Abstract

The present invention relates to the use of hydrophobically associative copolymers as binders for pelletizing metal containing ores such as iron containing ores. The copolymers comprise monomer units derived from at least one hydrophobically as sociative monomer, preferably at least one unsaturated hydrophobically associating monomer.
