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.
Process of Cyanide Gold Extraction
The gold content is 0.10 to 0.13 oz. per ton, none of which is free; the gold particles are attached to pyrite, and in general they are less than 1 micron in size. Cyanidation is conducted under conditions of intense aeration for a period of 6 to 8 hours. Residues run about 0.04 to 0.06 oz. gold per ton. Cyanide consumption is about 2 lbs. NaCN per ton.

Extracting Gold | HowStuffWorks
Removing the gold-bearing 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 gravel-like material then enters rotating drums filled with ...

What is Gold Extraction? (with pictures) - wiseGEEK
03.04.2020 · Gold extraction refers to the methods used to remove gold from its raw state in gold ore. A number of processes are employed to achieve extraction, including separating the gold from its surroundings by physical force, exposure to heat, or stone means. The ore is typically mined first, though this is not always necessary, and then subjected to an extraction method appropriate for its ...
