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, the au-ag tellurides, and very fine-grained gold ( 10 m) locked in.
