Conspectus of Mineral Processing. Chromite (FeCr2O4), specific gravity 4.3-4.6, hardness 5.5-7.5, is the only useful mineral for chrome ore beneficiation, which also can be used as high grade refractory. It has weak magnetism. Generally the harangue minerals have iron ore, which make trouble for strong magnetic separation.

Gold is normally mined by 4 different methods. Placer mining, hard rock mining, byproduct mining and by processing gold ore. In placer gold mining, the gold is retrieved by metal detecting, panning, cradling, sluicing and dredging.Using gravity and water to separate the dense gold from the other materials that surround it, this is the most common gold mining category for amateur gold hunters.
