The process mineralogy of g The classification of

Up to10%cash back· Abstract. The principal g minerals that affect the processing of g ores are native g, electrum, AuAg tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) g, principally in arsenopyrite and pyrite, is also important. The main causes of refractory g ores are submicroscopic g, the AuAg tellurides, and very finegrained g (<10 µm) locked in sulfides.
