description The invention relates to the field of resource recovery, and discloses a method for separating or recovering molybdenum and chromium from a sample containing molybdenum and chromium, and the method comprises the following steps: (1) mixing waste salt, a solvent and a coagulant, carrying out coagulation pretreatment, and carrying out solid-liquid separation to obtain an alkaline clear solution; (2) absorbing Mo and Cr in the alkaline clear liquid by using resin; (3) desorbing the resin to obtain a desorption solution containing Mo and Cr; (4) adsorbing the desorption solution containing Mo and Cr by using active carbon to obtain active carbon produced water containing Cr; (5) desorbing the adsorbed activated carbon to obtain a desorption solution containing Mo; and (6) optionally, the activated carbon produced water and the Mo-containing desorption solution are subjected to precipitation treatment, and a Cr-containing product and a Mo-containing product are obtained. By adopting the method, the chromium and th
