Improving the quality of zeolite-containing rocks of the Eastern Transbaikal region on the basis of the application of directed energy impacts

The issues of application of directed energy impact by accelerated electrons on zeolite-containing rocks of Eastern Transbaikalia, represented by the Shivyrtuyskoye and Talan-Gozagorskoye deposits, are considered in order to increase the efficiency of separating zeolites from rock-forming minerals by the method of electromagnetic separation. Results have been obtained to determine the efficiency of opening zeolite minerals using the impact of an accelerated electron flow, dependences have been established that characterize the effect of radiation exposure by an accelerated electron beam on the granulometric composition of zeolite-containing rocks, clinoptilolite and chabazite minerals in them and on the coefficient of opening of zeolite minerals during grinding without radiation treatment and with such. The dependences of the extraction of iron minerals from zeolite-containing rocks of Eastern Transbaikalia on the strength of the magnetic field of the separator for various size classes have been revealed. The dependences of the extraction of iron minerals by electromagnetic separation on the size of zeolite-containing rocks under radiation exposure and the content of iron minerals on the size of zeolite-containing rocks subjected to radiation treatment after electromagnetic separation are determined. The results of electromagnetic separation of zeolite-containing rocks, as well as the results of electromagnetic separation of finely dispersed zeolite-containing rocks in an isodynamic field are obtained. The effect of treatment with accelerated electrons on the sorption capacity of zeolite-containing rocks has been established. A technological scheme for the processing of zeolite-containing rocks has been developed, based on the use of accelerated electron processing at the stage of ore preparation, which provides a significant increase in the quality of zeolite products.
