초록

염소화에 의한 텅스텐 추출 공정의 공업화를 위해 유동층 반응기에서 회중석의 염소화반응이 조사되었다. 본 실험의 모든 결과는 텅스텐 성분이 유동충 반응기에서 성공적으로 염소화됨을 보여주었다. 본 실험의 적정 조건은 다음과 같다. : 반응온도 900℃, 반응시간 : 20 min, 염소가스 유속 : 13.2cm/sec 그리고 회중석에 대한 petroleum coke의 무게비 : 0.2 또한 회중석과 petroleum coke의 평균 직경은 각각 150.5㎛ 그리고 750.9㎛이다. 이러한 조건하에서 회중석 중의 텅스텐 성분이 95% 이상이 염소화되었다.

Chlorination of tungsten from scheelite ore in a fluidized bed reactor has been investigated to develope tungsten extractive metallurgical process by the chlorination. All of the results in this experiment showed tungsten component could be sucessively chlorinated in a fluidized bed reactor. The proper conditions are as follows ; reaction temperature 900℃, reaction time : 20min, Cl₂ gas velocity : 3.2cm/sec and petroleum coke-to-scheelite ore weight ratio : 0.2. Also the mean diameters of scheelite and petroleum coke were 150.5 ㎛ and 750.9 ㎛ respectively. Under these conditions, over 95% of tungsten component in scheelite was chlorinated.
