1/. Waste water purification by the "Magnafloc" and similar systems. Search "Magnafloc".
2/. Used in coal washing/preparation plants as a heavy medium. Suspension of magnetite in water has a high specific gravity. Relatively clean coal floats on the suspension, stony coal and dirt sink. Search "Drewboy bath" . Also used in cyclone separators in such plants.
Magnetite is removed from the waste process water with a magnetic separator and recycled in both processes.
