Fly Ash by a Novel Dry Separation Method [27] implemented a combination of four devices: an electro-mass-classifier, a magnetic separator, a triboadhesion separator and an electrostatic separator. As a result, they achieved four fly ash fractions; among these was a coarse by-product with a MS content of around 2–4 wt.% and MS recovery of .

The dry magnetic separation for magnetite concentrate obtained was studied first. In the tests, two magnetic intensities (MI) were used: low-level (0.13 T) and high-level (0.26 T). As shown in Figure 3, then low-level MI was used, the major part of the raw CFA concentrates into the non-magnetic fraction (I).

Coal fly ash was first mixed with water at a liquid-to-solid ratio of 4:1 (mL/g) and then placed into a wet magnetic separator. Magnetic flux densities of 4300 G and 10 800 G were applied. The magnetic component stuck to the induced magnetic balls when the fly ash solution flowed around the balls in the magnetic separator.
