PRELIMINARY ENRICHMENT OF THE ORE OF THE ZARNISOR DEPOSIT BY THE GRAVITY METHOD IN ORDER TO IMPROVE THE QUALITY OF THE FINAL PRODUCT

The article is devoted to the gravity method of enrichment of the ore from Zarnisor deposit. It considers the efficiency of this method, its main principles and advantages. It also describes the process of ore enrichment using the gravity method and its impact on the final result. The study allows us to conclude that the gravity method is promising in enriching the ore of the Zarnisor deposit and its potential for further development of the mining industry. This article presents the results of a study on the gravity enrichment method, in particular the use of operations - preliminary concentration of ores from the Zarnisor deposit by the enrichment method in heavy suspensions. The obtained results allow us to assume that the removal of quartz and carbonaceous matter from the main size class: -25+10 mm, -7+3 mm, -3+1 mm with tailings (light fractions) will improve the flotation process during enrichment of the heavy fraction and increase the quality of lead and zinc concentrates.
