Ilmenite를 木炭과 混合하여 鹽素가스로 鹽素化 할 경우 良好한 收率로서 四鹽化티타늄을 얻을수 있는 好適條件에 關하여 實驗檢討한 結果, 다음과 같다. Ilmenite 및 木炭의 粒度를 各各 -200 mesh 및 100∼200mesh, 團鑛의 크기 6∼10mesh, Ilmenite와 木炭의 混合重量比 1:0.6, 鹽素가스流量 750㏄./min, 鹽素化溫度 800℃가 적당하다. 以上과 같은 條件하에서 40分間 鹽素化시킨 結果 99% 以上의 티타늄이 鹽素化 되였다.

The optimum condition for recovering titanium from Korean ilmenite by chlorination process was studied as a function of particle size of ilmenite and charcoal, ratio of charcoal to ilmenite, size of briquette, chlorine flow rate, chlorinating temperature and chlorinating time. It was found that more than 99 percent of titanium was chlorinated when 6-8 mesh briquette made from 1 part of -200 mesh ilmenite and 0.6 part of 100-200 mesh charcoal, was decomposed with chlorine of 750 ㏄./min. at 800℃ for 40 minutes.
