METHOD FOR LOCATION OF MIGRATING METALS IN DUMPS Russian patent published in 1997 - IPC

FIELD: mining industry. SUBSTANCE: this can be used in storing of uranium-containing sub-standard ores and rocks. According to method, successively placed on prepared base are antifiltration and drain courses. Then formed is barrier course (to be beneficiated). Placed on its surface is perforated pipeline, then course to be leached is formed. In period of storing rocks, leaching of uranium takes place under action of weather precipitation or technological solutions artificially delivered from course to be leached, and its migration together with dump water in course to be beneficiated. At mixing of uranium-containing dump water with matters (substances) delivered into wells (pipeline), taking place is technogenic mineral formation with catching of migrating uranium. EFFECT: high efficiency. 3 cl, 1 dwg
