Abstract
Acoustic and thermal treatment of zeolite rocks of East Transbaikalia is discussed. The mineralogy and chemistry of the largest natural zeolite deposits in Transbaikalia are described. It is found that quality of zeolite can be affected by iron impurities, montmorillonite, hydromica, quartz, calcite, potash feldspar, crystobalite and pyroxene. The experimental data on efficiency of directional effects on zeolite rocks are presented. The zeolite rock processing technology is developed with regard to the previous research results on effects of accelerated electrons and high-power electromagnetic pulses. Modification of properties of minerals in composition of zeolite rocks is assessed. It is found that magnetic properties of iron-bearing impurities in zeolite change, which improves efficiency of removal of these impurities. The capability of the suggested methods to enhance adsorption capacity of East Transbaikalia natural zeolites within the processing flow charts is illustrated.
