锡精炼硫渣除铜生产实践

摘要

锡火法精炼系统加硫除铜产出的硫渣(铜渣)含有较高杂质铜，为了减小杂质铜在锡系统的循环，通过将硫渣焙烧、浸出的工艺实现杂质铜在锡系统生产过程的开路，综合回收有价金属铜。%Sulfur will be added in the tin fire refining process to remove copper from raw tin. The copper will be enriched in the sulfur slag (copper slag). The copper will be recovered from the sulfur slag by roasted and leaching process which can reduce copper impurities circulates in the tin smelting system.
