ABSTRACT:
The method for recovering metals of Groups V-VI of the periodic system from solutions and pulps according to the present invention is effected by means of a selective ion-exchange resin which is the reaction product between a polyhydric phenol with formaldehyde with a specific surface area of from 50 to 600 m.sup.2 /g, pore volume of from 0.2 to 2.3 cm.sup.3 /g, content of hydroxy groups of at least 11.3 mg-equiv/g.
