The recovery of nickel from high-pressure acid leach solutions using
At the 1996 ALTA Nickel Conference, Cognis introduced the concept of treating nickel laterites (Mackenzie et al., 1996) using a high-pressure acid leach (HPAL) followed by mixed hydroxide precipitation (MHP), ammonia releach of nickel and cobalt and the refining of nickel using LIX ® 84-INS based solvent extraction (SX). In the intervening years this process …
