Evaluation of the properties of the CaCO3CaO system for metallurgical use

The principal goal of this work, is to make a preliminary and comparative study on the physical chemistry, structural and thermal properties of the metallurgical lime production using experimental, and in some cases industrial measurements. This is important, because the characterization of the CaCO3CaO system, predicts the dissolution grade of the lime on the slag solution in the steel making. The mineral is located on the border of Michoacan (Lazaro Cardenas)and the Guerrero states (La Union) Mexico. This study evidences limited properties of this lime, which is due to the thermal and physical chemistry behaviour of the obtained results of this material. However, it is necessary to make a study in the future about the kinetic behavior during decomposition. This is necessary because it is important to obtain an increase in the basic oxides concentration and a decrease in the loss of ignition, which is important for the competitive lime production.
