OutOtec HydrOmetallurgical Nickel PlaNts aNd PrOcesses
Nickel laterite leaching Outotec is continuously testing and developing an optimum atmospheric leaching process for nickel later- ites. In the process, different nickel laterites are leached in several co-current stages in atmospheric reactors, depending on ore mineralogy.

region of Manisa by performing various hydrometallurgical methods under the optimum conditions. This column leach solution of nontronite type lateritic nickel ore was initially neutralized and purified from its basic impurities by a two stage iron removal process under the optimum conditions determined experimentally.
CA2891140C - Hydrometallurgical process of nickel laterite
A hydrometallurgical process for a nickel laterite ore to recover nickel and cobalt from the nickel laterite ore by a High Pressure Acid Leach comprising an ore treatment step, a leaching step, a solid-liquid separation step, a neutralization step, a zinc removal step, a sulfurization-step, and a final neutralization step, which comprises at least one step selected from the following steps B
DEVELOPMENTS IN THE HYDROMETALLURGICAL PROCESSING OF NICKEL
The DNi Process is an atmospheric hydrometallurgical process which is capable of treating all types of nickel laterite ores to produce a number of saleable products. It has been in development
Hydro-Pyro Integration in the processing of Nickel Laterites
Hydrometallurgical process routes are seen to be the future of treatment of the lower grade nickel laterites ores. Hydrometallurgical projects of recent years have focused on HPAL and have been largely unsuccessful economi cally so far, with huge capital cost overruns.
