The processing of magmatic sulfide ores differs from laterites: sulfide ores are crushed in multiple steps to .
Palladium, iridium, and gold in the ores and host rocks of ...The total precious metal tenor of typical Western Australian nickel sulfide ore is similar to that of average Sudbury ore although gold, ruthenium, iridium, and osmium are higher (and platinum may be lower) in the Western Australian ores. Both palladium and platinum are distinctly lower than in average ore from the Merensky Reef.
nickel sulfide extractionAfter producing the nickel matte, further processing is done via the SherrittGordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then, solvent extraction is used to separate the cobalt and nickel, with the final nickel .
