| 摘 要： | 通过单矿物浮选试验，研究了油酸钠体系中微细粒赤铁矿的浮选行为，并考察了六偏磷酸钠、硅酸钠、焦磷酸钠、淀粉、腐植酸钠这5种抑制剂对微细粒赤铁矿可浮性的影响。结果表明：在油酸钠浓度为4×10-4 mol/L、pH=10时，微细粒赤铁矿的浮选效果最佳。5种抑制剂对微细粒赤铁矿均表现出明显的抑制作用，它们抑制能力的强弱排序为淀粉＞腐植酸钠＞焦磷酸钠＞六偏磷酸钠＞硅酸钠。

| Abstract: | Flotation behavior of ultrafine hematite and the effect of five types of depressors(sodium hexametaphosphate,sodium silicate,sodium pyro-phosphate,starch,sodium humate)on ultrafine hematite recovery in NaOl flotation system were researched.The results show that ultrafine hematite reaches to good floatability when the concentration of sodium oleate is 4×10-4 mol/L and pH value is 10.The five types of depressors all have obvious depression on ultrafine hematite flotation,organic depressors have a better depression effect than inorganic depressors,and the depression effects of the five depressors are in the order of starch>sodium humate>sodium pyro-phosphate>sodium hexametaphosphate>sodium silicate. |
