Gongyi Xin Hua Machinery Mining knowledge editors: Gold extraction of gold. The content of gold in the ore mines low slag machine, in order to extract gold ore crushing and grinding needs and beneficiation methods using pre-enrichment or separation of gold from ore manipulation. Gold mineral is used in more re-election and flotation, gravity separation occupies a very important position in placer gold production, flotation is widely use rock gold mine beneficiation methods, currently about 80% of the country rock gold mine Using this method with gold, mineral processing technology and equipment have been greatly improved. Mining method definition: What is mining method? To return to the mining of ore slag block machine, block in the mines and in the surrounding rock mining conducted prospective, cutting the total recovery, called mining methods. Mining methods include: mining standards, cutting and mining iron ore mining slag machine, ie, quasi-mining, cutting and make order in space and conducted it with the mining work organically with the work in a reasonable time called mining methods.
