Production of High Carbon Ferrochrome by Smelting Reduction

The advantage of agglomerating the fine chrome ore consists in the fact that the fine ore can be smelted industrially. But it must not be overlooked that the agglomeration of the fine chrome ore causes considerable expense and also only allows the smelting of ferrochrome alloys containing 6.5 to 8% by weight of carbon.
