摘要
该铅锌矿石,铅锌氧化率高,含泥量大,给铅锌选别回收带来困难。经试验研究,采用先硫后氧工艺流程及符合环保要求的药剂制度,获得铅精矿品位56.59%,回收率89.91%,锌精矿品位40.13%,回收率75.19%,铅精矿含银品位1539g/t,回收率78.16%。
The oxide ratio of lead and zinc is high,mud qanlity in the ores is big.It is difficult to receive lead and zinc.the follows is index through using flowsheet of concentrating suphurate before oxidate and adapt agent system:lead grade of lead concentrate is 56.59%,lead recovery of lead recovery is 89.91%,zinc grade of zinc concentrate is 40.13%,zinc recovery is 75.19%,silver grade of lead concentrate is 1 539 g/t,silver recovery in lead concentrate is 78.16%.
