II:The state of gold ore in the nature
Gold-bearing mineral have 98 species, 47 kinds of common, direct industrial value about 10 kinds,the form of generally divided into three categories, gold ore (Mountain gold mine, endogenous gold) and gold placer (alluvial, alluvial, beach type, slope deposits type and exogenous gold), and Associated gold (recovery from the non-ferrous minerals )
III:Technology: Flotation, Gravity Concentration, Amalgamation, cyanide leaching, carbon immersion
IV:Sand Gold ore industry requirement
