Metal values are extracted from aqueous solutions of metal salts containing halide or pseudo halide ions by pyrimidine, pyrazine or pyridazine derivatives bearing the substituent --(C.dbd.O.X).sub.n 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 1 to 36 carbon atoms and R.sub.2 and R.sub.2 together contain from 1 to 36 carbon atoms. The molecule as a whole contains from 5 to 36 alkyl carbon atoms and may carry further optional substituents. The process is especially useful for the recovery of metals from leach solutions derived from sulphur-containing ores.
