The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional beneficiation techniques used to achieve a suitable ...


It can be seen from Fig. 11a and b that coarse zircon recovery occurs exclusively in the Knelson Concentrator while the Falcon Concentrator recovers fine-grained light REM (Fig. 11c and d). Recovery of coarse iron oxides occurs in the Knelson, while fine grained iron oxide in the Falcon shows higher recovery ( Fig. 11 e and f).

The Knelson Concentrator takes advantage of the difference in specific gravity between gold and gangue minerals to realize a separation. The centrifugal force magnifies the difference in specific gravity and the rotor geometry facilitates retention of gold particles in preference to low SG particles that are rejected with the process rotor.


The combination of a Knelson Concentrator with low intensity wet drum magnetic separation was found to efficiently concentrate REM while also rejecting high specific gravity iron oxide minerals. A novel finding from this study is the concentration of heavy REE …
