Chromite lump ore, Chrome ore Briquettes, coke, quartz are mixed in a pre-calculated proportion. The material mix is fed into the furnaces .The ferrochrome alloy is produced via reduction of Chromite ore to an alloy of chrome and iron. The casted alloy from the furnaces is crushed and screened to different sizes according to customer specification.
Chemical-grade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromium-to-iron ratio of 1.5:1 to 2:1. Refractory-grade chromite ores contained a minimum of 20 pct Al2O3 and more than 60 pct Al2O3 plus Cr2O3.
