Dry coal beneficiation. Dry coal beneficiation processes were widely applied in Europe and the United States during 1930–65. However, they were later abandoned largely because the separation was not accurate, the available technology severely restricted feed size and throughput, and moisture presented a major inhibiting …

mined coal or reducing the associated ash or both. Two basic processes of beneficiation: – Dry-deshaling: Non-coal or shaly-coal is removed without using any liquid media. – Wet process: Coal is crushed to smaller size and put in a liquid media of adjustable specific gravity to separate the lighter coal (low ash) from heavier coal (high ash).

The operating gas velocity is an important parameter for regulating coal beneficiation process. Fig. 2 shows the effect of gas velocity on the segregation degree and it is illustrated that the segregation degree of clean coal and gangue particles is greater at middle gas velocities of 1.2-1.3U mf.Although the segregation degree at 1.3U mf is …

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.
