【摘要】：选择赣南典型稀土矿区,即寻乌(以轻稀土为代表)、安远(以中稀土为代表)和龙南(以重稀土为代表)为研究区域,于生产期和停产期(停产后半年)分别采集了矿区上游、矿区淋滤废水、矿区山泉水、生活用井水、近矿支流、矿区下游等地表水共90件,分析了溶解态稀土元素在离子吸附型稀土矿区周边地表水中的含量、空间分布特征及影响因素。结果表明:稀土矿的开采对矿区周边地表水中DREE含量影响较大。此外,水粒作用、区域地质背景与风化作用、水化学因素都是影响离子吸附型稀土矿区周边水体DREE行为的主要因素。矿区周边地表水中稀土含量高是我国离子吸附型稀土矿山开采引发的特殊问题。
[Abstract]:The typical rare earth mining areas in south Jiangxi, namely Xunwu (represented by light rare earths), Anyuan (represented by middle rare earth) and Longnan (represented by heavy rare earth), were selected as the study areas. The upstream of the mining area was collected during the production period and the shutdown period (half a year after the shutdown), respectively. A total of 90 surface water samples, such as leaching wastewater, mountain spring water, living well water, near ore tributaries and the lower reaches of the mining area, were used to analyze the content of dissolved rare earth elements in the surface water around the ion adsorbed rare earth mining area. Spatial distribution characteristics and influencing factors. The results show that the mining of rare earth ore has a great influence on the DREE content in the surface water around the mining area. In addition, water particle action, regional geological background, weathering and hydrochemical factors are the main factors that affect the DREE behavior of the water around the ion adsorbed rare earth mining area. High rare earth content in surface water around mining area is a special problem caused by ion adsorption rare earth mining in China.
