NICKEL RECOVERY FROM A HIGH FERROUS CONTENT LATERITE ORE
摘要
<p>A process for the recovery of nickel and/or cobalt from laterite or partially oxidised lateritic ores having a substantial proportion of the iron present in the ferrous state, said process including the steps of : a) providing a laterite or partially oxidised laterite ore wherein a substantial proportion of the iron present in the ore is in the ferrous state; b) acid leaching the ore to provide a product leach solution containing at least ferrous iron, nickel and cobalt together with acid soluble impurities; and c) recovering the nickel and cobalt from the product leach solution with a selective ion exchange resin in an ion exchange process leaving the ferrous iron and other acid soluble impurities in the raffinate.</p>
