Considering the tailing disposal problems of chromite gravity plants, the research works carried out by Amer and Ibrahim (1996) on hydrometallurgical processing of low grade chromite ore (Barramiya, Egypt), with a new technique using mechanical alkaline treatment in an attritor followed by oxidative leaching in an autoclave reveals that even a ...
Shaking tables are more popular due to high separating accuracy. Among the chrome beneficiation machines, jigs are for chromite rocks with medium and fine grain sizes, and shaking tables are for fine chromite ore. The combination of jigs and shaking tables is more prevalent in the chromite gravity separation plants for the best recovery …
2.1 Materials. Tata Steel Ltd., has its Chromite Ore Beneficiation (COB) plant at Sukinda zone, Jajpur district of Odisha state, India. It was observed that during beneficiation, substantial quantity of chromite tailings was produced and these tailings were stocked in the dam [2, 3].For research work, tailing sample was collected from …
The chrome ore washing plant mainly includes washing and gravity separation processes to extract high-quality concentrates. Magnetic separation technology is needed to remove impurities if the ore contains iron minerals. First, it must be washed, and the ore is separated from the mud by hydraulic flushing or additional mechanical scrubbing.
The tailing sample was beneficiated by hydrocyclone, tabling, wet high-intensity magnetic separation (WHIMS), and flotation in order to recover the chromite. A chromite concentrate with 45.29wt% Cr2O3 and a Cr:Fe mass ratio of 1.85 can be produced from these low-grade chromite ore beneficiation plant rejects.
Abstract and Figures. This study aimed to evaluate the chromite recovery from shaking table tail-ings of Forumad plant by a dry high-intensity magnetic separation. The average feed grade of ...
Most of these plants suffer chromite losses into the tailing. Decreasing these losses would not only improve the plant performance but also make the economics of the operations more attractive. Accurate data collection and interpretation, followed by making an implementable change in an operating plant, plays a critical role in the performance ...
The aim of this study was to optimize the recovery of chromite from the chrome plant tailings of the South African Middle Group chromite seams using a shaking table.
