摘要
针对原地浸矿新工艺及池浸工艺生产稀土的不同环境影响 ,进行了龙南、寻乌两试验矿块的水、土壤环境质量监测 ,指出原地浸矿新工艺对水、土壤环境质量影响甚小。经测算 ,原地浸矿新工艺的环境代价为每吨氧化稀土产品可创效益3300~3800元 ,从环境经济效益角度 。
Focus on the different environmental impact in the process of producing RE between in situ leaching and pond leaching,the quality monitoring on water and soil were done in the experimented mineral field of Longnan and Xunwu.The monitoring results showed that the impact of in situ leaching on natural environment was very little but the impact of pond leaching on environment was very greatly.In situ leaching can bring good economic profits in producing RE oxides from preventing the loss of water and erosion of soil,so we must spread this leaching technology.
