Metallurgical Grade Chrome Ore Concentrate — Clover Alloys
Chrome ore contains too many impurities to be added directly into a steelmaking furnace. Prior to being consumed in steelmaking chrome ore must be smelted in an electric furnace together with a carbon reductant which eliminates most of the impurities in the ore and produces a product known as ferrochrome. Ferrochrome is an alloy containing 48

Bond Work Indexan overview ScienceDirect Topics
The Bond work index (Bond 1960) is based on Bond s law which states that the energy consumed is proportional to the 1.5 power of particle size rather than the square of Rittinger s law. Accordingly the energy consumed in reducing the particle size from x F to
