地浸铀矿山氮系污染物的某些行为研究
Study on several behaviours of nitrogen-series pollutants in in-situ leach mine
摘要
Abstract
As an oxidant in in-situ leach of uranium and elute of saturatedresin, nitrate has been successfully applied to several mines in our country. But the residual NO-3 in ledge and its degradation products NO-2 and NH+4 are all pollutants, which are closely confined by environmental laws. So how to remove them from ledge effectively and to prevent the subsoil water from being polluted has become a problem, to which some mineral enterprises and departments of environment pay attention. Our object is to learn the situation of NO-3's consummation, accumulation and degradation by theoretical and experimental study on extraction solution from simulating experiment and production field. The research shows that NO-3's accumulation originates principally from the initial stage when NO-3-resin absorbs uranium from extraction solution,and its main degradation product is NO-2.关键词
