Application of flotation concentrate recleaning technology in Kongzhuang coal preparation plant

In order to solve problem of low recovery of flotation concentrate caused by high-ash flotation concentrate and low-ash tailings slime in Kongzhuang coal preparation clant,appropriate flotation concentrate recleaning technology is studied and established by relevant technology in China. After application of this technology,yield of flotation concentrate is increased,so that loss of the concentrate carried in tailings slime is reduced,which makes remarkable economy benefit.
