摘要
介绍了原矿钼品位仅为0.18%的某钼铅矿经过金钼混合浮选,钼品位提高到3.3%,此时用常规浮选手段已难以继续富集,本课题采用混合精矿经过氧化焙烧、脱硫脱碳、NaCO3选择性浸出、浓缩等化学方法生产钼酸钠的新工艺。实现了金钼分离以及超低品位钼的低成本回收。
The thesis introduced that the grade of molybdenum is improved to 3.3% by mixed flotation of gold and molybdenum for a wulfenite with grade 0.18%, but difficult to improve more by conventional flotation. This subject adopted oxidation, roasting, desulfurization, decarbonization, leaching by NaCO3, concentrating and so on to produce sodium molybdate. This realized separation of gold and molybdenum , recovering at low cost for molybdenum of low grade.
