A process in which high nickel and low iron dissolution from saprolite ore can thus be devised by leaching the ore with acid concentrations below about 50 g/l. The nickel extraction as a function of time is illustrated in FIG. 3, which shows that the rate of nickel extraction is a strong function of the sulfuric acid concentration.
