“…남미의 대표적인 광업 국가인 칠레는 광산의 일반현황과 광산폐기물의 매장량, 금속물질의 농도(57개 항목) 등 주요 특성 정보를 DB화하여 제공하고 있다 (Sernageomin, 2023). 국내의 경우 희유금속의 매장량 및 저품위 등 자원개발 의 낮은 경제성과 한계점으로 인하여 휴•폐광산의 유가금 속 회수 및 개발 가능성을 제안하고 있으며 (Choi, 2004), 실 제적으로 다양한 물리적 선별기술을 적용하여 환경적으로 유해한 금속 및 황화광물을 분리•선별하여 광물찌꺼기의 재활용 가능성을 검토한 연구들도 존재한다 (Chae et al, 1999;Jeong et al, 2006;Oh et al, 2010) 은 모든 시료에서 지각 평균 함량(2.0 mg/kg) 보다 높은 농 도로 확인되었으며, JG(14.5 mg/kg) 7.2배, YP(13.1 mg/kg) 6.5배, SD(5 mg/kg) 2.5배, GR(2.1 mg/kg) 1.1배 순으로 평 가되었다. 몰리브덴(Mo)은 SD(37.4 mg/kg), GR(4.5 mg/kg) 시료에서 지각 평균 함량(1.2 mg/kg) 대비 각각 31배, 3.7배 높은 농도로 검출되었다.…”

Four tailings representative of mineralization types were taken at abandoned metal mines, and 32 elements classified as from critical minerals were analyzed. Among the elements, vanadium (V), bismuth (Bi), manganese (Mn), and antimony (Sb), contained at concentrations exceeding the average abundance of the earth's crust, were examined in terms of their recovery characteristics by heavy liquid and magnetic separations. Although tailings from the Fe-Ti mine contained 1,354 mg/kg of V, improvement of V grade was limited by the separations. Tailings from the W mine with 153 mg/kg of Bi were increased by 3.5 and 6.3 times by concentration by heavy liquid and magnetic separations, respectively. In addition, tailings from the Cu-Pb-Zn mine with 13,756 mg/kg of Mn were concentrated about 1.8 times by heavy liquid separation. Tailings from the Zn mine with 87 mg/kg of Sb were concentration by 1.7 times by magnetic separation. This study promotes recycling through the mineral processing of abandoned tailings.

주제어 : 상동광산, 광물찌꺼기, 부유선별, As AbstractFroth flotation was performed to remove As from the tailing of Sangdong Mine. When the tailings of Sangdong Mine were analyzed by the Standard Method for the Soil Environment Conservation, the concentration of As was found to be at a serious level (282 mg/kg), exceeding countermeasure standard (75 mg/kg). Froth flotation was performed to remove As and preliminary tests were performed to select the reagents. Specifically, froth flotation was performed using collector and frother, KAX and DF250 respectively. An experiment based on pH changes found that the removal rate was highest at pH6. The removal rate of As was highest at agitating rate 1500 according to the agitating rate. In the experiment based on the quantities of KAX added, the removal rate of As was found to be highest at 300 g/ton and was reduced at higher levels than 300 g/ton. An experiment based on pulp density found that the removal rate was highest at pulp density 30%. It was possible to adjust the As level --which exceeded countermeasure standard (75 mg/kg) --to 22.5 mg/kg to satisfy the Warning standard (25 mg/kg), from the results of froth flotation

Froth flotation was performed to study the effect of phosphate addition in the experiment to remove As from tailing of Sangdong Mine. The experiment without Trisodium phosphate (T.S.P) showed that the removal rate of As was 88.7% and weightratio of floating material was 2.52%. By contrast, the experiment with T.S.P showed that the removal rate of As was 92.74% and weight-ratio of floating material was 2.26%. In flotation without T.S.P, the average particle size of float material was 19.34 um and the amount less than 10um was 40.2%. On the other hand, in flotation with T.S.P the average particle size of float material was 176.8 um and the amount less than 10um was 6.5%. The result of X.R.F analysis presented that contents of SiO 2 was 42.74% in float material of the experiment without T.S.P. In contrast, contents of SiO 2 was 29.56% in float material of the experiment with T.S.P.
