Experimental Fluidized-Bed Reduction of New Zealand

W. Shannon cs. - Nama Orang;

Experiment, with a small spouted-bed reactor have shown that fluidized-bed reduction of New Zealand titaniferous ironsands with hydrogen, and with carbon monoxide• containing 50'c hydrogen, can be conducted without sticking, in the temperature ranges 700°-900°c. At 900°c reduction proceeds rapidly to a high degree of metallisation. Fluidized-bed reduction with carbon monoxide is possible, without sticking, in the temperature ranges 600°-750°c, but reduction rates are relatively low. •
Preoxidation of the ironsands increases the rate of subsequent reduction with carbon monoxide and-or hydrogen, the effect of preoxidation being particularly m.irked at the lower reduction temperatures.
Rates of metallisation and gas utilisations in the reduction of titaniferous ironsands have been determined and compared with similar data for a purer grade of magnetite. These comparisons indicate that the impurities present retard the reduction 'of the citaniferous ironsnnds but extend the temperature ranges at which reduction can be effected without sticking.
