• Treatment of NickelCobalt 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
