摘要
凡口铅锌矿入选原矿属于高硫型铅锌矿石,矿物呈粗细不均匀嵌布,黄铁矿易浮,铅铁分离困难。通过试验研究,突破选铅pH值的限制,采用高碱度、细磨、混合捕收剂、快速浮选和新型抑制剂等技术,使选矿经济技术指标获得了大幅度提高,为分离高硫铅锌矿石提供了丰富的实践经验。
The run of mine ore of Fankou Lead-Zinc Mine belongs in high sulfied type lead-zinc minerals The minerals was shown coarse fine inhomogeneous dissemination.pyrite was easy of flotation, lead and iron difficult to separate.Through scientific research,break lead concentration pH value,it was introduced that technique of high alkalinity,fine grinding,mixed collectors,high-speed flotation and new type depressant.The index of concentration economic techniques were improved by a wide margin.The rich practice experiences were provided to separate high lead-zinc sulfide minerals.
