| 摘 要： | 通过浮选实验,研究了玉米淀粉,糯玉米淀粉,酸裂解玉米淀粉,1号淀粉,马铃薯淀粉,木薯淀粉在调军台铁矿浮选中的作用效果.研究结果表明各种淀粉对赤铁矿都有一定的抑制作用,各种淀粉的的分子量不相同,支链部分和直链部分的比例不同,是淀粉对赤铁矿抑制作用存在差别的主要原因.

| Abstract: | The effect of some depressors of maize starch,waxy-maize starch,dextrine,No.1 starch,patato starch,tapioca on the floatability of hematite which comes from Diaojuntai was studied.The results shows that every starch (composed of amylose and amylopectin) has certain depression on hematite.Amylopectin is a mixed flocculent reagent,the effect of flocculate isn't obvious.Different molecular weight and proportion of amylose and amylopectin of every starch has a contribution to the difference of the effect of depression. |

| Keywords: | depressor amylose amylopectin flocculent reagent |
