| description | A process for the recovery of nickel and cobalt from a nickeliferous oxidic ore by heap leaching and/or atmospheric agitation leaching, the process including the steps of: mixing a sulfur containing reductant selected from reductants that do not include copper into a nickeliferous oxidic ore; leaching the reductant/ore mixture with an acidic leach reagent to produce a pregnant leach solution including nickel, cobalt, iron substantially in a ferrous form and other acid soluble impurities; and recovering the nickel and cobalt from the pregnant leach solution. |
