The Mining Minors
 
06:03
Kenyan law prohibits children from working, yet the government has done little to enforce this prohibition particularly in mines where child labour is exploited. Government officials rarely inspect many of the small-scale mines that use such minors and at times even sanction those which hire the vulnerable children. In our special feature "the mining minors", our reporter, Sally Mbilu, spotlights the gold mines in Nyatike, Migori County where children as young as eight years old are working in the small-scale gold mines, with grave risks to their health and lives.

Siderite Vs Sandstone
 
02:35
We are working on the theory (based on the current evidence) that the primary source of iron ore used in our bloomery furnace was iron rich sandstone NOT Siderite (as generally agreed by academics). All we are saying is that we don't find ANY fragments of Siderite on-site but plenty of roasted (magnetic ) sandstone. Close by are at least two areas that clearly show the 'roasting' of large amounts of sandstone. If proved then this would mean our ancestors overcame the problem of a high silica content (which effects the formation of slag) and could still produce iron from sandstone!

Assessing the latest in Steam Winding Engine technology for Greenlaws Mine
 
02:46
Ian and Peter go to inspect an old mine that's being closed and the winding engine sold off. Will the engine fit at the top of the shaft, and where will the Lancashire Boilers be installed? Can we get 800 foot of rope onto the drum? Can we employ the old Victorian winder driver with his bowler hat...?

Mine Hoist in Motion.wmv
 
03:02
This is a personnel and equipment hoist that I designed for a coal mine in West Virginia. The hoist is 40,000 pound rope pull at at 500 feet a minute. There are two seperate spring applied brakes. Normal stopping and starting is very smooth and repeatable. I believe several safety features are unique to my design. The hoist will automatically take up slack if the magnetic brake car stops on the slope. There is a quick acting slack rope switch. A torque slip clutch protects against an overhauling shock load, and is rated 4x normal torque, while the yield strength of all the mechanical components is 7x normal full load torque.

A spectacular cavity is washed out in Greenlaws East Flats - greenish yellow crystals line a mud filled hole that just gets bigger as we wash. Neill hasn't collected underground before and he's in seventh heaven. It's named the Michael James pocket, after the 6 month old grandson of mine owner, Mike Pattinson. Part 3 and Ian comes to inspect.

Sunshine Mine Fire Disaster Idaho November 1972 MSHA
 
00:51
The Sunshine Mine near Kellogg, ID, was the nation's premier silver producer for many years. In 1972, the mine was nearly 6,000 feet deep, contained hundreds of miles of worked-out areas, and employed nearly 500 people. Because of its depth and the type of host rock for the silver unburnable quartzite, the general thinking of the day was that fires in mines such as the Sunshine were impossible, because

Global Antimony Market 2015-2019 by Market Research Store
 
00:31
Antimony is used for the production of flame retardants. It is found in its ore form and usually appears as a lustrous tin-white metal. Antimony is primarily mined in China and the country holds the majority of its reserves. In 2009, the government of China has classified antimony as a strategic metal and a rare element of the earth, resulting in supply constraints worldwide. Apart from flame retardants, the other major applications of antimony are in lead batteries, as an alloy strengthening agent, a catalyst, and in ceramics. In 2014, owing to supply constraints worldwide, the EU and the British Geological Survey listed Antimony at the top of the list for metals and minerals. Global Antimony Market to grow at a CAGR of 5.03 percent over the period 2014-2019.

It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is silvery with a hint of blue; it tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes each conclude a major decay chain of heavier elements. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the group, lead tends to bond with itself; it can form chains, rings, and polyhedral structures. Lead is easily extracted from its ores; prehistoric people in Western Asia knew of it. Galena, a principal ore of lead, often bears silver, interest in which helped initiate widespread extraction and use of lead in ancient Rome. Lead production declined after the fall of Rome and did not reach comparable levels until the Industrial Revolution. In 2014, the annual global production of lead was about ten million tonnes, over half of which was from recycling. Lead's high density, low melting point, ductility and relative inertness to oxidation make it useful. These properties, combined with its relative abundance and low cost, resulted in its extensive use in construction, plumbing, batteries, bullets and shot, weights, solders, pewters, fusible alloys, white paints, leaded gasoline, and radiation shielding. In the late 19th century, lead's toxicity was recognized, and its use has since been phased out of many applications. Lead is a toxin that accumulates in soft tissues and bones, it acts as a neurotoxin damaging the nervous system and interfering with the function of biological enzymes. It is particularly problematic in children: even if blood levels are promptly normalized with treatment, neurological disorders, such as brain damage and behavioral problems, may result.
