摘　　要：白钨矿与含钙脉石矿物浮选分离是白钨矿浮选的难题,在传统脂肪酸工艺体系中,白钨精选多依赖于传统的"彼得罗夫法"加温工艺。研究从含钙矿物晶体表面差异性出发,开发出对钨矿物具较强选择性的金属盐类配位捕收剂M-COMPLEX,和以其为捕收剂、盐化水玻璃为选择性抑制剂的黑白钨常温精选新工艺。采用该工艺处理柿竹园多金属选厂粗选车间WO3品位17.59%的黑白钨混合粗精矿,小型闭路试验获得钨精矿WO3品位63.18%、回收率94.96%的良好指标。该工艺在工业试验中具有很好的稳定性和重现性,可达到取代白钨加温精选工艺的目的。The flotation separation between scheelite and calcium gangue minerals is a difficult problem in scheelite flotation. In the traditional fatty acid process system, scheelite concentration was decided by the traditional＆quot;Petrov＆quot;heating process. Starting from the crystal surface differences of calcium minerals, this paper developed a new concentration technology of wolframite and scheelite by applying M-COMPLEX as metallic salt ligand collector and salinization sodium silicate as selective depressant. The tungsten concentrate （the grade and recovery are 63.18%and 94.96%respectively） were obtained out of the rough wolframite and scheelite ore （WO3 grade is 17.59%）. This new process has advantages of stability and repeatability in the industrial test and achieves the goal of replacing the heating concentration technology of scheelite.
