    • A process for recovering mercury from a mercury-contaminated material, comprising a step making use of a lixiviating system comprising iodide, iodate and tri-iodide ions in an effective amount in order to desorb and complex mercury from the said material.
      The process may be performed in apparatus for recovering a heavy metal from a heavy metal-contaminated material, having:

      a cathode compartment (1) comprising a cathode (2) and an ion-permeable housing (3) for containing a cathode solution (4),
      an anode compartment (5) comprising an anode (6) and an ion-permeable housing (7) for containing an anode solution (8),
      a cathode recipient (9) for supplying the cathode solution to the cathode compartment (1),
      an anode recipient (10) for supplying the anode solution to the anode compartment (5),
      a device for isolating, from the anode solution (8), a set of ions electrokinetically transported from the cathode solution (4) and a heavy metal complex electrokinetically transported from the heavy metal-contaminated soil, and
      a device for recycling the ions isolated from the anode solution (8) back to the cathode solution (4).
