· High of 13 Hongshan Hubei Daye Shitouzui in dealing with copper to copper mineral malachite mainly when using the multistage multipoint of adding Na2S concentrate ore flotation method reduces the circulating concentrate grade than the production process increased 211 copper, gold recovery 25198 and 10181 respectively.
· Gold flotation reagents can be divided into 5 types: collectors, ing agents, inhibitors, activators, and pH regulators. Flotation reagent is one of the key factors affecting the flotation of gold ore. It can adjust the surface properties of gold ore during the flotation process, and improve the flotation speed and selectivity.
