Iron Ore Pelletizing Process: An Overview | IntechOpen

Bentonite, an inorganic binder, has been the main binder used in the iron ore pelletizing process since the beginning of pellet production in the 1950s. Bentonite promotes the formation of ceramic bridges between particles, which can minimize the number of pellets that collapse during firing.

(PDF) Iron Ore Pelletizing Process: An Overview

The use of binders for iron ore pelletizing is required to: (a) increase the pellet strength before heating – green strength; (b) prevent the collapse of the pellets during firing, when the ...

Direct reduced iron - Wikipedia

Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)). The direct reduction process is comparatively energy efficient. Steelmade using DRI requires significant…
