摘　　要：针对微细粒黑钨矿难以浮选回收的世界性难题,通过制备疏水性纳米粒子浮选捕收剂,用于微细粒黑钨矿的浮选。试验结果表明该类捕收剂对于微细粒黑钨矿浮选可行,并且阳离子型纳米粒子捕收剂的浮选效果要优于阴离子型纳米粒子捕收剂。Aiming at the global problem that fine-grained wolframite is difficult to be recovered by flotation,a hydrophobic nanoparticle flotation collector is prepared for the flotation of fine-grained wolframite.The experimental results show that this type of collector is feasible for flotation of fine-grained wolframite,and the flotation effect of cationic nanoparticle collector is better than that of anionic nanoparticle collector.
