Beneficiation of Konya-BeyAYehir Chromite for Producing Concentrates Suitable for Industry

摘要

Turkey has a 6% share of world chromite mining and possesses 25 million tons of reserves. Despite their economic importance, the most important Turkish chromite reserves have not been extensively studied with respect to their composition. In this study, the possibility of upgrading Konya-BeyAYehir (Turkey) chromite to produce chromite concentrates suitable for industry is investigated. Two groups of enrichment experiments were made. The effects of some parameters that markedly influence the separation of a shaking table, such as the amplitude and slope of the shaking table and the frequency of strokes were investigated in the first group of experiments, The shaking table experiments were planned and carried out using the statistical methods of Design of Experiments (Yate's and ANOVA) in the second group of experiments. As a result, it was found that a concentrate containing 46.89% Cr2O3 content with a yield of 85.18% was obtained from a feed containing 3.98% Cr2O3 content in 0.2 + 0.1 mm size fraction.
