Arsenopyrite Gold Recovery
Some gold may also occur in solid solution in the sulfides. It is a common practice in processing pyritic gold ores to remove as much gold and sulfide as possible by gravity treatment and/or flotation. Classically, the arsenopyrite concentrate is contacted with mercury to recover the free gold contents.

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