| Abstract: | The tailings of a low-grade complex polymetallic ore removed sulfide ore and magnetic iron ore are divided into magnetic products and non-magnetic products by high-intensity magnetic separation.Then wolframite flotation and scheelite flotation of these two kinds of products were carried out.Finally,the scheelite concentrate of 72.59% WO3 with the recovery of 30.15% by using the technological flowsheets of hot cleaning flotation-acid leaching and the wolframite concentrate of 55.36% WO3 with the recovery of 47.81% are obtained respectively. |
