The feasibility of producing Direct Reduced Iron from coldbonded selfreducing composite pellets made from Anglo American Kumba Iron Ore Sishen upgraded slimes was considered on laboratory scale. Composite pellets were made by mixing Sishen upgraded slimes, coke and different binders using a pelletizing disc by addition of moisture.

Iron Ore pellets are superior to other substitutes owing to its High Cold Crushing Strength resulting in minimal fines generation while multiple handling and resulting in increased savings. With uniform composition of material, size and Guaranteed Porosity, Swelling Index and negligible moisture due to dry process provides an added advantage for Smooth Operation in Kiln / Furnace and improves productivity.

Crushing Strength Testing Machine for Iron Ore Pellets (AIM 675) Ref. Standard IS04700,ASTM E 382 . Crushing Strength is the maximum compressive load at which an iron ore pellet is broken completely. Compressive load is applied on the pellet between two parallel platens at a uniform speed of 15 ± 5mm/min over the entire period.

For this reason, a high metallic iron content of pellets, greater than 70 %, is generally required in order for reduced pellets to attain the strength required for use in blast furnaces. Gupta and Gautam [ 31 ] reasoned that the strength of DRI could be increased by enhanced metallic or slag bonding within the pellet.
