Mining Production Iron Steel From Hematite And Magnetite

For years magnetite ore was considered inferior to hematite the main source of iron ore this was because hematite contains much higher percentages of iron between 56 and 64 whilst magnetite only contains between 25 and 40 magnetite must be concentrated before it can be used adding cost and time to the process.
