Gold Ore Processing ScienceDirect

For the recovery of gold from refractory ores and concentrates, roasting has been used extensively for decades. For severe refractory gold ores, it was the exclusive pretreatment process and, accordingly, its development is presented in detail in this chapter, finishing with the most recent technology: oxygenated roasting for whole ores.

The process mineralogy of gold: The classification of

The principal gold minerals that affect the processing of gold ores are native gold, electrum, AuAg tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the AuAg tellurides, and very finegrained gold (<10 µm) locked
