Thermal studies were performed on the segregation roasting of pure nickel sulphate. The reaction path was found to be the same as for oxide segregation, although some deviation was observed during product formation, where a metallic nugget was obtained as the end product. The nickel content in the metallic nugget has been analysed at 74% (remainder sulphur). The optimum reaction temperature appears to be 1100°C; with 10% CaCl 2 + 10% charcoal addition (by weight); after roasting for 30 min, it is possible to extract a product containing 97% metallic nickel with 3% sulphur.The authors are at
