The commercial processes of coal beneficiation are based on the differences in some physical properties of the pure coal and the impure coal (refuse). The difference in specific gravity is the basis for the largest number of coal beneficiation processes in which case they are termed as Gravity Concentration Processes. Depending upon the medium ...

The value of the fine coal necessitated the selection of the correct equipment for the gravity beneficiation of this coal. On the other hand, fine coal might be unwanted; it all depends on the coal, the market and the decision makers. Each technology in use for the processing of fine coal therefore has its own place in the process flow …

The process of enriching taconite ore involved grinding the ore to remove gangues and upgrading the iron ore (i.e., an ore beneficiation process). The resultant high grade ore is in the form of fine particles, as small as 0.1 mm or less, which are not suitable for sintering. This issue led to the development of the pelletizing process.

as on-site fuel. Coal has a wide range of moisture (2-40%), sulfur (0.2-8%), and ash content (5-40%). These can affect the value of the coal as a fuel and cause environmental problems in its use. The depth, thickness, and configuration of the coal seams determine the mode of extraction. Shallow, flat coal deposits are mined
