Abstract: It is always preferred to use uniform high grade ore for production of metallic alloy. But in real life situation, it is not possible to get a homogeneous ore. Chrome ore is one of the precious natural resources having limited availability. The chemical composition of the ore varies horizontally and vertically across the ore body in mines. The ore quality is not uniform in all the faces of the mines. The production requirement being uniform grade of ore, blending of different grades of ore is required at the mines head before using it in the furnaces for smelting. The production requirement is to have a uniform grade metal production to meet the customer specification with minimum or zero deviation.
