【Abstract】 A new process of vanadium extraction from silica based vanadium ore by oxidation roasting with calcium compounds was studied. This new process is to overcome the difficuties in environmental pollution and low recovery ratio of vanadium. The roasting and leaching principles of the process, the technological flow chart, the technical indexes and its application in production are discussed.更多还原
