IX Plants

Fixed Bed Ion Exchange:

• Metal recovery from waste streams, i.e. Cu recovery
• Purification of metals, i.e. removing Ni from Co electrolyte
• Precious metals recovery and purification
• Extraction of toxic materials from process streams

Counter Current Ion Exchange:

• Metal recovery from process streams;
  –    Cu/Co/Ni/Zn/U/V/Re/Mo/Au/Bi/Sb recovery.
  –    Enhance product purity using scrub and pre-elution.
  –    U, Re, Ni, Cu products employ these techniques,
• Purification of metals, i.e. removing Ni from Co electrolyte, V from U PLS;
  –    Co/Ni; Ni/Fe; Cu/Fe separations.
• Precious metals recovery and purification.
• Extraction of toxic materials from process streams.
• Fe scrubbing from Ni & CU PLS feeds.
• Rare earths recovery and purification

Test Facilities:

• Laboratory Single Column Testing;
  –    Identifying suitable resins.
  –    Basic loading and kinetic testing.
  –    Basic plant design information.
• Pilot Plant;
  –    Laboratory or site testing.
  –    Confirming data from lab testing.
