  • Iron ore pricing explained

     · In general, higher purity ores help increase hot metal yields in the blast furnace, and also lower production cost by reducing the amount of coke required. For these reasons, the rule of thumb is "higher Fe grade, higher price.". Iron ore also differs in physical form. Fines require sintering (agglomeration into crude pellets) prior to use ...
