  • Natural Gold Ores and Minerals Nevada Outback Gems

    Within gold ores, the element occurs in nature chiefly as native gold, which is by far the most common gold bearing mineral In various gold ores, the native gold commonly occurs as tiny particles contained within sulfide minerals such as pyrite Iron pyrite is an exceedingly common associate with goldCommon gangue minerals in gold ores include quartz, fluorite, calcite and pyrite, but many others can be found in smaller amounts Gold Ore Minerals: The most prominent is native gold most of the native gold contains a small amount of silver, copper, platinum, etc Telluride minerals are the most common minerals which contain significant goldThe Source of Gold Its Ores and MineralsThe principal gold minerals that affect the processing of gold ores are native gold, electrum, AuAg 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 AuAg tellurides, and very finegrained gold (<10 µm) lockedThe process mineralogy of gold: The classification of ore
