process used for nickel. Chloride electrolytes are used although sulfuric acid solutions are used more often. Waste Characteristics Air emissions Sulfur dioxide (SO2) is a major air pollutant emitted in the roasting, smelting and converting of sulfide ores (nickel sulfide concentrates contain 6-20% nickel and up to 30% sulfur).
found in copper and nickel concentrates as well. One considers a “typical” copper concentrate as having about 25+% copper and some minor quantity of impurities, preferably rich in precious metals. In practice, smelters purchase all variety of concentrates and
Using nickel flash smelting technology it is possible to process sulfide nickel concentrate and produce nickel matte and slag in a relatively efficient process. Any materials resulting as smelting and converting slags are recirculated in the electric furnace and recovered where possible as nickel matte. Nickel (Ni) is a silvery-white, hard metal.
