Abstract
A process for pelletizing particles of a fine mineral ore, the process comprises the steps of
- a) mixing the particles of a fine mineral ore with a binder composition to obtain a pellet feed,b) forming the pellet feed into balls,c) drying the balls to form dried balls,d) preheating the dried balls at 60 to 105° C. until constant weight to form preheated balls,e) subsequently heating the preheated balls to a temperature of 1200° C. to 1400° C. to obtain pellets,wherein the binder composition comprises a) at least one colloid agent which exerts a cohesive force on the particles of a fine mineral ore forming the pellets, andb) at least one synthetic polymer which disperses the particles of a fine mineral ore in the pellets,wherein the synthetic polymer is a maleic acid/acrylic acid or a maleic acid/methacrylic acid copolymer.
