摘　　要：为了解决如何使得麦饭石中微量元素溶出量达到最佳这一问题,采用室内分析方法,研究了麦饭石溶出性能的影响因素,研究发现麦饭石母岩经过风化作用后,原生的铝硅酸盐矿物变成白色细鳞片状绢云母。Na+、Mg2+、Ca2+等离子从硅铝酸盐矿物中析出,K+、CO32-等离子进入矿物内部,这就是麦饭石能溶出大量的常量元素的原因。随着浸泡温度的提高以及对麦饭石进行活化处理等,麦饭石矿物中元素的溶出能力将会得到提高。该研究对麦饭石矿产资源的进一步开发利用具有一定的参考价值和指导意义。In order to solve the problem of how to make the trace elements dissolved performance the best, the dissolved performance affecting factors of medical stone are studied by testing and analyzing in laboratory. The result is that not only the primary aluminosilicate mineral turned into white finely scale sericite after the parent medical rocks underwent weathering, but also the Na^＋, Mg^2＋, Ca^2＋ ions and so on are evolved from aluminosilicate mineral, at that time, the K^＋, CO3^2- ions and so on get into mineral, this is the reason why the medical stone dissolves many constant elements. With soaking temperature longer and actively treating of medical stone, dissolved performance of elements of medical stone mineral will be able to be improved. This work has certain reference value and guiding significance to further exploiting mineral resources of medical stone.
