Investigating the Mineralization Characteristics of the Cold Treatment Cake of the Leadand Zinc Factory in Recovering Cadmium from it

There is more than ۲۰% cadmium in the cold cadmium purification cake resulting from zinc processing,and by using ore dressing and acid leaching techniques, pulp with ۷۵% cadmium content can be obtained. Thefilter cake is dried at a temperature of ۸۵-۱۰۰ degrees Celsius for ۳ hours, then the cold filtration cake reachesa particle size below ۲۰۰ mesh. By determining the degree of liberation and acid leaching, its cadmium can beenrichment.
