【摘要】：針對(duì)蛇紋石易惡化硼鎂石浮選環(huán)境的問題,通過浮選試驗(yàn)研究了不同粒度蛇紋石及礦物量配比對(duì)硼鎂石浮選效果的影響.試驗(yàn)結(jié)果表明:浮選過程中蛇紋石與硼鎂石顆粒間易發(fā)生相互作用,隨著礦樣中蛇紋石含量增加及蛇紋石粒度減小,硼鎂石回收率逐漸下降,并且細(xì)粒級(jí)蛇紋石對(duì)硼鎂石回收率影響更為明顯,能顯著降低硼鎂石回收率.結(jié)合礦物zeta電位的測(cè)定及DLVO理論計(jì)算,對(duì)溶液中礦物顆粒間作用機(jī)理進(jìn)行了分析,表明礦物表面電性差異是礦物顆粒間相互作用的根本原因.
[Abstract]:In view of the problem that serpentine can easily deteriorate the flotation environment of boromite, the effect of different particle sizes of serpentine and mineral ratio on the flotation effect of boron magnesia was studied by flotation experiments. The experimental results show that the interaction between serpentine and boramite particles is easy to occur during flotation. With the increase of serpentine content and the decrease of serpentine particle size, the recovery rate of boron magnesite decreases gradually. The effect of fine serpentine on the recovery of borite is more obvious, and the recovery rate of boramite can be significantly reduced. Combined with the determination of mineral zeta potential and the calculation of DLVO theory, the interaction mechanism of mineral particles in solution is analyzed. It is shown that the difference of mineral surface electrical properties is the fundamental reason for the interaction between mineral particles.
