内蒙某复杂铜铅锌硫化矿选矿工艺研究

内蒙某矿业公司的复杂铜铅锌硫化矿石铜、铅、锌矿物共生关系非常密切而复杂，给选矿造成极大难度。为了给该矿石的开发提供可行方案，进行了多方案的详细选矿试验，结果表明，常规浮选工艺无法有效分选该矿石，而采用铅重选-铜锌混合浮选再分离浮选的工艺流程，可以获得铅品位为57.20%、铅回收率为54.18%的铅精矿，铜品位为13.35%、铜回收率为57.11%的铜精矿和含锌18.78%、锌回收率为41.94%的富锌物料，富锌物料可以与公司其他选厂锌品位较高的锌精矿搭配销售。

Dressing Process of a Complex Cu-Pb-Zn Polymetallic Sulfide Ore in Inner Mongolian

Due to the complex symbiotic relationship of copper,lead and zinc sulfide ores from Inner Mongolian a mining company,it’s very difficult to separate.In order to develop these ores,carried out dressing tests by multiple schemes.The results show that,the conventional flotation process can’t separate these ores,but the process of lead gravity separation-bulk flotation of copper and zinc then flotation separation can get the lead concentrate with grade 57.20%,recovery 54.18%,copper concentrate with grade 13.35%,recovery 57.11%,rich contain of zinc material with zinc content 18.78%,recovery 41.94%.Rich contain of zinc material can be sold with high grade zinc concentrate from other concentrators.
