Abstract

Email to a Friend
A new solvent extraction process for the separation of cobalt, copper and zinc from nickel sulphate process streams has been developed. It involves selective extraction of these elements with a quaternary ammonium thiocyanate dissolved in an aromatic diluent. The chemical principles of this process have been investigated and are described, together with background physico-chemical data relating to the use of this solvent. Long-term testing in a continuous "mini-plant" circuit gave high-purity nickel and cobalt products (Ni/Co —200011 and Co/Ni ~1000/1 respectively).
