摘要
用絮凝剂ＣＡＳ即阳离子型丙烯酰胺—淀粉接枝共聚物对硫化铜精矿、尾矿进行了沉降、过滤脱水等实验，并与３＃絮凝剂（固体聚丙烯酰胺）作了对比实验，探讨了ＣＡＳ结构对絮凝性能的影响、局限性及研究方向。
Tests of settling,filtration and dewatering of concentrate and tailing of copper sulphide were done by using cation graft copolymer of acrylamide and starch as flocculant ( CAS) . Tests of contrasting CAS flocculant with 3 # flocculant, a solid polyacrylamide were also done.The influence,limitation and research direction of CAS flocculant structure on flocculation behaviour are discussed.
