Zusammenfassung:	This invention relates to a binder composition for the manufacture of iron ore pellets containing: a) at least two organic binding agents LO in the form of solid particles, which are at least: - a water-soluble anionic polymer PI with a weight average molecular weight between 500 and 200,000 daltons, and, - a water-soluble anionic polymer P2 with a weight average molecular weight greater than 500,000 daltons; and; b) at least one inorganic binding agent LI in the form of solid particles, the solid particles of the binding agents LO having a number median size of more than 500 micrometers, the particles of the binding agent LI have a number median size of less than one-third of the number median size of the solid particles of the binding agents LO.
