Particulate ore is pelletised by forming an intimate mixture with particulate binder in the presence of moisture, forming green pellets by agitation of the mixture and then firing these to produce ore pellets and the particulate binder comprises particles of a water soluble, partly cross-linked, polymer formed from water soluble, ionic, ethylenically unsaturated monomer or monomer blend, wherein the extent of cross-linking is insufficient to render the particles predominantly water insoluble but is sufficient to increase the dry strength of the ore pellets.
