Coal preparation, or beneficiation, is a series of operations that remove mineral matter (i.e., ash) from coal. Preparation relies on different mechanical operations, which will not be discussed in detail, to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.
Thermal Coal Drying and Beneficiation Systems CVE-003989_Mining_Brochure.qxd:Layout 1 7/30/08 1:31 PM Page 3 thermal dryers are typically used for coals with a larger size fraction (such as run-of-mine coal). Vibration significantly assists in This setup results in a very high efficiency inert thermal coal drying system for high

indonesia coal drying plant. rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan. Gravity separation is the main beneficiation method of chrome ore, and the equipment is jigger, shaking table, spiral classifier, centrifugal concentrator and spiral chute, etc
Even today, traditional coal beneficiation is performed using coal washing with large amounts of water. It is then necessary to expend considerable energy drying the coal again. Moreover, in many regions of the world water is rare, and it is becoming more difficult for mines to obtain licenses for its use.
Microwave coal processing is a diverse area, which has the potential to aid in coal upgrading, cleaning and comminution, thus improving efficiency and reducing harmful emissions of coal usage.
The coal blend bulk density for coking processes can be adjusted by changes on particle size, i.e., the coal crushing level, or even drying or humidifying the coal, that are easily manipulated in the coal beneficiation.

Some variables, such as moisture and particle size, which are controlled or measured in the coal beneficiation process in steel mills, exert a strong influence on this feature. This study aims to understand the density variation of coal blends by the influence of moisture and particle size when using dry and wet bases.

4.2.1 Effect of particle size on charge bulk density. When particles are divided, the total surface area and the number of voids between the particles are increased (), reducing the density because the coal volume increases, justifying the results for an excessive crushing at 85% < 2.83mm.The reason for misunderstanding: the resolution limit of the human eye at a distance of 25 cm is 0.2 mm

The increased mechanization in the underground coal-mining industry has increased the volume of fine size coal and waste (refuse) in the mined coal. Processing of run-of-mine (ROM) coal is generally done using water away from mine and in some cases the coal has to be transported a long distance to the preparation plant. Dry processing of coal can be economical as it will not utilize water and
