Mintek has developed a leaching process that solubilizes the nickel, copper, and cobalt, while rejecting the iron and any sulphur into the solid residue (by decreasing the pH appropriately). The resulting solution can be processed further to separate the cobalt, nickel, and copper from each other via conventional technology.
Nickel | Water Solutions
Nickel is most frequently found in sulfidic ores and nearly always mixed with copper, cobalt, zinc, iron, and other metals. While solvent extraction (SX) can be used to recover nickel, novel selective ion exchange (IX) resins are making it possible to isolate and purify nickel at lower cost and in more environmentally sustainable ways.
