众所周知,膨润土这种以蒙脱石为主要矿物组份的粘土矿产,由于具有吸水膨胀性、分散悬浮性、粘滞性、触变性、润滑性、可塑性和粘结性,及具较强的阳离子交换等独特性能,广泛地被应用在工农业生产上,成为国民经济建设中不可缺少的矿产资源。根据膨润土交换的阳离子种类及相对含量,可分为钙质膨润土、钠质膨润土、镁质膨润土和氢质膨润土等,而以钠质膨润土质量最佳、用途最广。就目前国内外典型的钠质膨润土矿床来看,钠质膨润土有着自身的成矿条件,更由于膨润土具备较强的阳离子交换性能,在自然界水介质的长期作用下发生演变,其变化
It is well-known that bentonite, a clay mineral mainly composed of montmorillonite, has the advantages of water absorption, dispersibility, viscosity, thixotropy, lubricity, plasticity and cohesion as well as strong cation Exchange and other unique properties, widely used in industrial and agricultural production, become an indispensable mineral resources in national economic construction. According to the type and relative content of bentonite exchanged cation, it can be divided into calcium bentonite, sodium bentonite, magnesia bentonite and hydrogen bentonite, etc. However, sodium bentonite has the best quality and widest use. At present, the typical sodium bentonite deposits at home and abroad point of view, sodium bentonite has its own metallogenic conditions, but also because of bentonite has a strong cation exchange performance, the long-term role in the evolution of the natural aqueous medium, the changes
