“…The ferruginous chromite ore deposits are mostly found in India. The achievable Cr:Fe ratio of the concentrates varies from 1.5 to 2.8 from a low-grade deposit with Cr:Fe ratios of 0.5 to 1.0 by using gravity separation [4,[10][11][12][13].…”

The low chromium‐to‐iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium‐to‐iron ratio. Also, detailed characterization studies including automated mineralogy were carried out to better understand the nature of the samples. Enhancing the chromium‐to‐iron ratio was achieved by using advanced spiral separators which will be discussed in this paper.

“…The redistribution of Cr 2 O 3 to gangue minerals can lower the efficiency of the physical separation plants [3]. Different beneficiation techniques such as gravity separation [4][5][6][7], flotation [8][9][10][11][12] or magnetic separation [13][14][15][16][17] can be applied to remove gangue minerals from the chromite concentrates.…”

Abstract:The present work is undertaken to determine the effect of operational variables, namely: feed rate, centrifugal force and fluidization water flow rate on the efficiency of Knelson concentrator for chromite ore beneficiation. A full factorial design with three factors at three levels and response surface methodology (RSM) were applied for this purpose. The quadratic models were developed to predict the concentrate Cr 2 O 3 grade and recovery as the process responses. The results suggest that all the variables affect the grade and recovery of the Cr 2 O 3 concentrate to some degree. However, the fluidization water rate was found as the most effective parameter.
