摘要
铂族精炼中的溶剂萃取法比传统的沉淀法具有许多优点。本文简述铂族溶剂萃取机理,分析了目前国际上精炼厂所采用的3种萃取流程,还介绍了我国铂族金属溶剂萃取技术及机理研究的新进展。
Solvent extraction technique in the refining of platinum metals has many obvious advantages over the traditional precipitation method. The solvent extraction of platinum metals which are divided into compound formation extraction, solvolytic extraction and ion-pair formation according to the extraction mechanism have been discussed. The solvent extraction technological processes for Inco, MRR and Lonrhon refining plants were briefly introduced and reviewed. Finally some new achievements in the technology and the studies on extraction mechanism of plteinum metals were also represented.
