First, it is pre screened by a circular vibrating screen with a sieve opening of 50 mm. +50mm materials and extra large gangue enter the crusher and are crushed to 50mm, and then transported to the coal washing workshop together with -50mm raw coal that under the vibrating screen.

Coal Beneficiation an overview ScienceDirect Topics

Currently, the wet coal beneficiation process is the predominant method for coal upgrading. The wet beneficiation processes include heavy media separation, cyclone (water only), froth flotation, and spiral separation [23,24]. The use of these technologies depends on the particle size of the feed and the quality of the product required.

What Is Coal Preparation? Energy.gov

2013-2-21  What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved.
