Dry magnetic separation (DMS) enables to separate the non-magnetic fraction of iron ores at the initial stage of their concentration and therefore to decrease cost of their further processing.
Magnetic separation takes advantage of the fact that magnetite is strongly magnetic (ferromagnetic), hematite is weakly magnetic (paramagnetic), and most gangue minerals are not magnetic (diamagnetic). A simple magnetic separation circuit can be seen in Figure 1.2.5 [9]. A slurry passes by a magnetized drum; the magnetic material sticks to …
"Pre-concentration is a necessary step for upgrading low-grade iron ores, and its aim is to remove gangue minerals for improving efficiency of downstream separation process. The most important pre-concentration technique for iron ores, including hematite, siderite and limonite, is magnetic separation based on the …
A processing flowsheet includes magnetic separation, milling and gravity concentration methods. The separation technology provides for production of iron ore concentrate with total iron content of 65.9% and recovers 91.0% of magnetite and 80.5% of hematite from the tailings containing 20.4% of total iron. The proposed technology will increase ...
At the IOTC, ALS has an extensive range of magnetic separators suitable for all batch and most continuous scenarios, as follows: Davis Tubes: The traditional Davis Tube forms the bedrock of every magnetite program in determining the initial weight-recovery response of magnetic iron. This will indicate the proportion of the deposit that is ...
Hematite ore's magnetic characteristics were significantly impacted by magnetizing roasting. By selectively magnetizing roasting, hematite is transformed into magnetite. With an Fe grade of 65.25% at a recovery value of 72.5% in the concentrate, magnetic separation produced the greatest result for Fe.

Concentration of Magnetite Ore . Samples of magnetite ore were ground in a ball mill to minus 100-mesh, deslimed by decantation, and dried. One sample of sand was passed once over the progressing field magnetic separator; a second sample was given like treatment on a disk- type, high -intensity, dry magnetic separator.
The relevance of the paper is that dry magnetic separation (DMS) is the main beneficiation method of magnetite ores. The lack of efficient industrial-grade machines and apparatus for separating fine-grained magnetite ores means that DMS is used mainly as a pre-concentration operation for fairly large classes. The aim of the …
Pre-concentration followed by magnetization roasting and magnetic separation process was well recognized to be very effective in recycling iron from iron ore tailings. An iron concentrate containing 66.35% Fe with a total recovery of 57.74% was produced under the optimal experimental conditions (i.e., roasting temperature, 540°C; …
