Uranium ore can also be recovered by the in-situ recovery (ISR) method, given appropriate geological conditions. The ISR method is applicable only to sandstone-hosted uranium deposits located below the water table in a confined aquifer. ISR is a method that leaves the uranium orebody in the ground. The uranium is dissolved in either sulfuric acid or a mildly alkaline solution that is injected into and recovered from the aquifer by means of wells. The uranium-bearing solution is then pumped back up to the surface, leaving the rock undisturbed. Nearly a quarter of the uranium mines use the ISR method. 3d animation by www.mininganimations.com

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re-separates them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas in situ mining lacks these liners and pulls pregnant solution up to obtain the minerals. Most mining companies, favor the economic feasibility of the heap leaching, considering that heap leaching is a better alternative to conventional processing (such as flotation, agitation, and vat leaching). Additionally, dump leaching is an essential part of most copper mining operations and along with other deterministic factors, determines the quality grade of the produced material. Due to the effect that the dump leaching has, i.e. it can contribute substantially to the economic viability of the mining process it is advantageous to include the results of the leaching operation in the economic overall project evaluation. This, in effect, requires that the key controllable variables, which have an effect on the recovery of the metal and the quality of solution coming from a dump leaching process. The process has ancient origins; one of the classical methods for the manufacture of copperas (iron sulfate) was to heap up iron pyrite and collect the leachate from the heap, which was then boiled with iron to produce iron(II) sulfate

How Uranium is mined | World biggest Uranium mines | How Uranium mining works
 
02:46
Uranium is a natural element with an average concentration of 2.8 parts per million on the Earth’s crust. It is more abundant than gold, silver or mercury, approximately the same as tin as and slightly less abundant than cobalt or lead. More than half of the world's uranium production comes from Australia, Canada, or Kazakhstan. Kazakhstan is, by far, the largest producer of uranium, approximately about 40 percent of global production. It should not be surprising, then, that five of the ten biggest uranium mines are located in the Central Asian country. Olympic Dam mine, Australia: Olympic Dam mine is a large poly-metallic underground mine located in South Australia. It is the second largest uranium-producing mine in the world. Appx 70% of the mine's revenue comes from copper, 25% from uranium, and the remainder from silver and gold. The Olympic Dam mine uses 35 million litres of Great Artesian Basin water each day, making it the largest industrial user of underground water in the southern hemisphere. McArthur River Uranium Mine: McArthur River Uranium Mine in Canada, is the world's largest high-grade uranium deposit. Production at McArthur River began in 1999 and the mine has an average ore grade of nearly 11% triuranium octoxide over 100 times the world average. Arlit Uranium. Mine, Niger: Arlit mine is a large mine located near Arlit, in the northern part of Niger. Uranium is extracted from the sedimentary deposit at depths of 50 to 70 meters and heap leached on site, at the open-pit mine. Ranger Uranium Mine: Ranger Uranium Mine is a mine in the Northern Territory of Australia. It is operated by Energy Resources of Australia, a 68% subsidiary of Rio Tinto Group. Uranium mined at Ranger is sold for use in nuclear power stations in Asia, Europe and North America. Ranger Uranium Mine is the open-pit mine produced 3216tU, approximately 6% of the world total. Langer Heinrich mine: Langer Heinrich mine is a large open pit mine located in the western part of Namibia Desert. Uranium is found within carnotite, an oxide that contains uranium and vanadium. The mine produces up to 1,180t of uranium oxide concentrate from 1.5Mt of calcrete-hosted ores per year. Krasnokamensk Uranium Mine, Russia: The Priargunsky mine is a large open pit mine located near the town of Krasnokamensk in the southern part of Russia. Priargunsky mine, delivered 3 percent of the world’s total uranium output. South Inkai Uranium Mine, Kazakhstan: South Inkai mine is a large in-situ leaching mine located in the southern part of Kazakhstan. It is one of the largest uranium reserves in Kazakhstan having estimated reserves of 135.4 million tonnes of ore grading 0.026% uranium. Budenovskoye 2 Uranium Mine, Kazakhstan: Budenovskoye 2 Uranium Mine, Kazakhstan having estimated reserves of 40.7 million tonnes of ore grading 0.022% uranium Rossing Uranium Mine: Rossing Uranium Mine in Namibia is the longest-running and one of the largest open pit uranium mines in the world. Mine produced 3,711 tonnes of uranium oxide, becoming the fifth-largest uranium mine with 8 per cent of global output.

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

Hull-Rust-Mahoning Ore Mine Blast on June 28, 2016
 
13:51
(Hibbing, MN) I recorded this mine blast shortly after 11:00AM on Tuesday, June 28, 2016 at the massive Hull-Rust-Mahoning open pit (largest open ore pit in the world). The actual explosion is at the 11-minute mark, however the discussions of former pit employees prior to that offer insight into the area. Roughly 25% of the iron used by the US in WWII came from this mine. The mine will continue to expand for the next 50-80 years. The location from which this video was shot will soon be mined for ore. About this blast...Hibbing Taconite fires a blast to break the ore and rock. The blast holes are 16 inches in diameter and 45 feet deep. The ore is refined on location and then the higher grade is transported via rail to Superior and loaded into 1000-foot ore freighters or train cars. When this pit is no longer mined, it will become a 500-foot deep lake as it is naturally water fed. In fact, water is pumped out of the pit at a rate of 18,000 gallons per minute. This is equivalent to a dozen city fire engines pumping non-stop at full capacity. A retired 20-foot-tall haul truck (170 ton payload capacity) and numerous other vintage mining equipment are on display. A friendly gift shop / museum is also on site. There is not a fee to visit this site and it would be interesting to both adults and children. Kids can climb special steps in order to sit in the driver's seat of the huge haul truck - bring the camera! Also, experience the "vanished" town of early Hibbing as sidewalks, street signs and foundations are all that remain after Hibbing was re-located further away from the mine about 100 years ago. ...Eerie feeling to stroll the still intact sidewalks of the lost town and to ascend steps that once led to schools, city buildings and mining offices.

SAUDI ARABIA GOLD MINE! GOLD MINES LIST OF MODERN SAUDI ARABIA, GOLD PROJECT AND PRODUCTION IN SAUDI
 
06:38
Gold has been used for coinage, jewelry and adornments throughout recorded history. Goldsmithery is one of the oldest trades that displayed man’s artistic creativity. It can be traced back to the time of the pharaohs of Egypt. Gold was first mined in Arabia approximately 3000 BC. A second period of activity was during the Islamic Abbasid period between 750 and 1258 AD. Saudi Arabia is the World's largest gold Producer country. Saudi Arabia economy depend its oil and gold production. Besides The Kaaba sharif also located in Mecca major city of Saudi Arabia. ALLAH IS THE MOST MARCEFULL & GRATEST. Allah give many natural sources for wealth in Saudi Arabia. There are many gold mine in Saudi Arabia. Extraction of gold started in the Kingdom during the era of King Abdulaziz, particularly between 1939 and 1954, at Mahd Al-Dhahab after the deposit was rediscovered in 1932. Ma'aden Gold and Base Metals Company (MGBM), a wholly owned subsidiary of Ma'aden, undertakes the development and operation of gold and base metals. Al-Duwaihi is the largest gold mine in Saudi Arabia, located at Al-Khurma province. The mine accounts for more than half of Saudi Arabia's gold productions. Saudi Arabia's mining company Ma'aden invested more than $400 million (1.5 billion riyals) in its construction, infrastructure and facilities. Another Mahd Al-Dhahab was the first gold mine in the modern Saudi Arabia. In 2007, Mahd Al-Dhahab mined and processed approximately 183,425 tons of ore at a grade of 11.1 grams per ton of gold from underground operations, resulting in gold production of approximately 58,256 ounces. The mine also processes reclaimed tailings and produces copper and zinc concentrates for third party toll smelting. Bulghah mine is located in the Al Madinah Province, about 65 kilometers south of the Sukhaybarat metallurgical processing plant. It comprises an open pit mine, which mines lower grade ore (less than 1.0 gram per tonne of gold) for processing at the Bulghah heap leach processing facility. Higher-grade ore of more than (1.0) gram per tonne of gold is transported for processing at Sukhaybarat.

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

Mineral-munching microbes

A visit to the bare white hills of tailings from a mine site inspired Dr Miao Chen to think about environmentally friendly ways of extracting metals from ores. She works with naturally occurring micro-organisms which digest mineral ores, leaching metals in a process which saves water and energy. She and her team have also developed solid-state sensors for use in streamlining mining processes, and also for environmental monitoring. This research was carried out as part of the Office of the Chief Executive (OCE) Science Leader program.
