Roasting and Induration Mechanism in Magnesia Pellet

Magnesia pellets have become a major trend in the development of the pellets in the future due to its good metallurgical performance.However,problems such as low strength and high demands for roasting process parameters are existing for magnesia pellets.Therefore,it is of important practical significance to study roasting and induration mechanism and then improve process of magnesia pellets.The recent development of roasting and induration mechanism of magnesia pellets and effects of Mg’s source,ratio,process parameters,mineral composition and microstructure on the metallogenic mechanism and metallurgical properties of magnesium acid pellets and magnesian flux pellets were systematically reviewed in this paper,for the purpose of providing basic data and the reference for further promoting magnesia pellet.
