Gold extraction

Gold extraction

Gold extraction refers to the processes required to extract gold from its ores. This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore. Gold mining from alluvium ores was once achieved by techniques associated with placer mining such as simple gold panning and sluicing, resulting in direct recovery of small gold nuggets and flakes. Placer mining techniques

The mining and processing of mineral ores results in the production of large quantities of residual wastes that are for the most part earth or rock like in nature. It is estimated that the mining and processing of mineral ores generate approximately 1.6 billion metric tons (1.8 billion tons) of mineral processing waste each year in the United States.
