main article. Anthracite is a dark black form of coal and the highest quality coal.It is very hard, has a low moisture content, and a carbon content of nearly 95%. When burned, anthracite can reach a very high temperature.In addition, anthracite is usually the oldest type of coal, having formed from biomass that was buried 350 million years ago.

Briefly, coking coal is a hard coal with the quality that allows the production of coke to be suitable for supporting a blast furnace charge. On the other hand, different from coking coal, non-coking coal, also commonly known as thermal coal or steam coal [3], is all other hard coals which are not classified as coking coals.

COAL RANK Anthracite coal is a dense, hard rock with a jet-black color & metallic luster. It contains between 86% and 98% carbon by weight, & it burns slowly, with a pale blue flame & very little smoke Bituminous coal (in Indiana), contains between 69% & 86% carbon by weight Sub-bituminous coal contains less carbon, more

Metallurgical coal, also known as met and coking coal, is a naturally occurring sedimentary rock found within the earth's crust. Met coal encompasses a wide range of quality grades including hard coking coal, semi-hard coking-coal, semi-soft coking coal and pulverised coal for injection (PCI). All are used to make steel.

Coking coal has a relatively low heating value due to its higher impurity content, making it less efficient for direct combustion. In contrast, thermal coal has a higher heating value, making it suitable for electricity generation in coal-fired power plants. 3. Uses. Coking coal is primarily used in the production of steel.

For a longer grinding time, two coals become fine, and yields of anthracite coal in products increase gradually. If the grinding time is over 240 s, yields of anthracite coal in products become stable. For the mixture of 1:3, yield of anthracite coal varies from 25% of 0 s to 32.61% of 300 s, with the increase of 7.61%.

Coking Coal. Coking coal (or metallurgical coal) is a bituminous coal with a suitable quality that allows the production of metallurgical coke, or simply named coke. Coking coal has a higher carbon content than steam coal, as well as a lower level of sulphur, phosphorous and alkalis (World Coal Institute 2009).

Coke is made of a blend of typically three to seven coking coal grades. Coal grades have different properties: •. physical properties (density, grain size, petrography, ash, volatiles, moisture) •. chemical properties (P, S, K and Na contents, ash composition) •. coking properties (plasticity, shrinking, swelling) •.

Coal properties vary depending on how much carbon is in the coal (coal rank). Black coal is so called because of its colour; it varies from having a bright, shiny lustre to being very dull, and from being relatively hard to soft. The term 'black coal' is used in Australia to refer to anthracite, as well as bituminous and sub-bituminous coals.

a. Lower carbon content: Non-coking coal generally has a lower carbon content compared to cooking coal, typically ranging from 40% to 70%. b. Higher ash content: Non-coking coal has a higher ash content, which means it produces more ash residue when burned. This makes it less suitable for the production of coke.

A coking coal is that coal which on heating in absence of air leaves a solid residue. non-coking coal also leaves a solid coherent residue which may not possess the physical & chemical properties of the coke. The non-coking coals are those coals which may form a solid-residue but may not be suitable for manufacture of coke.
