Pulverized spent automobile catalyst was leached with acidic solns. (optionally with HA). The leachates were liq.-liq. extd. with com. org. phase-contg. complexants to remove Fe(III), Mg(II) and Zn(II) ions and to sep. them from Pt group ions present in the raffinate. Co(II) ions were also recovered by using a com. complexant. The ultrafiltration in presence of surface active agents resulted in sepn. of Co(Il) ions from Zn(II) ions.
