摘要
对比分析凡口铅锌矿上部与深部锗、镓的含量及分布规律 ,研究选矿过程中锗镓在各选矿产品中的分布及锗镓的回收。深部锗、镓分布与上部相同。锗、镓主要在闪锌矿中 ,锗在方铅矿、黄铁矿、脉石的分布极少 ,镓有部分分布于黄铁矿与脉石中。锗、镓主要富集在锌精矿中 ,在铅精矿、硫精矿及尾矿中锗、镓的占有率很低。在电化学调控浮选工艺中 ,锗、镓在锌精矿的富集得到了大幅度的提高 ,锗、镓的占有率由 87 89%、5 2 80 %分别提高到 92 73%、62 68%。
The content and distribution of Ge and Ga in depth and upper parts of Fankou Lead Zinc Mine are analyzed and compared The distribution in beneficiation products and recovery by mineral processing of Ge and Ga are investigated The distribution of Ge and Ga in depth parts is similar to the upper parts The most of Ge and Ga are in the sphalerite, a few of Ge are in the galena, pyrite and gangue, and Ga is partly in pyrite and gangue The most of Ge and Ga are in zinc concentrate, the few are in lead and sulfur concentrates as well as tailings The concentration of Ge and Ga is increased greatly in mineral processing of electrochemical potential controlling process, the recovery of Ge and Ga is raised to 92 73% and 62 68% from 87 89% and 52 80% respectively
