Document Type and Number:
Japanese Patent JPS5421905
Kind Code:
A
Abstract:
The invention relates to the re-extraction of a metal from an organic extraction solution in which the metal is present as a metal chloride complex bonded to an extractant. The organic extraction solution is contacted with an aqueous solution, to transfer metal ions and chloride ions to the aqueous solution. Sulphuric acid is added to the aqueous solution, which is subsequently heated to drive off hydrogen chloride and water. Metal sulphate is removed from the acidified aqueous solution.
