Gold Mining Methods

Gold Mining Methods

+

Summary. Historically, the majority of gold was mined from "placer deposits", where gold has settled out of an existing or ancient waterway downstream of where nuggets had eroded out of rock early miners also used an early form of hardrock mining, digging solid veins of gold out of rock, where mineralized water had deposited it over thousands of years.

Gold Extraction Recovery Processes

Gold Extraction Recovery Processes

 · The processing of gold ores has traditionally made use of conventional crushing and grinding circuits. In each case where gold is formed either as coarse native particles or in coarse grained sulphides, it is recovered by gravimetry concentration in the in the comminution circuit in addition to recovery of finer values by leaching. Jigs are the most common types of gravimetric equipment placed ...

Hard rock gold mining extracts gold encased in rock, rather than fragments in loose sediment, and produces most of the world's gold. Sometimes openpit mining is used, such as at the Fort Knox Mine in central Alaska. Barrick Gold Corporation has one of the largest openpit gold mines in North America loed on its Goldstrike mine property in northeastern Nevada. Other gold mines use ...

Gold Cyanidation

Gold Cyanidation

+

Process. Cyanide can be used to extract gold, either in a controlled mill environment, or more crudely on rock piles in the open. Cyanide "vat leaching" mixes finely crushed ore with a cyanide salt in water. The cyanide binds to the gold ions, and makes them soluble in water, thereby allowing separation from the rock. This process usually takes place inside a mill or other mining facility ...
