Recovering Iron from Iron Ore Tailings and Preparing

Iron ore tailings (IOTs) are a form of solid waste produced during the beneficiation process of iron ore concentrate. In this paper, iron recovery from IOTs was studied at different points during a process involving pre-concentration followed by direct reduction and magnetic separation. Then, slag-tailing concrete composite admixtures were prepared from high-silica residues.

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 t/h of this material, millions of tons are already stored

Maximizing the recovery of fine iron ore using magnetic separation Most iron ore operations that require beneficiation of ROM ore to produce lump, fine (sinter), and pelletizing concentrate iron ore products will discard a slimes fraction to final tailings. This fraction can vary in particle size from –200 µm down to –10 µm.

Tailings Paste Disposal More than Water Recovery

For example, a tailings stream in an iron ore application could be thickened to 45-50% solids in conventional or high-rate thickeners. Conversely, the same tailings stream could be thickened to 65-70% solids using a paste thickener. This increased water recovery is important to many countries throughout the world due to the scarcity of fresh water.
