Tellurium Ore Processing

  • Processing technologies for gold-telluride ores

    2016-9-12 · Abstract: 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 oxida-tion were reviewed. The results show that flotation procedures are much easier for gold tellurides compared to other refractory gold-bearing ores. For the conventional cyanide leaching process, Treatment of Gold–Telluride Ores ScienceDirect,2016-1-1 · However, by 1907, the use of roasting to oxidize the ore prior to cyanidation of the calcine was firmly established as a major method of treatment of Cripple Creek ore. By the use of a roasting step, the tellurium was burnt off as a gas, leaving behind the gold, which was

  • Tellurium Production

    Tellurium is extracted by sulphide ores processing from semi-products of copper, lead-zinc manufacture, as well as from some gold ores. Copper electrolysis sludge which contains from 0.5 to 2% Tellurium, as well as silver, gold, selenium and copper may me used as main feed stock in Tellurium production.The behavior of tellurium during copper ore ,It was found that Te oxidizes during the Cu ore smelting process, with 44% Te4+ in the flash furnace SO₂ filter. Te also showed 32% Te4+ in the raw and pressed anode slimes. The doré furnace soda slag and dust filter showed the most oxidation of Te at 57% Te4+ and 60% Te6+ respectively.
