The second pair were strongly magnetized and attracted the wolframite, which is weakly magnetic. These machines were capable of treating 10 tons of ore a day. Common applications. Magnetic separation can also ...

Dry Iron Ore Beneficiation | Iron Ore Separation - ST ...

Magnetic separation is typically used in the beneficiation of high grade iron ores where the dominant iron minerals are ferro and paramagnetic. Wet and dry low-intensity magnetic separation (LIMS) techniques are used to process ores with strong magnetic properties such as magnetite while wet high-intensity magnetic separation is used to separate the Fe-bearing minerals with weak magnetic ...

Assessing the performance of a novel pneumatic magnetic ...

01.09.2020· Dwari et al. (2013) used a combination of dry and wet magnetic separation methods to upgrade a low-grade siliceous iron ore with magnetite, hematite, and goethite as major iron minerals. The study showed that for particles finer than 200 µm, the separation methods produced a magnetic concentrate with 67% iron and iron recovery of 90%. Also, investigations into the use of dry high …
