从锌电解阳极泥中回收锌锰并富集铅银的试验研究

Experimental study on recovery of manganese from zinc anode slime and enrichment of lead and silver

试验研究了一种从锌电解阳极泥中回收锰并富集铅银的新工艺,该工艺处理成本低,可脱除50%的钙镁;锰锌有价金属可高效回收,回收率大于95%,且锰以符合标准的碳酸锰产品回收;铅银可富集4倍以上,利于后续工序的处理。

The paper studies a new process to recover manganese and enrich lead and silver from anode slime of zinc electrolysis, which features lower treatment cost and removing 50% calcium and magnesium. Valuable metals such as manganese and zinc can be effectively recovered with rain. recovery of 95%. Manganese is recovered in form of manganese carbonate product in compliance with standards. Four times or even more of lead and silver can be enriched, which is beneficiary for follow-up treatment.
