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

An Overview of Basic Gold Separation Methods ...

Mar 14, 2016  Panning is a gold mining method that uses water to separate the heavy gold particles from the lighter materials in the ore. When panning for gold you put your crushed gold ore in a wide pan and then add water to it. You then swirl the pan around with the aim of removing the lighter materials along with the water.

Extraction of gold using cyanide

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.
