oduct metal through mining

Mining and Metals

Where open pit / open cast mining is prohibitively expensive or results in the disturbance of too greater a surface area, underground mining is considered. Shaft underground mining involves sinking an access shaft (or shafts) through or adjacent to the ore body. Horizontal shafts or "adits" are cut from the shaft into the ore body "seams".

Pollution from Mining

Mercury was widely used to in California gold mines to extract the precious metal from solid ore. Between the years 1850 and 1981, more than 220,000,000 lb of mercury was used in mining in that state. Mercury and other metallic elements form an amalgam, or a solution of the solid metal in the liquid mercury metal.
