- W2009059608 abstract "광물찌꺼기에는 다양한 종류의 중금속이 함유되어 있어, 국내외에서 광물찌꺼기로부터 중금속을 제거하기 위해 많은 연구가 이루어졌으나, 중금속을 제거하기에는 여러 가지 문제점과 제약이 따르기 때문에 한계가 있었다. 따라서 이를 해결하고자 본 연구에서는 미립자의 선별까지도 가능한 다중비중선별기(Multi-gravity separator, MGS)를 사용하여 광물찌꺼기에 함유된 비소를 제거하기 위한 비중선별실험을 수행하였다. MGS를 이용하여 비중선별에 의해 비중이 높은 비소를 함유한 광물을 제거하고자 경사각, 세척수량, 광액농도, 드럼의 회전속도, 급광량에 따른 영향을 확인하였다. 실험결과 최적실험 조건인 MGS의 경사각 <TEX>$3^{circ}$</TEX>, 세척수량 5 l/min., 광액농도 30%, 드럼 회전속도 208 rpm, 그리고 급광량 265.24 g/min. 에서 As 제거율과 산출율이 각각 88.21%와 92.25%인 결과를 얻었다. It comtained various kinds of heavy metal in beneficiatian tailing and in order to eliminate the heavy metals, various technologies have been researched, But there are a limits because many problems and restrictions are accompanied. Therefore, in this study, in order to solve this problem, It was performed gravity separation using melti-gravity seperator (MGS) to remove As contained in tailing, which can sort out even the fine particle. It was attempted a study to remove As, which is a kind of heavy metals, by MGS gravity separation and verified the impact by slope, wash water, pulp density, rotational speed and feed rate. In the results of performing gravity concentration under the condition with the MGS slope of <TEX>$3^{circ}$</TEX>, wash water of 5 l/mm, pulp density of 30%, rotational speed of 208 rpm, and the feed rate of 265.24 g/mm, the As removal rate of 88.21% and yield of 92.25% were obtained." @default.
