This paper describes the experimental findings of the extraction of nickel and cobalt by high pressure acid leaching (HPAL) of a refractory limonitic nickel laterite ore from the Gördes region of Manisa in Turkey.

Pressurised leaching is one of several leaching methods.. Pressure leaching is the chemical dissolution of soluble minerals within a solid ore or concentrate carried out at elevated pressures and giving rise to a solution containing metals to be recovered.

Abstract A review of the literature over the past 30 years on the processing of nickel laterites by high temperature acid leaching has been carried out to provide a better understanding of the mineralogy, leaching process chemistry and effect of operating conditions on nickel recovery, residue properties and scaling.

The high pressure acid leach (HPAL) experiments were conducted with nontronitic and limonitic types of Gördes lateritic nickel ore, respectively.
