Gold extraction

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

Precious Metal Ores, Gold, Platinum, Silver and Copper

Platinum ores nearly always form in strongly basic rocks that are also commonly rich in iron, chrome and nickel. Many of them form via some process of magmatic segregation from molten rock as it cools in the earth. Unlike gold and silver ores, platinum ores are almost never present in quartz veins.

Utahs Gold History Utah Geological Survey

Silver ores kept the district alive until around 1880. About 1883, gold bearing ores were found, but the gold could not be separated from the rock. Disappointed, prospectors again left the district. Then, in 1889, these ores were rediscovered and the gold successfully recovered using the newly developed cyanide leaching process.
