Chlorination behaviours of ilmenite, magnetite, and titaniferous magnetite were investigated by means of a thermogravimetric analysis. Magnetite and titaniferous magnetite could be chlorinated readily, while ilmenite was rather difficult. The preferential removal of the iron from ilmenite by selective chlorination was extensively studied by measuring effects of carbon, chlorine flow rate, time, and temperature. Rate equation correlating the results as well as chlorination mechanism was also discussed. |
