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.

Innovative Development on Agglomeration of Iron Ore

2020-4-23  Apart from these, there are lean grade ores which are not used directly in the blast furnace or DRI making. These ores are generally crushed and ground to powdery size and are upgraded through several beneficiation processes. The bene-ficiated products are available in form of fines which require agglomeration before using in iron making furnaces.
