1987-5-1  For example, in the 1960's, nickel produced from laterite made up 10--15% of the world nickel production, but by 1980 this figure had gone up to about 30%. This is due to the fact that during the past twenty years there has been a remarkable increase in nickel production in Japan, where laterite is used as raw material for nickel smelting.

Treatment of Nickel-Cobalt Laterites

2020-8-19  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.
