摘 要:近年来甘肃山丹、白银等地中生代和晚古生代地层中相继发现较大型天然沸石矿床、沸石种类为高硅型斜发沸石,品位较低,为天然沸石贫矿,经作者研究,该沸石贫矿除在建材、饲料及农田改良中作一般性应用外。其经选矿,可作为合成石油化工上广泛应用的催化剂的优质天然原料。具有巨大的开发前景和经济效益。Recently the bigger natural zeolite ores are one after another discovered in late Palaeo-zoic and Mesozoic strata of Shandan county and Baiyin city in Gansu province。The type ofzeolite is high silicon clinoptilolite,These ores belong to natural poor zeolite ore becausetheir grade is lower。According to study of authors,the ore may be not only immediatly ap-plied to building materials,feed and improving farmland,but also it is good nature materialsof catalyst which is widely used in synthetic petrochemical industry after ore dressing。Theore has great applied future and enconomic value,
