Coal preparation or coal beneficiation comprises a number of actions to treat ROM coal to ensure a consistent quality and to enhance its suitability for particular enduses. With the increasing usage of lignite and subbituminous coal (both classified as LRC), reducing the level of intrinsic moisture either by application of drying technologies or coal blending, is becoming an important aspect

Coal preparation, or beneficiation, is a series of operations that remove mineral matter (, 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.

Coal Beneficiation Coal beneficiation is a process by which the quality of raw coal is improved by either reducing the extraneous matter that gets extracted along with the mined coal or reducing the associated ash or both. Two basic processes of beneficiation: Drydeshaling: Noncoal or shalycoal is removed without using any liquid media.

For sulfide ores, a different process is taken for beneficiation. The ore needs to have the sulfur removed before smelting can begin. Roasting is the primary method of separating, where wood was placed on heaps of ore and set on fire to help with oxidation. 2 Cu 2 S + 3 O 2 2 Cu 2 O + 2 SO 2
Dry coal beneficiation methods were widely used at the beginning of 20th century. For example in Europe dry coal separation methods were used in England (1925), and later in Germany, Poland and
Abstract. A process is described for modifying the surfaces of oxidized coal and beneficiating the coal, the process comprising the steps of: (i) subjecting coal having oxidized surfaces to high shear agitation in water; (ii) desliming the coal mixture resulting from step (i); and (iii) introducing the deslimed coal mixture resulting from step (ii) to froth flotation beneficiation, the froth

#0183;#32;Coal Grain Analysis (CGA) is an optical microscopic imaging method that is used for routine coal petrography assessments (maceral composition and coal rank) and for obtaining compositional information on individual coal grains. This method determines the number of mineral inclusions within the particles and is a good complement to the tree flotation and the washability by size information
