Gold extraction Wikipedia
Gold extraction refers to the processes required to extract gold from its oresThis 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 ofGold 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 (eg, 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 forGold processing Mining and concentrating | Britannica
