Abstract: As it comes from the mine, coal is known as run-of-mine (ROM) coal and consists of a range of sizes from chunks to small particles mixed with some dirt and rocks. In most cases, this ROM coal needs some degree of preparation and beneficiation to meet certain market requirements as sizes, ash, sulfur, moisture, and heating values.

The U.S. coal industry serves a vital role in the nation's economy by producing fuel for more than half of its electricity. Despite the industry's importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between …
The coal flow, moisture variations and other conditions that can have an effect . on the coal stream or coal characteristics must be reviewed. The number of seams, coal types or blends to be used in the test must be established, and the widest range of ash and sulphur values must be selected. The mechanical sampling system should be inspected
