| Summary: | In light of fast depleting nickel sulfide ore reserves and increasing demand for nickel, the future of the nickel industry lies in the hydrometallurgical processing of the relatively abundant low-grade nickel laterite ores. The purification of the leach solutions, however, has proven difficult. Hydroxide and oxidative precipitation processes using a variety of reagents were developed for processing synthetic sulfate solutions simulating nickel laterite leach solutions and nickel and cobalt solutions following iron precipitation process. |
