摘要
综述了从含银废渣中提取银的工艺研究进展。银提取工艺按体系不同分为酸性、碱性及其他。对比了各工艺的优缺点,指出酸性体系中硫脲法提取银是较为优越的工艺。
Recovery process of silver from nonferrous metal leaching residues was reviewed.After contrasting with the merits and demerits of these recovery methods,the author considered that the process of using acidic thiourea solution to leach silver was a better technology than others.
