Selective recovery of Fe(III), Pd(II), Pt(IV), Rh(III) and Ce(III) from simulated leach liquors of spent automobile catalyst by solvent extraction and cementation
A hydrometallurical process was developed to recover Fe(III), Pd(II), Pt(IV), Rh(III) and Ce(III) from the leach liquor of spent automobile catalysts. Fe(III) was first separated by extraction with tri-butyl-phosphate (TBP). Extraction of the raffinate with tri-isooctylamine (Alamine 308) led to co-extraction of Pd(II) and Pt(IV). They were separately stripped from the loaded Alamine 308 by using a mixture of HCl and thiourea with different concentration. After the recovery of HCl in the raffinate by extraction with tri-2-ethylhexyl amine (TEHA), Rh(III) was recovered by cementation with zinc metal powder. A process flow sheet with the corresponding McCabe-Thiele plots for extraction and stripping was proposed.
