| 摘 要： | 通过浮选试验、Zeta电位测试、TOC测试及红外光谱测试对甲基纤维素在黄铜矿与滑石浮选分离中的作用及其在两种矿物表面的吸附机理进行了研究。浮选试验结果表明,低用量的甲基纤维素可有效抑制滑石,但对黄铜矿抑制效果很弱,可实现黄铜矿与滑石的浮选分离。甲基纤维素作为滑石的抑制剂,浮选分离黄铜矿和滑石混合矿。人工混合矿Cu品位为15.19%时,可以获得铜精矿Cu品位为24.08%,回收率达74.68%的指标。检测结果表明,甲基纤维素在黄铜矿和滑石表面均发生了物理吸附,且在滑石表面的吸附强于在黄铜矿表面的吸附。

| Abstract: | The effects of methylcellulose on the separation of chalcopyrite and talc and its adsorption mechanism on the surface of two minerals were studied by flotation experiments, zeta potential test, TOC test and infrared spectroscopy. The results of flotation experiments show that low dosage of methyl cellulose can effectively depress talc, but the effect on chalcopyrite is very weak, and the flotation separation of chalcopyrite and talc can be realized using methylcellulose as depressant. Methylcellulose is used as depressantof talc to float and separate chalcopyrite and talc mixed ore. When the artificial mixed ore Cu grade is 15.19%, the Cu grade of copper concentrate is 24.08%, and the recovery rate of copper is 74.68%. The test results show that methylcellulose is physically adsorbed on the surface of chalcopyrite and talc, and the adsorption on the surface of talc is stronger than that on the surface of chalcopyrite. |
