    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 ores are extracted at a profit from the earth through mining; they are then refined to extract the valuable element, or elements.
