Gold extraction refers to the processes required to extract gold from its orThis 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.
The gold, which occurs as grains of between a few tens of micrometres and submicron size, is not amenable to direct cyanidation These ores are beneficiated by bulk flotation using sulphydryl collectors and the resulting concentrates are then pyrometallurgically processed to produce gold and copper.
