Oct 20, 2014nbsp018332leaching gold with a cyanide solution remains the most widely used hydrometallurgical process for the extraction of gold from ores and concentrates. despite the difficulties and hazards of working with cyanide, no other process has yet been proven to be an economic viable alternative.
Gold cyanidation also known as the cyanide process or the macarthur-forrest process is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.it is the most commonly used leaching process for gold extraction.
The mercury-free gold extraction method uses borax in the process of gold smelting. borax is used in the smelting process because it lowers the melting point of gold and other metals. in this method, the mining of gold-bearing ore, the grinding of the mined material and the concentrating from sluicing are the same as in the amalgamation method.
