What Is Involved in Molybdenum Mining,2013 - I

molybdenumThe process of molybdenum mining depends on the laws in the locations within the country where veins of ore have been discovered. If the ore is found deep, subsurface mines are dug. If it is on the surface or at a shallow depth, surface mining techniques are employed. The U.S. Environmental Protection Agency is a good source for information about the strip mining of molybdenum. When a discovery of ore is made in the United States near the surface, the procedure for molybdenum mining is as follows: clear the site of brush and topsoil, remove the ore, and restore the location to its former appearance.

Molybdenum, also referred to as moly, is element 42 on the periodic table of elements, a chart that lists the different types of atoms that exist and the characteristics that each possesses. Molybdenum ore, or molybdenite, is slippery to the touch and leaves a black mark when moved across a light surface. It was originally mistaken by many for lead. In 1781, Peter Jacob Hjelm isolated molybdenum as a pure element, belonging to the same chemical family as chrome and tungsten, elements known for strength and heat tolerance.

Molybdenite has been located and mined in China, the Russian States, Chile, Canada, Peru, and in the United States near the continental divide. The mines may yield different products or combinations of products: molybdenum only in primary sources, copper ores in by-product sources, and both molybdenum and copper in co-product sources. Molybdenum mining prospectors drill into proposed exploration sites and extract core samples every few thousand feet (1000 ft = about 305 m). These cylindrical samples are removed from hundreds of feet (100 ft = about 30.5 m) into the bedrock.
