The increasing costs of electric energy and continuous depletion of quality raw material such as Chromite ore and coke for production of high grade Ferro-chrome imposed a big challenge for the Ferro- alloys industries. In order to sustain in the globalized market, an attempt have been made in the present investigation for production of high grade Ferro-chrome utilizing lean grade raw materials. Chromite ore having different Cr/Fe ratio were smelted in a 100 KVA submerge arc furnace (SAF) with low grade nut coke. The Cr/Fe ratio of the Chromite ore pellets were optimized with respect to the slag basicity and power consumption to yield high grade Ferro-chrome. The basicity of the slag and Cr/Fe ratio of the ore were optimized to produce high grade Ferro-chrome (Cr > 60%) with low power consumption. It was observed that high grade Ferro-chrome can be produced utilizing low grade Chromite ore having Cr/Fe ratio 2.4 at the slag basicity of 1.
