Nickel-Cobalt Separation - Innovation Metals Corp

Introduction Following the initial development of IMC's RapidSX™ process for the separation of rare-earth elements (REEs), the company turned its attention to the separation of nickel (Ni) and cobalt (Co) from a pregnant leach solution (PLS) produced from a 'real-world' bulk sample of Ni-laterite ore. The testing was completed first at the bench scale, and […]

Autoclave Leaching of Copper Nickel Matte

The matte was preleached at atmospheric pressure to selectively extract 20 pct of the nickel, and the undissolved solids were referred to as the matte residue. Autoclave leaching of the matte residue extracted over 95 pct of the nickel, copper, and iron. The remaining leach residue in the autoclave contained over 100 oz of precious metals per ton.
