Abstract
The contribution is focused on the relation between sorptive efficiency, mineral structure, and reclamation extraction of clay sorbents originating from the Most Basin. Clay sorbents are an important accessory raw material that occurs on several localities in the North Bohemian Brown Coal Basin, which are briefly described in the first part of the paper. The results from clay sorbents were obtained by mineralogy survey based on a diffract analysis with a D 5000 Siemens X-ray diffractometer. Localities, where zeolites and montmorillonites were found, are the main subjects of the research. The results show that parameters of clay sorbents mined in these localities are suitable for reclamation works. A successful reclamation with the use of bentonites is demonstrated on Strimice dump.

Summary
The Most Basin (formerly North Bohemian Brown Coal Basin) represents the largest supply of brown coal in the Czech Republic. The surface brown coal quarries caused considerable damage to the surrounding landscape. Rapid adaptation and step by step incorporation of these anthropogenic formations into territory’s ecosystem is in the interest of both the region’s inhabitants and the mining companies. Successful reclamation works require fertilization of sterile and phyto-toxic sites. Natural clayey sorbents are possible solution in this case. Clays are often used in agricultural applications, in engineering and construction applications, in environmental remediations, in geology and in many other
