Process mineralogy of gold: Gold from telluride-bearing ores

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

2021-3-11 · et al, 2018). In refractory gold ores, the gold is highly encapsulated in the sulfide matrix and pre-treatment is an important process to recover gold from the sulfide minerals. The sulfide minerals interfere with recovery of gold thus it is imperative to remove the sulfide minerals prior to leaching.
