While the pressure leach step is similar in all plants, the processes vary considerably in the treatment of the leach solution. The CESL Nickel process for sulphide concentrates has been adapted to treat pressure leach solution from laterite ores and offers an alternative to the existing flowsheets.

Investigators discovered that a steady buildup of zinc accumulated in the solvent phase within the extraction circuit, proportional to the amount of leach liquor treated. The solvent phase zinc analysis increased by wtpct ZnO for each 1,000 gal of pregnant leach liquor purified.
