察尔汗盐湖是一个现代内陆盐湖钾矿床,富含钾的晶间卤水是该矿床主要开发利用对象。在比较均一的石盐层中,卤水化学组分垂直分带明显,在国内外盐湖中较为少见(表1)。原来平均含钾量中常的晶间卤水,由于垂直分异,钾富集在卤水层上部,利 Chalhan Salt Lake is a modern inland salt lake potassium deposit, potassium-rich intercrystalline brine is the main development and utilization of the deposit object. In the relatively homogeneous rock salt layer, the vertical zonation of brine chemical components is obvious, which is rare in the salt lakes at home and abroad (Table 1). The original average potassium content of the intergranular brine, due to vertical differentiation, potassium enrichment in the brine above, Lee
