Gongyi Xin Hua Machinery Mining knowledge editors: Gold gold extraction methods. If that is a primary sulfide ore mine, is generally carried out after grinding the ore enrichment by flotation for gold powder, mainly used in a lot of flotation reagents, and finally get the content of the fifties and sixties or even higher after gold concentrates sent finished gold smelter smelting. 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) Crawler Cinder machine and containing gold solution with activated carbon adsorption of gold slag machine, and finally through the activated carbon of high purity analytical electrolysis finished gold. Gold mine in Heilongjiang province. Mohe gold and call Martha historic Gold River, there are records in the history of the Qing Dynasty. 1970s found Tuanjiegou gold 1980s discovered a mountain of old gold mine slag machine crawler chassis and has a large-scale development. Heilongjiang has the size to about 400 multiple-point explosion Gold crawler-type slag machine, where more than 300 sand gold mine, more than 70 gold gangue. Gold production increased steadily. Gold is mainly distributed in Heilongjiang province Mohe, Huma, Aihui, Luobei, birch, Muling and East Ning, etc., formed from north to south "gold trim," accumulation area is generally square 500-2000 km, a maximum of 6,000 square kilometers.
