摘要
针对湖南某大型钨多金属矿有用矿物嵌布粒度细、矿物组成复杂、伴生锡资源品位低、矿物可浮性差、单独回收锡成本高等难题,在磨矿细度-0.074 mm粒级占82.35%条件下,采用自主研发的新型捕收剂GYX对WO_(3)品位0.34%、Sn品位0.089%的硫化矿浮选尾矿进行了1次粗选、3次扫选、5次精选的钨锡混合浮选,获得了WO_(3)品位38.11%、Sn品位3.87%的钨锡混合精矿,钨、锡回收率分别为74.05%、29.74%,实现了对钨锡矿物的同步回收。
As for the tungsten polymetallic ore in Hunan being characterized by finely disseminated valuable minerals and complicated mineral compositions,there exist problems of the associated tin minerals with a low grade and poor floatability,high cost in flotation recovery of a single tin.Thus,a novel self-developed collector,GYX,was adopted to treat the tailings grading 0.34% WO_(3)and 0.089% Sn from sulfide ore flotation,after ground to a fineness of-0.074 mm 82.35%.By using a close-circuit tungsten-tin bulk flotation flowsheet consisting of one stage of roughing,three stages of scavenging and five stages of cleaning,a tungsten-tin bulk concentrate grading 38.11% WO_(3)and 3.87% Sn was finally produced with the corresponding recoveries of 74.05% and 29.74%.It is shown that this approach can achieve the synchronous recovery of tungsten-tin minerals.
