In the pelletizing industry the produced green pellets are then dried, sintered, cooled and lastly sent to the steel production industry. The pelletizing of iron oxide fines is a solution to the dust formation problem caused by fines which are fed to steel production blast furnaces.
Bentonite is the common name for naturally occurring clay that contains the active montmorillonite mineral. The special properties of montmorillonite that enable commercial applications include the submicron platelet structure, very high surface area ( ≈ 800 m 2 /g), and inherent negative charge in the platelet that is counter balanced by exchangeable cations.
