For sulfide ore processing, nickel has to be separated from the iron present in the sulfide concentrate. This is conventionally done in both the smelting and converting stages. To aid iron rejection in the smelting stage, the concentrate is first partially roasted to oxidize the iron sulfide. This is done either in a multiple hearth roaster or ...
