微细粒赤铁矿选择性絮凝试验研究

Research of Selective Flocculation for System of Fine Hematite and Quartz

通过采用常规絮凝剂和新合成絮凝剂絮凝对人工混合矿选择性絮凝试验,得出不同选择性絮凝剂对微细粒赤铁矿的絮凝效果优劣顺序为:淀粉丙烯酰胺接枝聚合物>磺化聚丙烯酰胺>苛化玉米淀粉,综合考虑品位和回收率指标,以淀粉丙烯酰胺接枝聚合物效果最佳。

Though the experiment selective flocculation study of the conventional Flocculant and the new synthesis of Flocculant flocculation for artificial mixed minerals,get the order of merits of three kinds of flocculants on flocculation of fine hematite-- quartz system：starch--acrylamide graft copolymer〉sulphonated polyacrylamide〉causticizing cornstarch, considering the grade and recovery index,the starch acrylamide graft copolymer best effect.
