FIELD: process engineering.
SUBSTANCE: invention may be used in hydrometallurgy. Proposed invention allows separating such metals as uranium, nickel, copper and cobalt present in liquid wastes of ore leaching. Solution containing metal ions is forced through stationary layer of resin, Particularly, through, at least, three zones. Note here that solution drive appliances are arranged between adjacent zones and between last and first zones. Proposed method comprises several sequences, each comprising, at least, one step selected from steps of adsorption, washing and desorption. Every next sequence is performed by shifting fronts into zones downstream of circuit with identical increment unless cyclic shift of inlet and discharge points.
EFFECT: optimised amounts of components, higher efficiency.
