| Abstract: | Through elementary geophysical prospecting, chemical exploration and geological exploration, there are above 100000 t Mo reserves in Wenquan Wushan, Northwest China. Presently, the molybdenum mine has gone deploitation and construction. Data from drillings indicated many associated elements such as Cu, Pb, Zn, etc. with Mo. Through complete water quality analysis, we found water here comes up to drinking-water standard. This paper investigated the environmental geochemistry characteristics and evaluated water quality in mine field under existing conditions, which may present reference for forecasting the trends of environmental pollution change, underwater environmental monitoring and protection after exploitation. In exploitation of mineral areas, the surroundings of ore areas and groundwater environmental quality are affected correspondingly. The paper analyzed benefication process and tailing disposal process, and consequently, predicted pollution sources, pollution pathway and post-effect that may come along. Also, the interactions between water and rocks with human activity are discussed. |
