Ores unprocessed

Iron ore fines are created as a result of mining, crushing and processing the larger pieces of ore. Iron ore fines are less desirable (and of lower value) as they need to be sintered before they can be utilised, otherwise it will effectively smother the air flow in the blast furnace.

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.
