Nickel Sulfide Versus Laterite : The Hard Sustainability

2009-9-22  Nickel is commonly present in two principal ore types sulfide or laterite ores. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt, and sometimes other precious metals such as gold or platinum and palladium (generally grouped as platinum group metals or PGMs).

Sulfation Roasting of Nickel Oxide–Sulfide Mixed Ore

Sulfation roasting, a common activation technique, is a potential method for cleaner production of nickel from complex low-grade ores. In this study, nickel oxide–sulfide mixed ore concentrate was roasted with the addition of ammonium sulfate under a static air atmosphere, and the roasted products were leached by water, in order to evaluate the extraction of metals.

Sulfide Ore an overview ScienceDirect Topics

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
