of dirt, coal fines and moisture, which eventually add to the problems of coal beneficiation. The fine coal circuits in coal washeries are intricate, needing close attention and careful operation. Increase in fines in raw coal feed to washeries also adversely affects the material balance in fine coal circuits of the currently operating plants ...
The first dry coal beneficiation plant in the world with air-dense medium fluidized bed has been established by CUMT for beneficiation of 50 6mm size fraction coal. The flowsheet is shown in Figure 1 and the separator schematic is shown in Figure 2.
Pollution associated with coal washeries for beneficiation of coal: Coal seam in some of the countries has drift origin, resulted in intimate mixing of mineral matter with coal, giving rise to more ash content. Coal washeries are to reduce ash content in coal. For coking coal and non-coking / thermal coal quality improvement, coal washeries are ...
Beneficiation, Washing, Cleaning, Preparation, Processing. In this we focus on the beneficiation of coal, in the next topic we will look at the processing of metallic ferrous ores. The purpose or beneficiation of coal is to reduce the concentration of unwanted material or gangue which in the coal industry is referred to as mineral matter or ash.

proven capable of processing coal down to fine sizes, it is generally applied only to coal coarser in size than 0.5 mm. Beneficiation of fine coal, nominally below 0.5 mm, with dense-medium cyclones was implemented as long ago as 1957 and cyclones are still being used to process fine coal
beneficiation. These aspects are classified as (i) understanding the densimetric profile of the available ore body, (ii) understanding the properties of the heavy medium utilised at the plant to beneficiate the ore, and (iii) the automation and modelling of the processing plant in order to maximise plant efficiency.
