Abstract

A slurry of iron oxide solids containing dissolved nickel and/or cobalt is treated to separate those metal(s) from the slurry. The treatment includes controlled precipitation of the sulphides of the metal(s) which is effected by contacting the slurry with calcium or barium sulphide or both to precipitate nickel and/or cobalt sulphides. The precipitated sulphides are separated from the treated slurry by flotation for which suitable collecting agents include sulphyaryls, dithiophosphates, thionocarbamates, and dithiocarbamates and suitable frothing agents include methyl isobutyl carbinol and polypropylene glycol methyl ether.
