Use of hydrophobically associating copolymers as binders for pelletizing metal containing ores

The present invention relates to the use of hydrophobically associative copolymers as binders for pelletizing metal containing ores such as iron containing ores. In many cases, Bentonite, an absorbent aluminium phyllosilicate, is used as a binder since its use typically provides pellets with the required mechanic properties, e.g. wet strength, dry strength and drop number. Bentonite swells up on contact with water and forms a viscous sticky mass that is used as the active binder. However, the Bentonite is not burned off during the firing process and thus, residual Bentonite or other silicon-based derivatives thereof formed during sintering remain, which is undesirable. Overall, there is still a need to reduce the amount of Bentonite in metal-containing ore pellets while at least maintaining desired mechanic properties of the metal containing pellet. There is also still a need to provide other organic binders for the pelletizing of metal containing ores to afford metal containing ore pellets with desirable mechanic properties. It is thus an object of the present invention to produce metal-containing ore pellets that provide desired mechanic properties by using organic binders. The copolymers comprise monomer units derived from at least one hydrophobically associative monomer, preferably at least one unsaturated hydrophobically associating monomer.
