ABSTRACT:
Metal values are extracted from aqueous solutions of metal salts containing halide or pseudo halide ions by pyridine derivatives containing the substituent --(COX).sub.A where X is the group --OR.sub.1 or --NR.sub.2 R.sub.3 and n is 1, 2 or 3. R.sub.1 is a hydrocarbyl group containing from 5 to 36 carbon atoms and R.sub.2 and R.sub.3 are hydrogen or a hydrocarbyl group wherein R.sub.2 and R.sub.3 together contain from 5 to 36 carbon atoms. The process is especially useful for the recovery of metals from leach solutions derived from sulphur-containing ores such as chalcopyrite.
