ABSTRACT:
The metal content of nickel-cobalt mixed sulfide slurries is recovered by atmospheric oxidation leaching, thereafter removing dissolved copper by metathesis with further mixed sulfide feed, treating the filtrate after liquid-solids separation with ammonia to selectively precipitate cobalt, separating the cobalt precipitate and working up the resulting filtrate to recover nickel.
