摘要: 通过单矿物浮选试验考察了油酸钠体系中微细粒胶磷矿的可浮性,并比较了六偏磷酸钠、硅酸钠、焦磷酸钠、淀粉、腐植酸钠这5种抑制剂对微细粒胶磷矿的抑制效果。试验结果表明:油酸钠浮选微细粒胶磷矿的适宜条件应为矿浆温度45 ℃、用NaOH调节矿浆pH=10、油酸钠用量6×10-4 mol/L;5种抑制剂对微细粒胶磷矿抑制能力的强弱排序为腐植酸钠>六偏磷酸钠>淀粉>焦磷酸钠>硅酸钠。

Abstract: Flotation behavior of ultrafine collophanite in sodium oleate flotation system is investigated and the five types of modifiers including sodium hexametaphosphate, sodium silicate, sodium pyro-phosphate, starch, sodium humate on ultrafine collophanite recovery are researched through flotation tests of single mineral. The results showed that the appropriate conditions for flotation of ultrafine collophanite with sodium oleate were pulp temperature 45 ℃,pulp pH = 10 adjusted by NaOH, sodium oleate of 6 × 10-4 mol/L; The inhibiting performance of five inhibitors on ultrafine collophanite is listed in order as sodium humate>sodium hexametaphosphate>starch> sodium pyro-phosphate>sodium silicate.
