有机酸对低渗透砂岩铀矿溶蚀作用试验研究
Experimental Study on the Dissolving Effect of Organic Acids on Low Permeability Sandstone Uranium Ore
摘要
Abstract
In order to explore the dissolving effect of microbial metabolic organic acidson low permeability sandstone uranium ore,this paper investigates the dissolution effect of four microbial metabolic organic acids,citric acid,succinic acid,acetic acid,and lactic acid,on low permeability sandstone uranium deposits using a low permeability standstone uranium ore of Xinjiang as the research subject.X-Ray Diffraction examination of rock samples before and after dissolution was used to investigate the dissolving features of organic acids in low permeability sandstone uranium deposits.The results demonstrate that the dissolving quantity of organic acids in sandstone uranium ore samples is:citric acid>succinic acid>acetic acid>lactic acid;Despite citric acid has a highter overall solubili-ty,the data of X-Ray Diffraction show that the dissolution of quartz and calcite by succinic acid is 0.6%and 3.6%higher than that by citric acid,respectively.Albite content re-duces as succinic acid dissolves sandstone uranium ore,whereas citric acid has the reverse effect.关键词
