HOME>>Product>>free chemistry of gold extraction books download. Extraction of gold using cyanide nzqa.govt.nz. 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.
Gold is a heavy metal in a group known as the transition metals. Gold is also known as a precious metal (as are platinum and silver). Large amounts of gold are still used in the manufacture of coins, medals, jewelry, and art. Gold also has a number of uses in industry, medicine, and other appliions.

gold miners Smallscale miners Some SSM communities continue to practice the same method of gold extraction developed by their forefathers, whereas other groups are innovative and try to improve working techniques to increase gold recovery rates. An excellent example of this is a group of SSM in the Benguet province in the Philippines.
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.
