Coal Processing Methods
Other Coal Processing Methods. Many methods to process coal other than the foregoing have been suggested, and some have been tested in laboratory and pilot plant scales. Because coal is so cheap, less than ¼ cent per pound at the mine, it is a potentially attractive raw material for many uses.
What are the types of coal? | U.S. Geological Survey
There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard …

A process flow diagram for a typical coal cleaning plant is presented in Figure 11.10-1. In the initial preparation phase of coal cleaning, the raw coal is unloaded, stored, conveyed, crushed, and classified by screening into coarse and fine coal fractions. The size fractions are then conveyed to their respective cleaning processes.
Coal
Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity.
