What is Metal Recycling and How to Recycle Metal ...

The recycling of metal reduces the growing demand for natural resources such as ore. When more and more metals are recycled, the demand for the natural metal is reduced. On top of that, less energy is required to process scrap metal than it is required to extract ore from the earth, purify it and later shape it into desired shapes and sizes.

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.
