  • Environmental Guidelines for Nickel Smelting and Refining

    436 Nickel Smelting and Refining cathodes is the most common technology used for nickel refining. Electrowinning, where nickel is removed form solution in cells equipped with inert anodes is the more common refining process used for nickel. Chloride electrolytes are used although sulfuric acid solutions are used more often. Waste Characteristics

  • The DNi Process™ | The DNI Process™ - Direct Nickel

    The DNi Process™ is most efficient for extracting nickel from laterites and the first to treat both of the layers that comprise a laterite deposit in any proportion – meaning better utilisation of the resource. The DNi Process™ is environmentally friendly because almost all the reagent is captured and recycled. Tailings are benign and can ...
