  • Metallurgy for Recovering Gold from Telluride Ore

    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 thatОнлайн-запрос

  • Method to extract gold from telluride ores and concentrates

  • Processing technologies for gold-telluride ores

    The presence of gold telluride minerals may render an ore refractory, the extent of this depends on the telluride mineral present and the mineralogical association [3]. Gold, silver, and gold/silver-telluride minerals in ores dissolve more slowly than native gold in cyanide solutions, which results in less efficient gold extraction [4].
