How Does Gold Extraction Work?
Extracting gold is a multi-step process that can be approached in different ways depending on how a company is prospecting and mining its gold supply. For example, placer mining, which was popular during the 19 th-century gold rushes, relies on a gravity-separation extraction process. In these cases, water is used to separate gold particles ...

The Merrill Crowe Process For Mining Gold
Gold is mined in the form of microscopic particles in concentrations as little as 0.5 parts per million (ppm). As a result, simple tools have been replaced by complex equipment and chemical processes to extract gold. Today, one of the most popular methods for gold extraction is the Merrill Crowe process. The process can be summarized as follows:

Gold Metallurgy | SpringerLink
Amalgamation is an ancient gold extraction method in which gold and mercury can form an amalgam to separate gold from other metal minerals and gangues. The whole production process includes four stages: amalgamation, amalgam washing, amalgam filter pressing, and amalgam distillation.
Gold Chlorination Processes & Methods
Chlorination Process for Gold. This process was based on the fact that chlorine, in the presence of moisture, converts gold into the trichloride AuCl3, which is soluble in water and removed by washing, the gold being then precipitated by ferrous sulphate, sulphur dioxide, hydrogen sulphide, or charcoal.
Gold mining process | PPT
Gold mining involves processes to extract gold from the ground. There are several methods used including placer mining, open-pit mining, hard rock mining, and byproduct mining. Placer mining recovers gold from alluvial deposits using techniques like panning, sluicing, dredging, and cradling.
