摘　　要：为了选择一种较好的赤铁矿反浮选抑制剂,通过浮选实验、动电位和吸附量实验,研究了木薯淀粉、玉米淀粉、马铃薯淀粉、苛化木薯淀粉,苛化玉米淀粉和苛化马铃薯淀粉对赤铁矿和石英的浮选性能、动电位以及吸附量的影响。研究表明这几种淀粉中,苛化木薯淀粉对赤铁矿抑制能力最强,且在赤铁矿反浮选中有较好的选择性。In order to select a kind of better depressant for the reverse flotation of hematite, the influences of cassava starch, corn starch, potato starch, causticizing cassava starch, causticizing corn starch, and causticizing potato starch on flotation performance, zeta potential and adsorp- tion amount for hematite and quartz were studied by experi- ments. The experimental results showed that causticizing cassava starch had the strongest suppression and better se- lectivity in the reverse flotation of hematite.
