Granulometric control of nickel sulfide precipitate |
摘要 |
A process wherein nickel in an aqueous stream is recovered as nickel sulfide by precipitation in an autoclave with pressurized hydrogen sulfide in the presence of a large quantity of recycled fine nickel sulfide seed material is improved when operated under continuous conditions by introducing into the autoclave a small, controlled quantity of supplemental seed material designed to maintain the seed surface area within required limits.
