The different amounts of magnetite losses are caused by the different particle size of products and the associated size of the surface which the magnetite particles adhere to. What is causing the magnetite adherence to the coal is lack of wash water on that piece of coal. Tab 1.

In coal preparation, the mineral magnetite (FeO, Fe 2 O 3) has become the most commonly used material, not only because it fulfils all the above criteria, but also because of its worldwide occurrence either as an iron ore or as a by-product of mining operations for other minerals. Like any mineral, magnetite rarely occurs in the pure state and ...

Implementation of the above recommendations reduced the magnetite losses in the coal washing plants from about 1.64 kg/t to 1.3 kg/t. This in terms of raw coal processed in the cyclone circuit reduced the magnetite consumption by 639 t, resulting in a savings of US$27,500/annum. The cost savings are shown in Table 5.

It is also used in coal mining operations as a slurry with water to remove the heavier impurities by allowing the less dense coal to float to the surface. The magnetite can be reused in this process 90 percent of the time. Magnetite is also used as a source of iron to manufacture iron-based chemicals and fertilizers.

They use a set of water sprays to wash the coarse coal as it passes across the screening media. A wet-drum magnetic separator is then used to recover the magnetite from the slurry that flows from the drain-and-rinse screens. While magnetite losses are often blamed on the magnetic separator, they could be occurring in another area.
