Abstract
A process is provided for pelletising a metal ore comprising forming an intimate mixture of particulate ore and a binder in the presence of moisture, forming green pellets by agitation of the mixture and firing the green pellets to produce ore pellets. In the process the binder comprises a hydroxamate polymer made from water-soluble ethylenically unsaturated monomer or monomer blend and which has pendant groups of the formula ##STR1## This provides advantages in wet strength, dry strength and drop number of pellets, especially at low moisture content of the pellets.
