The presence of the usually unwanted, hydrophilic ore particles (gangue) in a mineral flotation froth plays a critical role. While they reduce the grade of the concentrate, they are also an important influence on the dynamical structure of the froth and its ability to transport value particles into the launder for ultimate recovery.

An iron ore pelletizing plant produces typically between 4 and 7 million tonnes of iron ore pellets per year, which corresponds to an hourly production rate of 500 to 900 t/h. Agglomeration is started by grinding and upgrading the iron ore to a concentrate with desired chemical quality and with a particle size distribution suitable for balling.

The collector is the most important reagent used in the iron ore flotation process. The function of the collector reagent is to promote affinity between mineral particles and air bubbles by formation of a water-repellent coating on the surface of the mineral particle. Most collectors in current use are heteropolar; i.e., they contain both a polar
