Dry coal separation with the air dense medium fluidized bed (ADMFB) is an effective method for coal utilization and environmental protection. In this study, feed particles with various components were adjusted by controlling the number of middle density particles (Gmiddle).
Dense media separation utilises a medium with a density in between the density of the ore and the gangue (commercially worthless) particles. When introduced to this medium, particles either float or sink, depending on their density, as relative to the medium.
11/1/2001· Dry beneficiation of coal with an air dense-medium fluidized bed is an efficient coal separation method, which uses a gas-solids fluidized bed as the separating medium, contrasting with the conventional methods of coal preparation using water as medium as in jigs.
3.19.2.2.1.2 Dense-medium vessels. Dense medium separation, which is performed in a dense medium, is separating particles based on their densities. Troughs, baths, and drums are effectively used for coarse coal cleaning under the influence of gravity alone. Coal is immersed in a medium that has a density between the density of coal and mineral material.
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. A
The air dense medium fluidized bed dry coal separator uses gas-solid phases as the dense medium for coal separation, where the solid phase is magnetite powder. When fluidized, the state of the gas-solid phases of the bed performs like a fluid, and the heavy and light materials are separated by their densities. There are several factors influencing the
Dense medium separation (or heavy medium separation (HMS), or the sink-and-float process) is applied to the pre-concentration of minerals, i.e. the rejection of gangue prior to grinding for final liberation.

An effective means of dry coal beneficiation is offered by our STEINERT XSS T X-ray sorting system based on ‘dual energy’ x-ray transmission. This allows ash content to be reduced without the use of water, while specific contaminants such as sulphur can be accurately removed.
The over-dense medium is returned to the over-dense medium sump and distributed to the dense-medium washing circuits as make up. Magnetic separator tailings are used as product rinsing water.Considering the overall economics of steel-making, it was thought to reduce the composite clean coal ash at the washeries from 17% to 16% starting April 2003.
