摘要
对低品位复杂多金属矿脱除硫化矿和磁铁矿后的尾矿,采用强磁选分组,磁性产品及非磁性产品分别进行黑钨浮选和白钨浮选,白钨浮选精矿加温精选和酸浸的工艺流程,最终得到含WO372.59%的白钨精矿,回收率30.15%,含WO355.36%的黑钨精矿,回收率47.81%。
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.
