Extraction of Gold
Gold can be extracted by washing only when it is present as metal in the form of particles which are not too minute. The washing removes the specifically lighter parts of the material, the heavier gold particles sinking to the bottom. The process is applicable directly to gold- bearing sand, and to gold-

Feb 23, 2009· Leaching dissolves the gold out of the ore using a chemical solvent. The most common solvent is cyanide, which must be combined with oxygen in a process known as carbon-in-pulp. As the cyanide and oxygen react chemically, gold in the pulp dissolves. When workers introduce small carbon grains to the tank, the gold adheres to the carbon.

Extraction of gold using cyanide NZQA
Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.
