<p>Process comprises treatment with mixts. of hydroxy-oximes and carboxylic acids, the acidity being neutralised with alkali, and the cobalt and nickel extract going for washing and reextraction using controlled pH acid. The organic extract containing nickel goes for reextraction giving an aqueous solution of nickel salt. - A fraction of the organic solution, prior to recycling, undergoes regeneration in contact with an element in the metal state and then with an acid.</p> |
