Gold processing Gold processing Mining and concentrating The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for

Due to the use of dirty practices such as open pit mining and cyanide heap leaching, mining companies generate about 20 tons of toxic waste for every 0.333 ounce gold ring. The waste, usually a gray liquid sludge, is laden with deadly cyanide and toxic heavy metals. Many gold mines dump their toxic waste directly into natural water bodies.
