Treatment of Nickel-Cobalt Laterites

Nickel and cobalt can usually be solubilized from laterites using sulphuric acid at atmospheric pressure, just below boiling point. However, this generally requires a massive quantity of acid, which can render the process uneconomic. The main reason for thisPagesis that for limonitic ores in particular, thevery high iron content must be dissolved in order to solubilise the nickel.
