| 摘 要： | 小秦岭地区某低品位氧化钼铅矿含Mo 0.078%、Pb 0.34%，钼氧化率64.20%，铅氧化率58.06%，有用矿物粒度较细且嵌布紧密。对该矿石按钼铅混合浮选-硫化钠法浸出氧化钼-浸渣浮选回收硫化钼及硫化铅的选冶联合工艺流程进行了试验研究。结果表明，在试验确定的工艺技术条件下，可获得Mo品位为64.03%的氧化钼，Mo品位为12.56%的硫化钼粗精矿，钼总回收率为75.06%，并可获得Pb品位为43.07%、铅回收率为66.17%的铅精矿。

| Abstract: | The low-grade oxidized wulfenite in Xiaoqinling area contains Mo 0.078% and Pb 0.34%, the rate of Mo and lead oxide are 64.02% and 58.06% respectively, and the useful mineral is fine-grained and disseminated closely.This ore is studied by the beneficiation-metallurgy combination process:molybdenum lead bulk flotation- leaching molybdenum oxide by sodium sulfide method-recovery of molybdenum sulfide and lead sulfide by flotation from the leaching residue.As the results showed, the molybdenum oxide with the grade of Mo 64.03%, the molybdenum sulfide with the grade of Mo 12.56% and the lead concentration with the grade of lead 43.07% were obtained under the conditions determined by experiments, and the total recovery rate of Mo and lead were 75.06% and 66.17% respectively. |
