Description of a new environmentally beneign gold extraction method which will make use of mercury... Mining : What Is Gold Mining? How Is Gold Mined? The largest producing gold mine in the world, the Grasberg mine in Papua, Indonesia, is primarily a copper mine. Gold ore processing Cyanide process. Cyanide extraction of gold may be used in areas where fine gold-bearing rocks are found. Sodium cyanide solution is mixed with finely ground rock that has been proven to contain gold or silver and Gold Extraction from a High Carbon Low-Grade Refractory A high carbon low-grade gold ore, in which gold mainly occurs in carbonaceous matters, is a typical refractory gold ore whose conventional cyanide leaching extraction is only 00.0 %. In this paper, by the process of flotation-roasting-leaching, gold was effectively enriched and extracted. The flotation results showed that the enrichment ratio of gold was relevant to that of carbon, indicating Gold mine extraction expected this year with more than Extraction of the first gold mines in Cambodia has been confirmed to be made within this year, as more than 00 exploration licences on non-mantel mines including gold have been issued to private
