Cadmium: processing Metalpedia

Cadmiumis mainly a byproduct of beneficiating and refining of zinc metal from sulfide ore concentrates. Refining of zinc and itscadmiumcontent, can be accomplished by treating the zinc concentrates and/or zinc-bearing secondary materials using either a hydrometallurgical or pyrometallurgical process.

Pyrometallurgical Recovery Of Metals From Electronic Waste

This method is also based onPyrometallurgy. In this method thecadmiumis distilled at high temperature (850-900 degree centigrade) in a reducing atmosphere. Then thecadmiumis chemically leached with the help of sulphuric acid and finallycadmiumis recovered from the leachate by electrolysis (Sequeira & Moffat, 1997).
