Abstract
A heap leach process for the recovery of nickel and cobalt from a lateritic ore, said process including the steps of leaching and/or agglomerating the ore with a lixiviant that includes ferrous ions, wherein the lixiviant is able to liberate cobalt from the cobalt containing minerals within the ore in preference to nickel, to produce a cobalt rich pregnant leach solution relatively free of nickel.
