India has limited resources of chromite. To optimally exploit this valuable and strategic raw material, numerous chrome ore beneficiation plants have been established. 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 …
DOI: 10.5277/ppmp19006. shaking tables to sort material in narrow size/density fractions in order to improve the metallurgy (Burt 1984). Besides conventional systems, a new gravity concentration equipment, the vibrating table, has recently been developed and tested for chromite ores (Gülsoy and Gülcan, 2019).
Abstract and Figures. In this study, an optimum beneficiation route was developed for an existing concentrator that processes low-grade chromite deposits. This objective is challenging as the ...
Typically, chromite ore processing is performed using gravity separation techniques (including shaking table, spiral) due to the significant difference between the specific gravity of the valuable mineral and the associated gangue minerals. ...

During the beneficiation of chromite ore of Sukinda region, approximately 50% (by weight) of the total feed is discarded as tailing which contains a significant amount of chromite. Several studies have focused on reduction of chromite losses in the beneficiation plant tailing (Rao et al., 1987, Raghukumar et al., 2009, Tripathy et al., 2011).
The critical area of concern in any chrome ore beneficiation plant is the grinding circuit followed by beneficiation circuit comprising gravity units such as wet shaking tables and spirals. The effectiveness of grinding circuit depends on the …
