Coal Cleaning
Coal Cleaning. Coal cleaning is an option for removing mercury from the coal prior to utilization. Of the more than 1 billion short tons of coal mined each year in the United States, about 600 to 650 million short tons are processed to some degree [91 ]. Coal cleaning removes pyritic sulfur and ash. Mercury tends to have a strong inorganic ...

Magnetite and Magnetite Mining in Canada
Magnetite (also magnet iron, magnet iron stone, iron oxide, or iron (II, III) oxide) is the most stable iron oxide with high resistance to acids and alkalis. It has a cubic crystal system and a chemical molecular formula Fe3O4. One of the iron ions is divalent. The other two are trivalent, so Magnetite is also referred to as iron (II, III ...

An analysis of medium losses in coal washing plants
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.

The application of magnetite for coal preparation in …
Finely ground magnetite, a dense form of iron oxide, is used in the preparation of the heavy medium suspensions used in the separation units. The average magnetite loss from a large heavy medium coal-cleaning facility can be as large as 10,000 to 13,000 tons per year, representing nearly one million dollars of annual operating costs.

Regular Inspections Prevent Magnetite Losses
The only thing worse than losing magnetite is losing clean coal. Both are unnecessary expenses that can be prevented with regular inspection and maintenance. Drain-and-rinse screens play a pivotal role in magnetite recovery in heavy-media prep plants. They use a set of water sprays to wash the coarse coal as it passes across the …

Selection Tips for Vibrating Screens
Whether it's used on the clean coal or refuse side, the static sieve on a DNR application should recover 85% of the magnetite, Woodie explained. If it's not sized or designed correctly, the vibrating screen will not be able to return the media to the heavy-media circuit fast enough. It will carry over to the dilute side.
