Increasing efficiency of equipment work for preliminary separation of non-ferrous metals

Abstract

<jats:p>The article provides an overview of the methods for pre-sorting sulfide ores, as well as the design of separators for implementing these methods. The practical prospects of the use of radioresonance and X-ray fluorescence separation for the preliminary preparation of sulfide ores are shown. The use of not one, but two or more different physical properties of the separated ore components during radiometric beneficiation opens up additional possibilities in increasing the selectivity of this process and expanding the scope of its application. It is proposed to reduce the energy intensity of crushing processes, due to the impact on the rock electrical breakdown of ore in order to reduce its strength. In this case, the processes of crushing and grinding are replaced by processes of selective destruction along the boundaries of inclusions of the useful component. The substantiation of the technology for the separation of poor copper-zinc ores is presented. The relationship of sulfide content and electrical breakdown voltage is shown.The results of experiments in determination the specific energy consumption for the electrical processing of lean ore, depending on the sulfide content, are presented. The principle is substantiated, and a simulation model of the separation process is developed. The block diagram of the separation process algorithm is given.A description of the methodology for working with software is done. The energy costs of a new technology for the separation of poor sulfide ores are determined.</jats:p>
