Coal is a sedimentary rock, and bituminous coal frequently contains "bands," or strips, of different consistency that mark the layers of plant material that were compressed. Bituminous coal is divided into three major types: smithing coal, cannel coal, and coking coal.

In active mining regions, bituminous coal is the most abundant coal. It has a a moisture content of less than 20 percent and a heat content range between 21 to 30 million Btu per ton in a moist, mineralmatterfree basis.

The materials specifically covered by these standards can be in the form of lump coke, pulverized coal, bituminous coal, coke and coal ash, reformed gas, and polishing and etching coal. These standards also include the thermophysical property tables for methane, ethane, .

Most of the major coalfields around the world have been developed as a result of similar types of tectonic environment. ... the composition of the ash of the coal that made the coke ...

The composition of coal depends on the conditions in which it was formed, and in some cases, a lowrank coal may be of a higher grade than a highrank coal. Though additional ranks of coal exist, as blacksmiths, we are concerned mainly with these three: lignite, bituminous and anthracite.

Bituminous coal (all coal) forms from the destructive distillation of plant remains under anaerobic conditions. It results from burial and compression, and the driving off of hydrogen and other volatiles leaving behind fixed carbon, with varying amounts of sulfur, and other elements.

Bituminous coal particles were recovered on the top of the liquid body in the range of from to 10 tons of coal for each gallon of reagent being used. EXAMPLE II A reagent concentrate having the following composition was prepared for use in a bath flotation or separation unit.
