| 摘 要： | 研究抑制剂甘油基黄原酸钠(SGX)在铁闪锌矿与黄铁矿浮选分离过程中的作用机理。通过浮选实验考察该抑制剂对硫化矿物的浮选抑制行为。结果表明,用丁黄药作捕收剂,在SGX存在下铁闪锌矿能被Cu2+活化从而具有良好的可浮性,而黄铁矿不能被Cu2+活化;在pH为4-11的范围,SGX的用量小于50mg/L时,可以实现两种矿物的选择性分离。动电位分析表明,SGX在Cu2+存在的条件下不能阻止丁黄药的阴离子在铁闪锌矿表面的吸附,但能阻止丁黄药的阴离子在黄铁矿表面的吸附。吸附等温测试结果表明,SGX在黄铁矿表面的吸附量远比在铁闪锌表面量大。

| Abstract: | The depression of pyrite in marmatite flotation by sodium glycerine-xanthate (SGX) was investigated through microflotation,zeta potential and adsorption measurements.The flotation tests of mineral show that in the presence of SGX,marmatite can be activated by Cu2+ and shows good flotability,while pyrite cannot be activated and therefore shows poor flotability.At the pH value range from 4 to 11,the flotation selectivity between marmatite and pyrite is obvious when the SGX concentration is below 50 mg/L.The d... |
