (sulfides containing 15% lead), and speiss (arsenides of iron and copper). These wastes contain concentrations of copper, zinc, cadmium, and bismuth that can be recovered economically, as can their content of unreduced lead. Metallic lead that results from the roasting and blast furnace processes still contains significant contaminants of arsenic, antimony, bismuth, zinc, copper, silver, and gold. The melt is treated in a reverberatory furnace with air, steam, and sulfur, which oxidizes the contaminants except silver, gold, and bismuth. The oxidized contaminants are removed by drossing, where they float to the top and are skimmed off. Since lead ores contain significant concentrations of silver, the smelted metal also is commonly contaminated with silver. Metallic silver as well as gold is removed and recovered economically by means of the Parkes process. Desilvered lead is freed of bismuth according to the Betterton-Kroll process by treating it with metallic calcium and magnesium, which forms a bismuth dross that can be skimmed off. Very pure lead can be obtained by processing smelted lead electrolytically by means of the Betts process. The process uses anodes of impure lead and cathodes of pure lead in an electrolyte of silica fluoride...

Restoring a Former Copper Mine in Nevada
 
02:18
Tetra Tech implemented a design-build remediation project for an underground copper mine at the former Rio Tinto Mine in northwest Nevada. The 280-acre Rio Tinto Mine operated from 1932 to 1947, milling low grade ore on-site. Tailings from the milling process were placed in the lower Mill Creek Valley, and half of the tailings were completely saturated with water, which caused downstream migration of contaminants. Tetra Tech transported contaminated mine tailings to a constructed, on-site long-term storage repository. The team excavated soil from a nearby hillside for the repository. The soil was stockpiled for beneficial reuse as backfill in the tailings pond and construction of the evapotranspirative cover on the repository. This cover includes a series of constructed stormwater terrace channels, which intersect and convey the runoff from the slopes to two perimeter channels or spillways. Tetra Tech worked to restore the previous mine site to its natural condition before mining activities. The team also restored Mill Creek to facilitate fish passage with the use of fish resting pools and sections of stream riffles. Over the life of the project, Tetra Tech removed and treated approximately 600,00 cubic yards of tailings, treated 2 million gallons of contaminated mine water, and restored 2,200 feet of Mill Creek with the capability to facilitate fish passage.

Global commodity prices have fallen over the past few months. The price of copper has taken a hit because of a slump in demand from China. China consumes 50% of the world's supply of the metal, and that has had a ripple effect in countries like Zambia, which is Africa's second biggest producer. Al Jazeera's Fahmida Miller explains.
