| 摘 要： | 我国北方某地浸采铀矿山采用CO2+ O2的浸出工艺,通过采用水循环与再利用、反渗透和天然蒸发的综合水处理工艺,最大限度地减少了水的消耗以及废水的产生与排放,并节约了工业试剂.可用于循环和再利用的工艺水包括吸附尾液、饱和树脂冲洗水、沉淀母液和黄饼过滤液.树脂再生废水送反渗透处理,反渗透处理后的浓水连同贫树脂洗涤废水送蒸发池蒸发.

| Abstract: | An in-situ leaching uranium mine located in Northern China uses CO2+O2 leaching process to leach uranium.The consumption of industrial reagent and water,and generation and discharge of waste water are minimized by comprehensive waste water treatment technology with process water recycle,reverse osmosis and natural evaporation.The process water of the mine that can be recycled and reused includes barren fluid,solution washing loaded resin,precipitating mother solution and filtered liquor of yellow cake.Solution regenerating barren resin is treated by reverse osmosis.Concentrated water from reverse osmosis and solution washing barren resin are naturally evaporated. |
