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.

Process for scavenging iron from tailings produced by

We claim: 1. A process for recovery of iron from iron ore consisting essentially of subjecting the ore to cationic gangue flotation to produce a flotation concentrate as underflow and flotation tailings as overflow, and subsequently scavenging iron from said tailings by means of a wet high-intensity magnetic separator, whereby a magnetic concentrate of increased iron content and a magnetic

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.
