<p>Separation on resin by multicolumn sequential selective retention to separate an ionic metal derivative from a leaching solution containing ionic metal derivative, by passing the solution on a fixed resin bed and comprising at least three areas, means for liquid flow, which is arranged between adjacent areas and between the last and the first area, where the process comprises several sequences, in which each sequence comprises at least one step comprising adsorption step, a rinsing step, and a desorption step, implemented optionally simultaneously, is claimed. Separation process on resin by multicolumn sequential selective retention to separate an ionic metal derivative from a leaching solution containing ionic metal derivative, by passing the solution on a fixed resin bed and comprising at least three areas, means for liquid flow, which is arranged between adjacent areas and between the last and the first area, where the process comprises several sequences, in which each sequence comprises at least one step comprising adsorption step, a rinsing step, and a desorption step, implemented optionally simultaneously, and each following sequence is carried out by moving of fronts in areas towards downstream in same increment before periodic shifting of points for introduction and extraction, is claimed.</p> |
