Özet

In this study, beneficiation of the spiral chromite tailings taken from South Africa, which contains 22.5% Cr2O3, were investigated by using combination of gravity units. Shaking table tests were carried out at size fractions such as -0.841+0.355 mm; - 0.355+0.212 mm; -0.212+0.074 mm and Mozley table was used for -0.074 mm, however, appropriate results were not obtained in terms of acceptable concentrate and tailing grade. Therefore, original material was ground under 0.355 mm in size, fractioned and subjected to gravity separation tests. Gravity separation tests were carried out at size fraction between - 0.355+0,150 mm, -0.150+0.074 mm by using shaking table and at -0.074 mm using Mozley table. According to the overall gravity concentration test results under 0.355 mm; 34.6 % of feeding material can be obtained as a chromite concentrate having 41.52% Cr2O3 grade with 62.0% metal recovery. Final tailings having 6.24% Cr2O3 content can be separated with a 7.8% metal losses. Since Cr2O3 concentrate content of 40-42% is found sufficient in line with company's demand, 41.52% of Cr2O3 content is determined as the optimum value.
