What is the size of iron ore which feeded in a blast furnace?

Historically the sizes of iron ore sent to the blast furnace have been varying as the advantage of close sizing was gradually realized. Till 1950s the size (from manual mining and hand picking) was 12.5 mm (1/2″) to 200 mm (8″) and the ore below half inch (not more than 10% to 15% of the total mining product was mostly rejected.
