The present invention discloses a process of disposal of tailings in piles stemming from the iron ore processing method, replacing dams, and comprising the steps of thickening the ultra-fine tailings, thickening the sandy tailings, mixing the tailings in the proportion of 80 to 90% by weight of sandy tailings and 10 to 20% by weight of ultra-fine tailings, addition of coagulant, addition of flocculant, filtering the mixture and piling the filtered tailings.
