摘　　要：ＷＨＬ—１ 絮凝剂是一种改性丙烯酰胺—淀粉接枝共聚物，具有优良的水溶性。工业试验表明，将其加入铜精矿矿浆中，微细粒迅速凝聚成团，沉降速度大大加快，溢流中固体的质量分数低于００２ ％ 。WHL—1 is a graft copolymer of modified polyacrylamide starch. It has a good water solubility. The factory test shows that fine particles in copper concentrate can be flocculated into large lump flocs by adding the flocculant, accelerating greatly their settling velocity and reducing the mass fraction of solid in the overflow to below 0.02%.
