【Abstract】 In this paper some testing results about the burning of magnesite and the physicochemistry properties of burned magnesite (specific surface area and chemistry activity) were described.The Boron-Magnesium-bearing compound additive is a new type and high quality of additive for iron ore agglomeration.It is comprised of active burned magnesite and boron- containing additives in certain proportion. The effect of using this additive in pelletizing was also reported.更多还原
