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
