Sodium hydroxide and starch were used to regulate the slurry pH and to depress iron ore, respectively. Various iron ore sam-ples drawn from different mines and their mixtures were sub-jected to the test work. Results of pilot scale tests clearly indi-cate the superiority of flotation column vis-a-vis conventional cells and dual extraction column.
