Gold Gravity Concentration

19 · The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. Most gold ores, however, only require separation into two parts—the “concentrates,” in which the precious metal is ...

Treatment of Gold–Telluride Ores

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 ...
