  • Recovery Of Iron Ore Tailings Bycolumn Flotation

    the exploration of iron ore in small mining companies results in a large amount of unrecovered fine material, representing 35% of the run of mine. millions of tons of useful minerals are discarded every year into tailings, incurring operation costs, raising production losses and environmental impact. In addition to the disposal of 300 th of this material, millions of tons are already stored the level of impurities, loi and fine material has a significant impact on sinter quality and sintering performance. hence, understanding the technologies used throughout the iron ore supply chain is of increasing importance in tailoring products to better suit the needs of end users.
