摘要
为了提高金东矿业铅锌矿中铅精矿的品位与回收率,采用原生电位浮选技术,对铅回路进行了药剂制度的优化。工业试验结果表明,通过增大石灰用量,改变石灰添加地点,加入锌抑制剂与磁黄铁矿抑制剂,稳定了矿浆p H与电位,使铅精矿的品位从30.65%提高到56.46%,回收率从64.41%提高到89.52%,铅精矿中银的品位和回收率分别达到1514.2 g/t和70.13%,年增经济效益487.5万元。
In order to improve the grade and recovery of lead concentrates in lead-zinc ores of Jindong Mining, the technology of origin potential flotation was used and the medicament system in lead circuit was optimized. The results of industrial tests showed that： the slurry pH values and potential values were controlled to be stable by adding lime and inhibitors of sphalerite and pyrrhotine. The grade of lead concentrates raised from 30. 65% to 56. 46%, and the recovery from 64. 41% to 89. 52%. The silver in lead concentrates got a higher grade with 1 514. 2 g/t and recovery with 70. 13% . Comparing the industrial tests to the previous mineral process, the economic benefits may increase 4. 875 million annually.
