to ore, which remains in tailings after the extraction process. Due to the above reason tailings are hazardous in nature. Leaching of heavy metals is another concern associated with tailings. Due to this the disposal of mine tailing is a serious environmental issue for any mining projects. In order to
Tailings, also called mine dumps, culm dumps, slimes, tails, refuse, leach residue or slickens, terra-cone (terrikon), are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore.
The concentration of iron ore by flotation is a technique consolidated worldwide for mineral particles ranging from 10 to 250 μm . In Brazil, all the main pellet-feed producers use re- verse flotation, being the tailing made up mostly of quartz and a concentrate constituted of iron oxides and iron hy- droxides.
