Abstract

Procedure for the recovery of cadmium from solutions that contain it, especially those obtained in the wet treatment of different minerals or the products of its roasting and also pyritic minerals, especially pyrite ash, from the waters of natural pyrite washing and those from the drains of the mines of said mineral, characterized in that it is added to the cadmium solution, if these do not contain it previously, chloride ion up to concentrations between 0.5 and 2 moles per liter, for the cadmium to form a complex of anionic character, cl3cd-, in whose form it is put in contact with a strongly basic anion exchange resin, which retains it, and from which it is then eluted with an ammoniacal solution, leaving the resin ready for a new cycle.
