Abstract
A process for the recovery of nickel and/or cobalt from a nickel and/or cobalt containing solution comprising: (i) contacting the nickel and/or cobalt containing solution with metallic particles of at least one metal that is more electronegative than nickel and/or cobalt thereby enabling a cementation process to occur between the nickel and/or cobalt in the solution and the metallic particles to produce a nickel and/or cobalt cementate; and (ii) separating the nickel and/or cobalt cementate from the metallic particles thereby producing a slurry including nickel and/or cobalt cementate.
