: serpentine; polymer; flocculation; turbidity; infrared spectrum 金川是我国最大的金属镍原料基地,拥有大型的硫化铜镍矿床.该类型矿床中,除有用矿物镍黄铁矿和黄铜矿外,还存在蛇纹石等硅酸盐脉石.其中,蛇纹石在破碎过程中易泥化,产生的微细粒级蛇纹石容易通过机械夹带进入浮选精矿[1-3],是导致精矿中镁含量过高的主要原因.因此,消除微细蛇纹石对硫... infrared spectroscopy. And then the adsorption mechanism of the polymers on the serpentine surface was analyzed. The results show that CMC and PAM are mainly physically bonded onto the serpentine surface......
leaching solution. Key words: interfacial crud; solid particle; bacteria; infrared spectrum 工业上应用生物浸出-溶剂萃取分离矿石中的铜,钴,镍等有价金属离子,取得了很好的浸出和分离效果.但在萃取分离过程中,经常产生界面乳化物,很多生产厂家受乳化影响不能正常生产,比如德兴铜矿自1997年投产以来遇到严重的界面乳化问题...红外光谱.从图7可以看出,随着萃取次数的增加,有机相在1032.36 cm-1处吸收峰强度明显降低,1685.63 cm-1处吸收峰消失.结果表明,萃取过程中P-O-H键可能与溶液中金属离子相结合形成配合物或发生断裂. 图6 煤油与10% P204的红外光谱 Fig. 6 Infrared spectra of kerosene and 10% P204 图7......
