Kinetic regularities of ferruginous laterite carbothermal reduction in the Mina Marti ore body
Keywords:
Carbothermal reduction, ferruginous laterite, metallized, carbon, activation energyAbstract
The reduction of ferruginous lateritic mines under non-isothermal conditions in Nicaro was analyzed using pure carbon, anthracite carbon and carbon fine coke as reducing agents. A Derivatrografh Q-1500D machine which operates at heating temperatures of up to 1 200 0C was used for the thermogravimetric analysis. The use of pure carbon resulted in a variation of the apparent activation energy from 10 kJ/mol to 70 kJ/mol, indicating that the process is controlled by a chemical reaction.Downloads
