2010-2-12  Gold telluride ores are important gold refractory ores due to the presence of sulfides and other gangue materials. The classification and main physical properties of gold telluride ores were described, and possible treatment methods including flotation, leaching, and oxidation were reviewed. The results show that flotation procedures are much easier for gold tellurides compared to other ...

Process mineralogy of gold: Gold from telluride-bearing ...

Petrographic and microanalytical studies of gold in gold-silver telluride deposits show that it occurs as “visible gold” extracted by cyanidation, and as visible gold and “invisible gold” that are unamenable to cyanidation. Two gold-bearing tellurides, calaverite and buckhornite, are considerably less amenable to cyanidation in comparison to Au-Ag tellurides. Secondary ion mass ...

Treatment of Gold–Telluride Ores - ScienceDirect

2016-1-1  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). The process (called the Emperor Process) used a basic hypochlorite (i.e., chlorine) solution to oxidize a high-grade gold telluride concentrate produced from flotation.

The large gold-telluride Svetlinsk deposit (~135 t Au) is considered to be a nontraditional one in the Urals and its origin is debated. A specific feature of the deposit is the abundance of various tellurides, such as tellurides of Fe, Ni, Pb, Sb, Bi, Ag, and Au. The new data of microthermometry, Raman spectroscopy, LA-ICP-MS, and crush-leach analysis (gas and ion chromatography, ICP-MS) for ...
