Chromite ores of Muslimbagh area are considered of commercial significance for the synthesis of sodium chromate. As chromite ores of Muslimbagh area are low grade (34% Cr2O3), therefore beneficiation was carried out to obtain required grade (45 - 48%). A good yield of sodium chromate was obtained by roasting and leaching.
