亚硫酸钠在稀贵金属冶金中的应用

Application of sodium sulfite in metallurgy of rare and precious metals

系统总结了亚硫酸钠在稀贵金属冶金中的应用。主要阐述了从铜镍合金氯化渣中脱硫富集贵金属,从铜阳极泥分金渣中分银,从高硒、碲的铜阳极泥中分离回收金、钯、铂,硒、碲的分离提纯,在盐酸介质中还原精炼金,从负载有机相中反萃金,从弱酸性介质中还原银,制备金的电镀配合物等,以期为从事相关领域的科技人员提供参考。

The paper systematically reviews the application of sodium sulfite in metallurgy of rare and precious metals, such as the enrichment process of precious metal by desulfurization from chlorination residuals of copper-nickel alloy;silver separation from gold separation residuals of copper anode slime;recovery of gold, palladium and platinum from high selenium and tellurium content copper anode slime ; separation and purification of selenium and tellurium ; re- duction of refined gold in hydrochloric acid ; reverse extraction of gold from loaded organic phase ; silver reduction from weak acidic medium;electroplating coordination compound of gold preparation and so on. The paper expects to be of reference to those engaged in related fields.
