Process to Reduce Ash in Flotation of Hard

The most proportion of mineral impurities in this coal sample is Kaolin, which is very argilliferous and harmful for fine coal flotation. In this paper, the authors use recleaning process and add depressant inslurryto reduce the concentrate ash. The results show that the most appropriate depressant is sodium haxametaphosphate and the best flotation conditions are 80g/L feed concentration, 0
