摘要
针对银山难选铅锌矿石无氰分离工艺研究,采用铅锌依次优先浮选流程,经小型闭路试验获得铅精矿品位54.50%,回收率77.66%;锌精矿品位49.60%,回收率87.50%的指标。
Considering the difficulty to separate lead ＆ zinc with non- cyanide process at Yinshan mine, this paper analyzes the method to utilize preferential floatation process to recover lead and zinc by sequence. A pilot close - loop test shows M. 50% grade lead concentrate, with 77.76% recovery, as well as 49.60% grade zinc concentrate, with 87.50% recovery.
