Metallurgy for Recovering Gold from Telluride Ore

2020-05-19· Gold ore associated with Telluride is hardly soluble in ordinary cyanide solutions and special treatment is necessary for its extraction. There are two methods in use in such cases. Roasting. The ore is ground dry to about 30 mesh and roasted; it is then ground to a slime in water or cyanide solution, usually in grinding pans, utilizing the opportunity simultaneously to amalgamate any gold

OverviewPhysical and chemical propertiesStructureOccurrenceSee alsoFootnotesSources

Calaverite, or gold telluride, is an uncommon telluride of gold, a metallic mineral with the chemical formula AuTe2, with approximately 3% of the gold replaced by silver. It was first discovered in Calaveras County, California in 1861, and was named for the county in 1868. The mineral often has a metallic luster, and its color may range from a silvery white to a brassy yellow. It is closely related to the gold-silver telluride mineral sylvanite, which, however, contains significantly mor

Treatment of Gold–Telluride Ores ScienceDirect

Treatment of telluride ore began in Vanuwtu, Fiji, in 1934 using a conventional refractory treatment circuit using roasting followed by cyanide leach of the calcine. A hydrometallurgical treatment method for the leaching of gold telluride along with the production of tellurium metal was devised at Emperor Gold Mine (Cornwall and Hisshion, 1976).
