Abstract

To obtain a chromite concentrate with an acceptable silica content, it is very promising to apply the method of hydrochemical enrichment, which will make it possible to develop waste-free technology for leaching chromite ores and reduce the silica content in chromite concentrates. Before hydrochemical processing, it is advisable to apply the technology of gravity concentration. Modern gravity enrichment technologies make it possible to efficiently produce chromium concentrates from large and medium fractions of chrome ores, while fine sludge is practically not enriched due to the difficulty of separating complex minerals into concentrates and waste rock. This paper presents the results of processing of tailings processing. The technology involves the enrichment of the fine fraction of tailings of the concentrating plant of chrome ores by gravity methods using a KNELSON centrifugal separator. In technology, the efficiency of the operation of gravity enrichment is provided by the preliminary activation of the fine fraction in sodium bicarbonate solution.
