ABSTRACT:
Disclosed is a process for the precipitation and separation of cadmium sulphide from the raffinates derived from phosphoric acid purification by treating the cadmium containing streams of the raffinates with a H.sub.2 S containing solvent phase in a mixing-settling apparatus, by separating the raffinate phase from the cadmium sulphide containing solvent phase and by separating the precipitated cadmium sulphide from the solvent phase. By operating this process it is possible to remove cadmium in a simple manner from the raffinates since their inherent properties don't influence the precipitation and separation of cadmium sulphide.
