Recovery of Iron Values from Iron Ore Slimes of . 2015-12-21 The beneficiation of iron ore slimes produced from washing plants and tailing ponds of Kiruburu mines was studied using wet high-intensity magnetic separators (WHIMS) followed by classification in hydro-cyclone whereby a concentrate assaying 63 % Fe and 3.3 % alumina was produced with an overall iron recovery of 56 %.

Recovery of values from tailing ponds of iron ore washing

Most of the Iron ore washing plants set up in India in the earlier days consist of sizing of the ore by dry / wet screening, washing and classification by screw classifiers. In this classical approach, iron values were lost in the form of fines and utrafines into the tailing ponds as they had little commercial value in those days and accumulated in huge quantities over the years.

The iron ore deposits in India are rich in iron content but usually contains high alumina and silica. The current industrial practice results three products namely lump, fines and slimes. The lump and fines with or without beneficiation are directly fed to the blast furnace and sintering plant respectively while the super fines or slimes are presently discarded as tailings.

Tailings Paste Disposal More than Water Recovery

2021-9-7  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.
