ABSTRACT:
Process for the removal of cadmium from an aqueous, acidic, cadmium containing solution by electrodepositing the cadmium on conducting particulates present in a packed or fluidized bed cathode compartment of an electrolysis cell in which the aqueous, acidic, cadmium-containing solution contains phosphoric acid. The process is of particular interest for the removal of cadmium from phosphoric acid solutions which are obtained during the production of phosphorus-containing fertilizers from phosphorus rock.
