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

Extraction of Gold

The extraction of gold by the cyanide-method is of great technical importance. It is effected by lixiviation with a solution of potassium cyanide, the gold being precipitated either by addition of zinc or electrolytically. The process was suggested by Mac Arthur and Forrest in 1385, and is based on the well-known solubility of gold in potassium-cyanide solution, a phenomenon said to have been

Gold Extraction Process Methods Summary JXSC Machine

In the cyanide slurry, gold exists in the form of an anion complex Au (CN). Therefore, when an ion exchange resin method is used for gold extraction, an anion exchange resin must be used. The ion exchange reaction that takes place from the cyanide solution with an ion exchange resin is: R-OH+Au(CN)2-═R-Au(CN)2+OH-Gold extraction process flow (1) Adsorption: When the gold
