An iron concentrate containing 66.35% Fe with a total recovery of 57.74% was …
The Oremax integrates our tried and tested water recycling technology allowing you to use the latest mineral washing technology while reducing your water requirement by up to 95%.
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 …
The function of the flotation area is to recover beneficiation metal into a copper concentrate while rejecting coarse, non-sulfide gangue to first stage tailings and rejecting zinc, lead, and iron sulfides to the tailings stream from the second stage [ 2 ].
The obtained results show that the a high grade iron concentrate (>65% Fe) with lower recoveries was obtained from shaking table tests by using -1 mm fraction. According to the results a flowsheet ...
