摘要 |
An extraction process is described for the selective separation of bivalent metal ions belonging to the group Cu, Co, Ni and Zn in aqueous solution of Cu- and Ni-ions, Cu- and Zn-ions or Cu- and Co-ions, wherein there is used as the extraction medium one or more unsaturated fatty acids, optionally in solution and/or in admixture with saturated fatty acids and an aliphatic oxime.
