Kinetic Study of Formation of Sodium Titanets by Roasting of Soda Ash and Ilmenite Ore Concentrate

摘要

In the present paper, the roasting of soda ash and rosetta ilmenite ore concentrate briquette in the temperature range of 700-900°C was investigated and the kinetics of formation of sodium titanate was studied. The kinetics of roasting of ilmenite with (35%) soda ash briquettes showed that the reaction is diffusion-controlled and the energy of activation is 135 kJ/mol.
