Method for calcified roasting of a vanadium-containing material

摘要

The present invention discloses a method for calcified roasting of a vanadium-containing material, comprising: allowing a raw material and a clinker to contact and react under calcified roasting conditions, wherein, the raw material is a mixture comprising a vanadium-containing material and a calcium-containing material that has not been treated by calcified roasting, and the clinker is a material that has been treated by calcified roasting. With the method disclosed in the present invention, material agglomeration or adhesion to the equipment can be avoided; in addition, the production cost can be reduced since it is unnecessary to add vanadium-extracted tailing and treat the tailing; in addition, the vanadium conversion rate can be improved effectively.
