    The process mineralogy of gold The classification of ore

    Abstract. The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au Ag 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,
