Abstract
본 연구는 무산소성분위기에서의 열분해 및 침출방법에 의해 비소함유황화광으로부터 비소 및 황분을 회수할 수 있는 무공해의 공정에 대한 기초자료를 얻고자 하였다.
질소 기류중에서 열분해반응의 적당한 조건은 반응온도 500 ℃, 반응시간은 광물시료 1 g에 대해 3 min, 광물시료의 입도는 -140 mesh였다. 그리고 2차적인 처리인 침출공정의 적정조건은 침출온도 99 ℃, 침출액량은 열분해생성물 1 g에 대해 50 ml의 H2O, 침출시간 60 min이었다.
위의 적정조건하에서 처리된 최종생성물의 As2O3의 함량은 98.21 %이며 이의 X-선회절분석 결과는 arsenolite로서 확인되었다.

This study was carried out to find a new nonpollutant process for the extraction of acrsenic and sulfur component from arsenic bearing sulfide ore by means of the inert roasting and water leaching.
The proper conditions for the inert roasting of arsenic bearing ore were that roasting temperature : 500 ℃, roasting time : 3 min per lg ore and partcle size of ore :-140 mesh under N2 atmosphere.
The optimum conditions for the water leaching of the inert roasting product were that leaching temperature : 99 ℃, amount of water : 50 ml per lg inert roasting product and leaching time : 60 min.
The analyses of the final product through the both treatments under the above mentioned conditions showed that the content of As2O3 was 98.21 % and the x-ray diffraction pattern was identified as arsenolite.
