Extraction of gold using cyanide Home » NZQA

2015-8-24  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.

Mechanism of selective gold extraction from multi-metal

The electrodeposition-redox replacement (EDRR) process is a promising method for a selective extraction of minor metals from complex mixtures.

The concept of amine basicity is discussed and used to explain the selective extraction of gold from alkaline cyanide solution. The apparent basicity of simple weak base amines with respect to Au(CN) 2 can be increased as much as 5 orders of magnitude by the addition of organic phosphorus oxide compounds (TBP, DBBP, etc.). It has been shown that the modified amines do not exhibit this effect
