摘要：

By combining the low specific gravity and fine particle-size characteristics of clinoptilolite in soils, it is possible to separate the zeolite from complex mineral systems. Clinoptilolite has a specific gravity of about 2. 16, and most of the clinoptilolite in soils derived on the Catahoula sediments are concentrated in the 50-2- mu m fraction. The objectives of this study therefore were to: (1) separate clinoptilolite from soils, and (2) test for possible mineral alterations caused by the separation procedure. Study materials, methods and results are discussed.
