Extracting Gold HowStuffWorks

Removing the gold-bearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel. The gravel-like material then enters rotating drums filled with steel balls. In

Gold Extraction Process - Know How Gold Is Mined My

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. The ore is then transferred to the mill to extract the gold within it. If surveyed correctly, a good gold mine would yield close to 6.5 g of gold

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 recovery of small gold
