摘　　要：本文针对某些矿区卤水中SO42-和Mg2+含量太高以致影响盐质的现象,以自贡大山铺矿区四采卤水为试验对象用较为经济的石灰法进行处理,取得一定效果,可同时去除Mg2+和一部分SO42-;但受石灰自身溶度积的限制不能彻底去除SO42-。若要进一步去除高含量SO42-,还需与其它处理方式相结合,以便通过更经济的处理方式获得理想的结果。In accordance with the phenomenon that extremely high content of SO4^2- and Mg^2＋ in the brine of some mines affects salt quality,the authors make an experiment on the quaternary extraction brine in Dashanpu Mine.The brine is treated with relatively economical lime process with certain effect achieved.Mg^2＋ and part of SO4^2- can be removed simultaneously,however,SO4^2- can not be removed thoroughly due to the restriction of solubility product of lime.In order to further remove high content of SO4^2-,it needs to be combined with other treatment with a view to achieving ideal results with more economical treatment.
