Abstract

A binder for pelletizing particulate mineral material. The binder including about 30-99.5 % modified native starch, and about 0.2:80 % of water-dispersible polymer material selected from the group consisting of water-dispersible natural gums, water-dispersible pectins, water-dispersible starch derivatives, water-dispersible cellulose derivatives; water-dispersible vinyl polymers, water-dispersible acrylic polymers and mixtures thereof: Alternate embodiments include from about 0.5-50 % lignosulfonates and/or about 0.2-40 % soda ash. Mineral 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.
