Gongyi Xin Hua Machinery Mining knowledge editors: Gold gold extraction methods. If that is a primary sulfide ore mine slag machine operation, generally finely ground ore after 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 fine gold After the powder sent to the smelter smelting of 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 electric slag accessories, under alkaline conditions is to use cyanide leaching solution was stirred after the ore milled (or heap leaching), and containing gold was treated with activated carbon adsorption of gold, and finally through the activated carbon resolve electrolysis high purity finished gold. To take into account the value of mining transportation, processing, and other conditions exposed situation, it is important to also consider the issue of the content of harmful substances, is the content of phosphorus pentoxide, exceed the allowable value will increase the difficulty dressing, that increase costs, ore The price will be implicated. Mineral exploitation and comprehensive consideration, comprehensive evaluation, utilization. Lead and zinc prices continue to rise sharply recently on May 10, according to the market price monitoring, Youxi 9400 yuan per ton, lead concentrate, rose 400 yuan, or 4.4 percent both zinc concentrate 7600 yuan per ton, up 1400 yuan , gains were 22.6% was sustained upward trend. Mineral prices continued to rise mainly due to: the national launch of non-ferrous metal industry revitalization plan Cinder machine to ensure the smooth operation of non-ferrous metal industry, electric machines offer Cinder, speed up industrial restructuring, promote industrial upgrading; domestic car production and sales hit consecutive months the highs, the automotive industry as a whole to further pick up, because the lead car battery is the main raw material, market demand for lead and zinc prices increased pulling power Cinder how much money, Xinhua machinery (certified), Nanchang slag machine consists of Gongyi City Xinhua machinery factory provided. Gongyi City Xinhua Machinery Factory (www.gyxinhua.com) is a leader in Zhengzhou, handling equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Xinhua leader in mechanical staff warmly welcome all inquiries negotiations to create a better future, Xinhua machinery.
