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.

Coking Coal an overview ScienceDirect Topics

Coal India Ltd. has taken the initiative to set up six washeries with a total capacity of about 19 Mt/y for washing LVMC coal in BCCL and CCL (Table 7.9). The mode of setting up of five washeries in BCCL is under a BOM concept, i.e., build–operation–maintenance basis, through a global bidding process.

Fine Coal an overview ScienceDirect Topics

Conventional density-based fine coal cleaning technologies become ineffective when treating particle sizes approaching 0.15 mm. As such, ultrafine coal cleaning circuits that generally exploit differences in surface chemistry properties, e.g., a froth flotation process, are used to upgrade particles finer than 0.15 mm.
