Latest Patents

Kerfoot's latest patents focus on a hydrometallurgical process for the recovery of nickel and cobalt values from a sulfidic flotation concentrate. This innovative process involves forming a slurry of the sulfidic flotation concentrate in an acid solution. The slurried flotation concentrate is then subjected to a chlorine leach at atmospheric pressure, followed by an oxidative pressure leach. After liquid-solids separation and purification of the concentrate, which results in the removal of copper and cobalt, the nickel-containing solution is directly treated by electrowinning to recover nickel cathode.
