巩义鑫 China Machinery Mining knowledge editing: Species mine. Most of the elements in the crust can mineralization, many types of lead-zinc slag machine, roughly divided into metal ore and non-metallic mineral slag machine, also includes non-ferrous metal ores (precious metals), ferrous metals, rare earth, the species is more. Metals including: gold, silver, lead, zinc, nickel and cobalt chromium iron and manganese, tin and antimony, bismuth and molybdenum tungsten, titanium, non-metallic: graphite, fluorite, feldspar, quartz, barite, jade, diamond and so on. Gongyi Xin Hua Machinery Mining knowledge editors: Gold gold extraction methods. If that is a primary sulfide ore copper ore slag machine, usually after grinding the ore enrichment by flotation for gold powder, mainly used in a lot of fluorite ore flotation reagent Cinder machine, and finally get the content of five or six ten or even higher after gold powder sent to the smelter smelting finished gold. The general principles of gold ore content is very low, per ton of ore, only 2 to 3 grams or less. 2 If the oxide ore, the general cyanide gold extraction process, under alkaline conditions is to use cyanide leaching solution was stirred after the ore milled (or heap leaching), and then a solution containing gold activated carbon adsorption gold, and finally through the resolve to get high purity electrolytic charcoal finished gold. Fluorite ore slag machine _ _ Grilled slag machine mining machine provided by Gongyi City Xinhua Machinery Factory.
