high recovery ratio experimental magnetic separator for iron

Oolitic iron ore is one of the most important iron resources. This paper reports the recovery of iron from high phosphorus oolitic iron ore using coal-based reduction and magnetic separation. The influences of reduction temperature, reduction time, C/O mole ratio, and CaO content on the metallization degree and iron recovery were investigated in detail. Experimental results show that reduced

    Drum separators are affected by the amount of magnetics in the slurry. The recovery decreases in dilute slurries — an effect not seen in high gradient separators. Also they are limited to 20% solids or less in the feed and 60-70 gpm/ft of drum width if the non-magnetics content is re- quired to be less than 10%

    Effect of magnetic intensity on separation of vanadium, titanium and iron. In this study, magnetic separation was used to obtain high-quality vanadium concentrates from the VTM ore. The production of titanium-rich concentrates to recover titanium was also very important because the VTM ore contains high ilmenite [26,27]. Therefore, from the

    The iron recovery was determined by mean of the ratio of iron concentration after and before magnetic separation. Experimental results showed that increasing magnetic field strength and decreasing coal fly ash grain size in a wet separation will increase the recovery of magnetic iron component.
