Treatment of Nickel-Cobalt Laterites

1. 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 this is that for limonitic ores in particular, the
