iron ore pellet grinding

Iron orepelletisation. BRPL is in operation in producingiron ore pelletsfromiron oreconcentrates after beneficiating low gradeiron orefines. The low grade fines with Fe less than 56-57% are beneficiated at beneficiation plant throughgrinding, gravity & magnetic separation process to produce high gradeiron oreconcentrates with 63-64% Fe.
