| 摘 要： | 研究了浮选药剂对单矿物浮选的影响、磁铁矿对赤铁矿浮选的影响。单矿物浮选研究表明，pH〉10时，NaOH的用量的对石英矿的浮选影响大于磁铁矿、赤铁矿的浮选。随着淀粉用量的增加磁铁矿和赤铁矿的回收率逐渐增加，当淀粉用量为10mg／L时，赤铁矿的浮选几乎受到完全的抑制。CaO对磁铁矿、赤铁矿的浮选几乎没有影响，然而对石英的浮选确有很大的影响，石英的回收率随着CaO用量的增加逐渐降低。磁铁矿、赤铁矿以及石英的回收率随着捕收剂用量的增加逐渐降低。人工混合矿浮选研究表明，赤铁矿浮选品位随着磁铁矿含量的增加逐渐增加。

| Abstract: | Study magnetite effects on hematite flotation and flotation reagent on single mineral flotation. Study on single mineral flotation show when pH 〉 10, flotation of quartz ore of the influence of the amount of NaOH is larger than that of magnetite, hematite. The recovery of magnetite and hematite rate increases gradually, with the increase of starch content, when the starch content was 10mg/L, the flotation of hematite is almost complete inhibition. Almost no effect of CaO on magnetite, hematite flotation, howeveron the flotation of quartz has great influence, quartz recovery ratewith the increase of the content of CaO gradually decreased. Magnetite,hematite and quartz recovery rate reduced with theamount of collector increased gradually. Study on Flotation of artificial mixed minerals show, hematite flotation grade increased with the increase of magnetite content. |
