REFINEMENT OF STEEL FROM ORE

This paper proposes a novel process for the pre-treatment of high phosphorus iron ore by pre-reduction, air jet milling and screening methods. The dephosphorization behavior was evaluated as a function of such parameters as the milling gas kinetic energy, E k and specific energy consumption, E sp. At a fixed milling gas kinetic energy, the ...
