  • 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 goldladen rock, referred to as the ore The ore is then transferred to the mill to extractRemoving the goldbearing 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 gravellike material then enters rotating drumsExtracting Gold HowStuffWorksGold 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, resultingGold extraction Wikipedia
