ABSTRACT:
The present invention relates to a method for ore pelletization including the step of adding binder polymer to particulate ore and moisture to form an intimate mixture. Green pellets are formed from the mixture and fired. A water soluble treatment polymer having a molecular weight of 1,000 to 20,000 is included in the intimate mixture in an amount of at least 0.001% by weight. The water soluble treatment polymer is formed by polymerization of water soluble ethylenically unsaturated monomer blend containing at least 50% by weight of anionic monomer.
