Magnetite is a form of iron oxide, Fe 3 O 4, which possesses uniquely iron in both the Fe 2+ and Fe 3+ oxidation states. Bearing the form of an inverse spinel, it''s magnetic properties are highly valued. Addition of magnetite to soil is advantageous as it can later be removed easily by using magnets. It can occur naturally in soil, or be added as a soil treatment agent.

In this work, we selected magnetite as the magnetic particle and propose the hydrothermal synthesis of MOR zeolite/magnetite composite via seed assisted method for the first time. MOR zeolite/magnetite composite with high MOR zeolite crystallinity was obtained by synthesizing for only 6 hours at 463 K when adding seed crystals, while no sign of crystallization was observed even after 24 hours ...

Export magnetite is used for iron and steel production. After removing magnetite, underground ore tailings flows to three parallel 90 meterdiameter tailings thickeners to recover water and reuse, while the combined underflows are pumped to various points around the perimeter of a large tailings dam.

The resulting magnetite concentrate contains unliberated magnetite (magnetite particles that are still attached to other minerals) which requires further milling so that the magnetite can be liberated and extracted. Unliberated magnetite is usually larger than liberated magnetite, so the two can be separated according to particle size.

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavyduty gang milling operations.
