A binder for pelletizing particulate mineral material. The binder including about 50-99.5% modified native starch, and about 0.5-50% of water-dispersible polymer material selected from the group consisting of water-dispersible nature gums, water-dispersible pectins, water-dispersible starch derivati

A binder for pelletizing particulate mineral material. The binder including about 50-99.5% modified native starch, and about 0.5-50% of water-dispersible polymer material selected from the group consisting of water-dispersible nature gums, water-dispersible pectins, water-dispersible starch derivatives, water-dispersible cellulose derivatives, water-dispersible vinyl polymers, water-dispersible acrylic polymers and mixtures thereof. An iron ore concentrate is also disclosed as are mineral ore and iron ore pellets. In addition, methods of binding particulate mineral material and of making mineral ore pellets are also disclosed.
