Abstract | Cryptocrystalline zeolitic rocks fractionation and concentration processes are studied, using separation in organic liquid of varying density, concentrating table and flotation. A possibility to obtain products with varying content of zeolite, opal-christobalite-tridymite phase and calcite-quartz association has been established. It is shown, that opal-christobalite-tridymite phase is a most suitable product for manufacture of cellular constructional materials like foamglass. Raw material mechanical activation possibilities are studied as a pore formation intensification method. In addition to increase in dispersion and reactive capability of zeolitic rocks components in mechanical processing under the conditions of centrifugal planetary mill, liberation of intergrowths in cryptocrystalline formations has been established, having a favorable effect on pore formation process in production of materials with improved thermal-insulating properties. |
