Metallurgy for Recovering Gold from Telluride Ore
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 that
