2023年1月1日 The chrome ore beneficiation circuit, Sukinda is shown in Fig. 3.3. The plant is designed to produce concentrate of three different size ranges, that is, coarse (−1 mm + 106 µm), fine (−106 µm + 70 µm), and ultrafine (−70 µm + 25 µm). The beneficiation circuit comprises of a combination of hydrocyclone, floatex density separator
Knowledge of the chromium ore minerals proper and their associated rocks-forming minerals is needed to explore new chromite fields and to predict the efficiency of individual methods for the beneficiation of chromite ores.
In India, at both the Sukinda and Boula-Nausahi sectors, chrome ore is mined by opencast mechanized mining methods, though a few underground mines exist which are confined to Byrapur in Karnataka and the Boula and Kathpal mines in Odisha. The overall beneficiation scenario is outlined in Figure 4. Performance of gravity concentrators
