Anthracite is a high-rank coal, representing a coal that has been subjected to the highest grade of metamorphism. Anthracite is shiny black, hard and brittle see Figure 2.8 and has the highest fixed-carbon content approximately 8698.Due to its low volatile matter 212, anthracites combustion process is slow. Most anthracites have low-moisture content about 36 and their ...

The term black coal is used in Australia to refer to anthracite, as well as bituminous and sub-bituminous coals Table 3.7. Black coal is higher in energy and has lower moisture content than brown coal. Brown coal, also called lignite, is a low-ranked coal with high moisture content that is used mainly to generate electricity.

The Specific Gravity - SG - is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature. It is common to use the density of water at 4 o C 39 o F as reference - at this point the density of water is at the highest.. Specific gravities - SG - for common solids and metals can be found in the table below
Anthracite Filter Media. Anthracite Filter Media is thoroughly selected from anthracite which yields the highest percentage of carbon. It is then hydraulically classified to reduce mineral matter and ash to a minimum, and finally screened and washed to ensure suitability for filtration purposes.
Sep 17, 2019 Coal type is a specific geologic classification based on the general appearance of coal. Most coals have internal layering, called banding. Coal types, and subsets of types, called lithotypes, are based on the presence or absence of banding, and the brightness or dullness of individual bands. Coal lithotypes are further divided into microscopic ...
