Treatment of leach liquors containing cobalt and nickel by ZENECA development extractant DS 6001

摘要

A novel class of solvent extraction agents has recently been developed by ZENECA at its Specialties Research Centre in Blackley, Manchester, UK. The chemical and physical properties of one of these reagents appear to offer an elegant route to isolating pure nickel and cobalt streams from mildly acidic aqueous leachates. The performance of the development reagent, DS6001, in both laboratory batchwise tests and mini-rig trials is examined using simulated leach solutions. The data collected indicate that a typical laterite leach liquor may be processed considerably more efficiently using DS6001 than with currently available reagents.
