탄소존재하에서 이산화황에 의한 함티탄 자철광의 황화반응(I)
Sulfidization of Titaniferous Magnetite with Sulfur Dioxide in the Presence of Carbon(I)
탄소 존재하에서 이산화황을 황화제로 한 함티탄 자철광의 황화반응에 대하여 연구하였다. 본 연구에서는 반응온도, 반응시간, 함티탄 자철광에 대해 첨가되는 탄소의 무게비, SO2 가스의 유량 그리고 함티탄자철광의 입도 등의 변수가 황화반응에 미치는 영향을 검토하였다. 또 황화된 함티탄자철광으로부터 합성 rutile을 제조하고자 하였다.
본 황화반응의 적당한 반응조건은 반응온도 : 800 ℃, 반응시간 : 1 h, 함티탄 자철광에 대해 첨가되는 탄소의 무게비 : 0.7, 함티탄자철광의 입도 : -150 mesh, SO2 유량（반응관크기 : 내경=2.8 ㎝, 길이=100 ㎝） 100 ㎤/min였으며 황화된 반응물을 1 M HCl로 침출하여 제조된 합성 rutile은 X-선 회절분석 결과 rutile임이 확인되었으며 이의 함량은 82.15 % TiO2로 나타났다.

The sulfidization of titaniferous magnetite（Soyonpyongdo, Korea） with sulfur dioxide in the presence of carbon was studied.
The study of this reaction included reaction variables such as reaction temperature, time, weight ratio of added carbon to titaniferous magnetite, flow rate of sulfur dioxide, and particle size of titaniferous magnetite.
An attempt was made to produce synthetic rutile from titaniferous magnetite by the sulfidization.
The optimum conditions for the reaction were that reaction temperature was 800 ℃, reaction time, 1 h, weight ratio of added carbon to titaniferous magnetite 0.7, particle size of titaniferous magnetite -150 mesh, and SO2 flow rate （reactor size : ID =2.8 ㎝, length = 100 ㎝） 100 ㎤/min. The synthetic rutile prepared by leaching the sulfidized product with 1 M HCl was identified as rutile by the x-ray diffraction analysis and was found to contain 82.15 % TiO2.
