| 摘 要： | 从湖南有色金属研究院采集的硫化金属矿渣中筛选出氧化亚铁硫杆菌,并将其应用于微细粒硫化矿的絮凝浮选实验研究。借助动电测定、微生物电镜观察研究了T.f菌与微细粒硫化矿在絮凝浮选实验中的作用形态。Zeta电位测定和微生物电镜观察结果表明,T.f菌在微细粒硫化矿表面形成了特效吸附;絮凝浮选数据表明,T.f菌作用后的微细粒硫化矿,Zn的品位提高到34%,回收率达到68.56%。这一研究为微细粒矿物废渣的资源回收提供了一条新的工艺路线。

| Abstract: | Thiobacillus ferrooxidans collected from sulfide slag was applied flocfloatation experiment of fine particle sulfide ore.With electro-kinetic determination and microbial electron microscopy,the function of T.f bacteria and fine particle sulfide ore in the experiments was studied.Zeta potential measurements and electron microscopy results show that T.f bacteria formed adsorption effects on the surface of fine particle sulfide minerals.Flocfloatation data show that Zn was upgraded to 34% and recovery rate 68.56 percent.This study provides a new technology for the recovery of waste fine particle slag. |
