Fine coal refuse is less than 2 mm (No. 10 sieve) and is usually discarded in slurry form. Approximately 75 percent of coal refuse is coarse and 25 percent is fine. Coarse coal refuse is referred to as colliery spoil in the United Kingdom. Some 109 million metric tons (120 million tons) of coal refuse are generated each year in the United States.

For example, field studies indicate that the froth flotation process, which is normally used to treat minus ( mm) fine coal, often recovers less than 65 to 70% of the organic matter in this size range. Fine coal separation processes are also inherently less effective in removing pyrite than that of coarse coal .

If Beard Technologies is successful in recovering fine coal using the advanced separation system, many other companies could follow suit. The Energy Department estimates that 30–50 million tons of coal fines are discarded annually into impoundments because of the high cost of processing fine coal. This adds to the more
