To document a process flow, start by identifying the specific process you want to chart or diagram and break it down into a series of steps. Make a visual representation of these steps through a flowchart. Use different shapes and symbols to depict process steps, decision points, and connectors, then label each element properly.

This is a dull black coal with a higher heating value than lignite that is used primarily for generating electricity and for space heating. Most subbituminous reserves are located in Montana, Wyoming, Colorado, New Mexico, Washington and Alaska. Bituminous: Even greater pressure results in the creation of bituminous, or "soft" coal.

The coal delivered from the mine that reports to the coal preparation plant is called runofmine, or ROM, coal. This is the raw material for the CPP, and consists of coal, rocks, middlings, minerals and contamination. Contamination is usually introduced by the mining process and may include machine parts, used consumables and parts of ground ...

What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the RunofMine (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.
