magnetic separation method - bekemolen

· In fact, magnetic separation is the only feasible method for recovery of small magnetic particles (diameter ca 0.1 – 1 μm) in the presence of biological debris and other fouling material of similar size. Moreover, the power and efficiency of magnetic separation procedures is especially useful at large-scale operations.

This extremely strong magnetic field enables industrial minerals such as limestone or kaolin to be upgraded further. For the smaller grain sizes of up to 5 mm, the higher degree of breakdown results in higher qualities. Salts can also be upgraded or cleaned by this method, by the separation of clay-containing contaminants.

Thermal drying of the wollastonite ore is carried out to ensure effective magnetic separation. Alternatively, initial grinding is followed by wet wollastonite processing (flotation) to remove minerals such as calcite, diopside, and feldspars. Filtration and thermal drying of the resulting wollastonite concentrate is required after wet processing.
