内容記述 | Heavy metals in sediments after treatment of mine wastewater from Ogoya Mine, Ishikawa Prefecture, Japan, was mineralogically investigated. Acidic wastewater (pH 3.5) which flows out from pithead, contains high concentration of heavy metals. In this mine, neutralizing coagulation treatment is going on using slaked lime (calcium hydroxides: Ca (OH) 2). Core samples were collected at disposal pond to which treated wastewater flows. Mineral assemblages and chemical compositions of core samples were analyzed. X-ray powder diffraction (XRD) analyses indicate that upper parts of cores are rich in calcite, whereas deeper parts of cores are rich in gypsum and ettringite. Smectite with heavy metals are found in 87-90cm of core samples. Scanning Electron Microscopy (SEM)-Energy Dispersive X-ray analyses (EDX) and Electron Probe Micro Analyzer (EPMA) show that heavy metals, such as, Fe, Mn, Cu and Zn are concentrated in calcite, gypsum, ettringite, and clay minerals. The results indicate that heavy metals in wastewater are mineralogically fixed in solid phases of calcite, gypsum, ettringite and smectite. | |||||
