ABSTRACT:
The present invention relates to a method and apparatus for the continuous countercurrent desorption of targeted materials including metals, non-metals and inorganic and/or organic compounds of thereof, wherein the desorption method is divided to the two modes namely: (I) desorption and (II) re-absorption. The desorption of the target material from the loaded resin using the fresh desorbent takes place in mode (I). According to mode (I) loaded resin moves upwardly in a chamber. According to mode (II) impurities are desorbed from resin and targeted material in solution can be re-absorbed. The resin moves downwardly in another chamber during mode (II). Concentrated eluates, which are suitable for the direct economical recovery of chemical elements and/or compounds thereof, can be produced using the present invention. The apparatus of the present invention includes desorption and re-absorption zones that are configured using a “pipe-in-pipe” construction or a U-shape construction.
