Zusammenfassung:Process for the Extraction of Metal Values Using Hydrocyclic Compounds Containing Two Nitrogen Hetero-Atoms and Novel Metal Extractants Metal values are extracted from aqueous solutions of metal salts containing halide or pseudo halide ions by pyrimidine, pyrazine or pyridazine derivitives bearing the substituent -(C=O.X)n where X is the group -OR1 or -NR2R3 and n is 1, 2 or 3. R1 is a hydrocarbyl group containing from 1 to 36 carbon atoms and R2 and R2 together contain from 1 to 36 carbon atoms. The molecule as a whole contains from 5 to 36 alkyl carbon atoms and may carry furter optional substituents. The process is especially useful for the recovery of metals from leach solutions derived from sulphur-containg ores.
