某矽卡岩型白钨矿有用矿物白钨嵌布粒度细，萤石、方解石等含钙矿物含量高，属于高含钙矿物的细粒难选白钨矿石.现场生产采用单一捕收剂及脉石抑制剂，白钨精矿质量及回收率均较低，为提高该白钨矿的选矿指标，进行了该矿石的大量工艺条件及工艺流程试验，结果表明：矿石经全浮脱硫后，采用水玻璃和六偏磷酸钠为脉石的组合抑制剂，油酸钠和731为白钨的组合捕收剂，经一粗三扫一精的闭路流程获得白钨粗精矿；粗精矿经过浓缩加温后，再经过一粗三扫五精的闭路流程浮选，获得了白钨精矿品位为65.16%，回收率为76.49%的较好的选矿指标，可为现场生产提高指标提供技术依据.

Scheelite dissemination particle size in a skarn-typed scheelite is fine with high calcium mineral content such as fluorite, calcite. It is a high calcium mineral fine refractory scheelite ore. Site productions by a single collector agent and gangue inhibitor lead to low quality scheelite and unfavorable recovery rate. Process experiments are performed by adjusting the ore process conditions to improve the scheelite mineral indicators. Crude scheelite is obtained by closed process of “one rough-three sweep-one concentrate”out of full floating desulfurization ore by using sodium silicate and sodium hexametaphosphate as the combined gangue inhibitors, sodium oleate and 731 as the combined collector. Scheelite concentrate (grade is 65.16%, recovery rate is 76.49%) is obtained by the closed process of “one rough-three sweep-five concentrate”out of the condensed and heated crude scheelite. The favorable indicators provide technology basis for improving production benefits.
