Abstract

See full text

The present invention discloses a method for arranging in piles, instead of in dams, the tailings generated by iron ore processing, said method comprising the steps of thickening the ultrafine tailings, thickening the sandy tailings, mixing the tailings at a ratio of 80-90% sandy tailings to 10-20% ultrafine tailings by weight, adding coagulant, adding flocculent, filtering the mixture and piling the filtered tailings. Unlike the traditional methods, the present invention provides an economically and technically viable method for arranging tailings in piles, which can be used in any conventional iron ore concentration plant without having to alter the process flows in any way.
