The process mineralogy of gold: The classification of ore ,

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 (
