摘要: 通过淀粉对赤铁矿的抑制机理分析,经过浮选试验,研究了玉米淀粉、糯玉米淀粉、马铃薯淀粉、木薯淀粉在齐大山铁矿选矿分厂浮选中的作用效果。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 corn starch, waxy corn starch, potato starch and cassava starch on the flotation for Diaojuntai iron ore is studied through the analysis of the depression mechanism of starch for hematite and the flotation test.The results indicate that these starches all have certain depression effect on the hematite and the difference in their depression effect for the hematite lies in their different molecular weight and their ratio of the branched chain to linear chain.

Key words: Hematite, Corn starch, Waxy starch, Potato starch
