A process for treating a particulatedgoldbearing ore to recover thegoldtherein is disclosed. The process includes roasting the ore to remove sulfides as sulfur dioxide followed by chlorination of the ore at a temperature of about 350° C. in the presence of iron to form a mixture of volatilegoldchlorides and volatilegold-iron chlorides in thechlorineoff gases followed by condensing ...

Feb 01, 2012· 1. Introduction.Chlorinehas been used to dissolvegoldfrom ores and concentrates during the second half of the 19th century. This process was later replaced by the more economical alkaline cyanide leaching (Sparrow and Woodcock, 1995).Currently, due to the environmental problems of cyanide, there is a need to find viable alternatives to cyanide.

Although this method ofgold extractioncalls for household chemicals, that doesn't mean they are safe. Please be advised that you must handle these chemicals with care. Goggles, gloves, glass apparatus and a very well ventilated room with a fume hood (and a gas mask/respirator are needed as well) or an outside area is highly recommended.
