Abstract
The article discusses hydrochemical modification of properties of zeolite-bearing rocks in East Transbaikalia. It is found that acid-based modification enhances adsorbability of natural zeolites. The technology of processing with chemical modification is developed for zeolite-bearing rocks with regard to the earlier research findings on mineral treatment by ultrasound, accelerated electrons and high-power magnetic impulses. The rate of dealumination and the silicon module of natural zeolites from East Transbaikalia are correlated with the sulfuric acid concentration. The implemented computer-aided modeling of zeolite minerals is based on the quantum-chemical interaction of particles. The authors depict the range of use of the high-quality zeolite products in the technologies of mining waste management.
