Gold extraction - QueensMineDesignWiki

IntroductionOre Classifi ionComminution ProcessesProcess SelectionMill SizingConclusionReferencesOnce the gold ore has been removed from underground and brought to surface, an entirely new challenge begins in separating the gold from the waste material. The separation process is particularly difficult due to the usually low quantity of gold relative to waste. Common gold grades are in the same magnitude as about 5 g/t, or 0.000005% gold content by weight. This means that upgrading the concentration by a factor of 3000 to 4000 is commonly required to achieve commercial ore (Marsden & House, 2009). In or…
