coal washing, magnetic separation & processing

coal washing, magnetic separation & processing

Magnetite is suited to coal washing due to its: High density; and; Ability to be recovered via magnetic separation for recycling and reuse. A Durable Mineral. The dense medium separation process used in most coal washing and magnetic separation plants requires …

magnetite recovery in coal washing by high gradient

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

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 relative density and affect …

An analysis of medium losses in coal washing plants. sripriya R. IntroductionDense-medium (magnetite in the case of coal), a slurry/ suspension having a relative density intermediate to that of valuable mineral and gangue, is generally used as the medium of separation in most coal preparation plants. The medium, being costly, plays a crucial role in determining the economics of any preparation operation

magnetite heavy media: standards and testing procedures

magnetite heavy media: standards and testing procedures

Magnetite heavy media processes are accurate, efficient and easy to control separators, capable of producing high quality clean coal. Magnetite recovery circuit operation and magnetite consumption are the main reasons for high capital and operating costs. Over the last two decades, several countries have been actively involved in establishing magnetite specifications for coal heavy media circuits and in …

IntroductionMagnetite is used as a high density material from which together with water a dense medium is prepared. The high density material must meet at least several conditions, such as availability, low cost, sufficient density, abrasion resistance, and may not react with treated raw material and may not be soluble in water as well. The dense medium must have at least several properties such as high …
