Gold extraction - Wikipedia

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 recov

Gold Extraction Process - Know How Gold Is Mined My Gold ...

The process used to extract gold involves strategically drilling and blasting rocks. Plans laid out by engineers and geologists prior to mining take a lot of preparation and often show the precise position of the gold within the rocks. As a result of this, miners are able to extract large quantities of gold-laden rock, referred to as the ore.
