摘　　要：葫芦岛市位于锦西-哈尔套膨润土成矿带的最南端,为探究葫芦岛膨润土的特性,对葫芦岛的6个膨润土矿进行了研究,通过测定试样的膨胀容、亚甲基蓝吸收量、阳离子交换容量和X射线衍射分析,对葫芦岛膨润土的表观特性、矿物组成、膨胀性能和阳离子交换性等性能进行了评价和表征。研究表明:葫芦岛膨润土矿均为钙基膨润土矿,总体质量较好,大部分膨润土的粒度均匀、自然白度较高,蒙脱石平均含量接近或高于70%。葫芦岛膨润土矿的石英、长石、方解石是主要脉石矿物,矿物组成比较简单,阳离子交换性能较好,在辽西地区膨润土矿中处于中上等地位,具有较强的代表性。然而,辽西膨润土普遍含有方石英,限制了产品的应用范围。Huludao is the starting point of the Jinxi-Hartao metallogenic belt.In order to explore the characteristics of Huludao bentonite,six bentonite mines in Huludao were studied.Crystalline phases,montmorillonite content,swelling property,cation exchange performance of the samples were characterized and evaluated by X-ray diffraction,swelling volume,cation exchange capacity and methylene blue index,respectively.By comparing Huludao bentonite with other bentonites in western Liaoning,the characteristics of bentonite in western Liaoning were summarized.Huludao bentonite belongs to calcium-base bentonite and has the following advantages:high whiteness,high montmorillonite content,simple mineral composition,good cation exchange performance and stable ore quality,which has a strong representativeness in western Liaoning.However,bentonite in the western Liaoning generally contains cristobalite,which limits the application range of the product.
