  • Advances in Alternative Binders for Iron Ore Pellets ...

    The replacement of bentonite as the standard iron ore binder is an important factor in the future of iron processing. Bentonite adds unwanted silica to the final concentrated iron ore product. Excess silica from bentonite addition has been calculated to consume approximately 2.4 MJ of additional energy during the production of one metric ton of pig iron.

  • Pelletization - an overview | ScienceDirect Topics

    The ore is crushed, ground, and concentrated in several steps to very small grain size—e.g., over 75% less than 45 μm. Binder (bentonite or organic) and possible additives are fed in the slurry and mixed before filtering. The filter cake is transported to large balling drums or balling discs to be rolled to green pellets.

  • Alcotac – synergistic organic binders

    Binders are used to make the moist ore plastic so that seeds are nucleated and pellets grow at a controlled rate. The binder holds the green pellet together until strong bonds are formed in the induration process where the agglomerates sinter together at temperatures of around 1300°C. Bentonite was the first binder used and is still employed today
