  • Rebellious Ores: Sulfides, Selenides and Tellurides

    2012-4-18  Gold bearing tellurides were important in some of the richest ores at Goldfield, Nevada – high grade ore that contained upwards of 10,000 ounces of gold per ton. If you have tellurides in your ore, it’s important that you are aware of that fact, because it affects how you will process it.

    Dziurdzak et al. (1989) investigated the pressure oxidation of flotation concentrate obtained from Kalgoorlie gold–telluride ores. The untreated concentrate, which contained 79 g/t gold, gave ∼68% gold extraction by simple cyanidation. About 40% of the refractory gold was combined with tellurium, and the balance was locked in sulfides.
