Properties and End-Use Functionality of Iron Ore

Unlike iron ore sinter and pellets which are manufactured from iron ore fines and or concentrate, lump can be directly charged to the furnace without any pre-processing. As a result, lump has an inherently higher value compared with fines due to the avoidance of agglomeration costs. Australia is a significant producer of iron ore lump.
