Abstract Solid state reduction of raw titaniferous magnetic ore, its sinter, and pellets with H_2 and CO have been studied at various temperatures. It has been found that pelletization remarkably increases the reducibility of the raw ore. Preliminary studies of the rate and mechanism of reduction of the raw ore indicate that the rate of reduction is controlled by surface reaction and the reaction is of the first order. At temperatures above 590℃, the apparent activation energy is 14,600 cal/mol for CO and 14,000 cal/mol for H_2; while it is 16,000 cal/mol for CO at temperatures below 590℃.
