The chemical nature of rhodium in the chloride solution is very complicated. Its separation and purification have been the problems in the extraction and smelting of precious metals. The research progress of rhodium separation by activated solvent extraction at home and abroad in recent ten years is summarized. It is pointed out that the rhodium-containing liquid can be activated by some reagents to improve the extractability of rhodium. The activation conditions of rhodium and the separation and recovery of rhodium by adding different reagents such as SnCl2, SCN-, I- and Br- into the solvent extraction system are discussed Happening. The application prospect of separation and recovery of rhodium by activated solvent extraction is pointed out.
