摘　　要：运城盐湖属于硫酸钠型内陆湖泊,无机盐资源丰富,主要含有Na^+、Mg^2+、Cl^-、SO4^2-离子。本文结合南风化工无机盐类产品梳理运城盐湖化学资源--无机盐的开发历程,介绍芒硝、元明粉、硫化碱、硫酸钡以及硫酸镁等生产情况,针对现存市场竞争激烈、环保限产停产、开采不平衡导致产量逐年下降的难题,提出精深加工、注重环保、平衡开发等思路,企业可通过大力研发高附加值产品,改善工艺,延伸产业链提高盐湖无机盐资源的综合利用水平。Yuncheng Salt Lake is a type of sodium sulfate inland lake who is rich in inorganic salt resources and mainly contains Na+,Mg2+,Cl-,SO42-ions.This paper presents the development process of inorganic salt products of Yuncheng Salt Lake,introduces the production process of Glauber's salt,Yuanming powder,alkali sulfide,barium sulfate and magnesium sulfate in Nafine Chemical Industry Co.,Ltd.This paper proposes possible solutions to the problem that inorganic salt production decrease year by year due to fierce market competition,output restricted by environmental protection requirements and unbalanced exploitation,aiming to improve the comprehensive utilization level of salt lake resources by vigorously researching and developing high value-added products,improving processes,extending the industrial chain.
