ISO 8833:1989(en), Magnetite for use in coal preparation

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 the presence of gangue minerals may lower the

Coal Washing, Magnetic Separation & Processing

The much sought after magnetite concentrate is primarily used for dense medium separation in coal washing and mineral preparation as well as a feed for iron ore. Magnetite is suited to coal washing due to its: High density; and. Ability to be recovered via magnetic separation for recycling and reuse.

US3737032A Coal preparation process and magnetite

A coal preparation process includes a dense medium coal separator which utilizes a magnetite media for separating raw coal from refuse. A sieve receives coal from the separator and is utilized to drain a portion of the magnetite media from the coal before the coal is passed into a new magnetite reclaimer wherein paddles agitate the coal causing abrasive contact between the coal particles to

Magnetite an overview ScienceDirect Topics

Magnetite is widely used in most dense-medium processes in the coal industry because of its higher specific gravity, stability in suspension, lower viscosity, and easy availability, recovery and reuse. To keep the suspension at the desired specific gravity and low viscosity, it is necessary to extract continuously some of the contaminating slimes from the medium. If the medium solid is magnetite, it

Determination of Magnetite in Dense-Medium Coal

Magnetite losses are generally significant in commercial coal cleaning plants using high-density medium techniques. It is common practice to monitor the cleaned coal, slurries, and refuse using a Davis Tube method in order to isolate and correct unnecessary losses. To ensure the Davis Tube yields correct results, tests were made by comparison with the magnetization determined with a Faraday

Magnetite and Carbon Extraction from Coal Fly Ash

In this study, enrichment methods for coal fly ash (CFA) from Omsk thermal power station No. 4 (TPS-4) were investigated. The magnetite and unburned carbon concentrates were obtained by magnetic separation and flotation methods. The wet magnetic separation used in the study increased the magnetite content in the magnetic fraction from 10.48 to 12.72 wt % compared to dry magnetic

Magnetite Recovery in Coal Washing by High Gradient

Fine magnetite mixed into a water suspension is commonly used in coal preparation to create a pseudo- specific gravity great enough to effect separations between coal and associ- ated impurities. The magnetite must not only be reclaimed but must also be cleaned to prevent coal and impurities from building up in the washing cir- cuit. The reclaimed coal fines have economic value. Studies have been

Properties of Magnetite used in the preparation plant Raw magnetite testing were not possible to be performed due to unavailability of equipment for testing on the Lab. We recommend for further test that a Dave’s Tube is granted by the Lab. The list of test that must be done is: the density of magnetite, its grain size composition, contents of magnetic particles in raw magnetite and properties of raw

THE CHALLENGE OF COAL PREPARATION

Coal preparation is the practice whereby raw coal is modified to a more preferred form to enable its utilization. The methods employed to achieve this preferred modification need to be cost-effective, while also being appropriate to the raw coal, the scale of production and the ultimate end user requirements. Since the cost of coal preparation is a measurable part of mine construction and mine
