Nickel Sulphide Process Flow

Nickel from sulfide ores Big Chemical Encyclopedia

Sulfide ores are first roasted to convert sulfides to oxides and then reduced by heating in hydrogen and carbon monoxide water gas The crude metal is caused to react with carbon monoxide at 50°C producing Ni CO 4 which is subsequently decomposed at 180 to 200°C

nickel processing Extraction and refining Britannica
