【摘要】 某钨多金属矿伴生有萤石资源，其钨浮选尾矿含19.66%CaF₂、45.01%SiO₂、2.99%CaCO₃，具备综合回收利用价值。针对该含萤石尾矿，开展了工艺矿物学研究及浮选试验研究，采用AP作为萤石浮选捕收剂，GA作精选抑制剂，经1次粗选7次精选的浮选闭路试验，得到萤石精矿Ca F₂品位为95.60%,Ca F₂回收率为67.74%，较好地实现了该伴生萤石资源的综合回收。更多还原

【Abstract】 A tungsten polymetallic mine was associated with fluorite resources,and its tungsten flotation tailings contain 19.66%CaF₂,45.01%SiO₂ and 2.99%CaCO₃,which has comprehensive recovery and utilization value.For the associated fluorite ore,the process mineralogy studies and flotation test research were conducted,using AP for fluorite flotation collector,GA for cleaning depressor,after closed-circuit flotation test of one roughing,seven cleanings,the fluorite concentrate with CaF₂ grade of 95.60%and CaF₂ recovery of 67.74%was obtained.It has realized the comprehensive recovery of the associated fluorite resources.更多还原
