The mineral and chemical compositions,occurrence and distribution of the valuable elements,the structure and tectonics of vanadium slag were characterized by X-ray powder diffraction,optical microscope,X-ray fluorescence,scanning electron microscopy and energy dispersive spectrum,aiming to provide a theoretical foundation for efficient and clean utilization of vanadium slag.It is suggested that the vanadium slag is composed of vuorelainenite,fayalite,augite,metallic iron and a small amount of quartz. The crystalline grains of vuorelainenite are fine and encompassed by the silicates,difficult to be separated and enriched physically.The main valuable elements are Fe,V and Ti with considerable Cr and Mn.V and Cr primarily exist in vuorelainenite while Fe,Ti and Mn are distributed both in vuorelainenite and silicates.Hence,to realize an efficient recovery of vanadium slag,simultaneous utilization of vuorelainenite and silicates minerals in the slag should be taken into consideration.
