Gold extraction - QueensMineDesignWiki
Of the numerous major gold mining operations around the world, most utilize a primary crushing circuit which flows into a SAG mill circuit and then a ball mill circuit. The primary reason for the significant comminution circuits is because in gold mining the grades are notably low and thus excessive waste material is present, resulting in high ...

Major Mines & Projects - Mining Intelligence and News
Native gold is the main mineralization mineral and is commonly present as micron sized grains; coarse nuggets are rare. Gold is commonly associated with pyrite, arsenopyrite and pyrrhotite and in places with minor base metal sulphides. Quartz, chlorite, sericite and carbonates are the common gangue minerals in the gold-quartz deposits.
