摘要： 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-OR, or-NR 2 R 3 and n ist 1, 2 or 3. R, is a hydrocarbyl group containing from 1 to 36 carbon atoms and R 2 and R 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-containg ores.

摘要： Metal values are extracted from aqueous solutions of metal salts containing halide or pseudo halide ions by pyridine derivatives containing the substituent -(COX) A where X is the group-OR, or -NR 2 R 3 and n is 1,2 or 3. R, is a hydrocarbyl group containing from 5 to 36 carbon atoms and R 2 and R 3 are hydrogen or a hydrocarbyl group wherein R 2 and R 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.
