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.

In year 1556, dolioform ROM Jigging Bath was used for mineral processing, since early 1800s it was applied into coal washing, and in 1950s, it spreaded all over coal mines in middle Europe. In year 1820, German professor Dr. Hartz developed ROM Jig to fixed screen piston jig, and it was used for minrral processing by pulsating water flow, in 1840 it was used for coal washing.
