摘要/Abstract

摘要： 为了缓解萤石资源严峻形势，提高低品位难选萤石矿以及共（伴）生型萤石矿的综合利用水平，结合矿石性质分析基础上，进行了系列条件试验研究、部分流程开路试验研究以及全流程闭路试验研究，研究结果表明：在一次粗选二次扫选，粗精矿再磨后进行五次精选，中矿顺序返回的原则流程条件下，以油酸为捕收剂、水玻璃和腐植酸钠为组合抑制剂、碳酸钠为pH调整剂，可实现该白钨多金属矿尾矿中萤石二次资源的有效回收利用；当捕收剂油酸用量450 g／t，组合抑制剂2．8 kg／t，碳酸钠1 kg／t时，在给矿CaF2品位16．41％的条件下，获得了CaF2品位为87．92％、CaF2回收率为53．53％的萤石精矿。

Abstract: In order to alleviate fluorite resources situation , and enhance the utilization level of low grade refractory fluorite and intergrowth ( associated ) fluorite, and combined with an analysis on the ore properties , the author conduct series condition test , part of the process open circuit test , and whole process closed circuit test research .Study results confirms in a second of scavenging for rough , rough concentrate again five selected after grinding , the order of middlings was returned to the principle of process conditions , with oleic acid as the collecting agent , sodium silicate and sodium humate as the composite inhibitor , sodium carbonate as pH adjusting agent , which can realize the white tungsten polymetallic ore tailings of fluorite recycling secondary resources effectively .When the dosage of collector oleic acid 450 g/t, composite inhibitor 2.8 kg/t, sodium carbonate is 1 kg/t, under the condition of 16. 41%feed grade of CaF2 , obtained CaF2 grade of 87.92%, CaF2 fluorite concentrate recovery was 53. 53%.
