    Abstract: In the present work, Dextrin is used as a binder for iron ore pelletization, as it's free from Silica and Alumina. Green pellets were prepared by mixing of iron ore particles ( 75 µm) with varying binder percentage (1 wt. % bentonite, and 1 wt. % of dextrin) separately. The green pellets were first dried in air for 24 h and then in an electric oven at 383 K for 4 h. The dried ...

     · The organic binders and inorganic materials tested as binders in iron ore pelletization have been reviewed by Sivrikaya (2011). The aim of this study is to propose the addition of a slag bonding/strength increasing constituent into pellet feed to provide pellet strength with the use of organic binders. Addition of boron compounds into pellet might be a potential solution to improve the lower ...

    Highlights Organic binders and colemanite were tested as alternative binder to bentonite. Colemanite was more effective than bentonite to get sufficient strength. Firing temperature can be lowered with addition of colemanite. Low firing temperatures will be beneficial to save energy in pelletization plants. Bonding mechanism was physical melting at the contact points of iron ore grains.
