초록정보

Deposits of titaniferrous magnetite ore occurring in Korea are estimated to be seven million tons. To obtain pig iron and titania-enriched slag, pellets made of ground ore, coke, and soda ash were smelted in arc-smelting furnace. Magnesium and calcium content present in the slag causes problems such as agglomeration during the fluidizing operation. To remove the impurities from the slag, a series of testes were carried out on sulfation of the slag with $SO_2$ and $O_2$, followed by leaching the impurities in the sulfated slags. The variables studied were concentration of $SO_3$, sulfation temp., particle size, and content of $Na_2O$ in the slag. The experimental results are summarized as follows: 1. The effect of $SO_3$ concentration on the reaction rate was not significant in the range of 0.1 to 0.45 of $^P{SO_3}$. 2. The sulfation rate of titania slag was mainly governed by the migration of magnesium ion in the sulfate layer. 3. Reaction constant, $k_s$, was intensively affected by the oxides of the alkali metals present in the titania slag.
