Analysis of the first-stage leach process at Inco Ltd. s

This residue is treated batchwise in two successive leaching stages. The non-oxidative First-Stage Leach (FSL) process extracts the vast majority of the Ni Co Fe and As values. The Second-Stage Leach (SSL) process comprises the aqueous pressure oxidation of a predominantly Cu₂S feed under acid-deficient conditions.

Pressure acid leaching of nickel lateriteUBC Library

Pressure acid leaching is an acceptable process for the treatment of nickel laterites. This process offers many advantages such as low energy consumption low capital cost and high nickel and cobalt recoveries. The dissolution process is coupled to selective thermal hydrolysis of iron and aluminum.

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.

Prior to the development of the Isa Process technology the standard approach was to use a starter sheet of high-purity copper as the initial cathode. These starter sheets are produced in special electrolytic cells by electrodeposition of copper for 24 hours onto a plate made of copper coated with oil (or treated with other similar face-separation materials) or of titanium.
