Abstract

To construct the standard methods for evaluation of physicochemical characteristics of tailings in Korea, specific gravity, paste pH, grain size, mineral compositions and heavy metal concentrations of total 26 tailings from 21 metallic mines were analyzed. Specific gravity of tailings ranged from 2.61 to 4.31 (avg. 3.04), and sand and silt grain were dominant in the tailings. Ranges of paste pH were 2.1-9.5 in tailings (7.1-9.2 at magmatic, skarn and hydrothermal replacement deposits and 2.1-9.5 at hydrothermal vein deposits). Additionally, hydrothermal vein deposits could be reclassified into three categories: (1) paste pH>7.0, (2) 4.0

광물찌꺼기의 특성평가 방법의 표준화를 위하여 21개 광산을 대상으로 총 26개의 광물찌꺼기를 채취하여 광물찌꺼기의 비중, paste pH, 입도, 광물조성 및 중금속 함량을 분석하였다. 광물찌꺼기의 비중은 2.61-4.31(평균 3.04)의 범위를 보이며, 입도분포는 모래와 실트의 함량이 우세한 것으로 나타났다. 광물찌꺼기의 paste pH는 2.1-9.5의 범위를 보이는데, 정마그마광상, 스카른광상 및 열수교대광상의 경우에는 7.1-9.2, 그리고 열수맥상광상의 경우에는 2.1-9.5의 분포를 보인다. 열수맥상광상 유형은 paste pH에 따라 paste pH>7.0, 4.0
