Metallurgical Coal There are two main types of coal, energy coal and metallurgical coal. Metallurgical coal is used in steel production, making it a critical building material for the construction of high-rise buildings and infrastructure like bridges.
Metallurgical coal, also known as coking coal, is a low sulfur, low ash, and low phosphorus grade of coal. It is used to produce high-grade coke, which is an important reactant for manufacturing of primary steel in the blast furnace process.
Apr 02, 2010· Coal-based pitches are predominantly byproducts of metallurgical coke operations in recovery-type coke ovens. The volatile products from the coke oven are recovered and processed, in simplest terms, into gas, light oils, and tar.
It is further divided into Thermal and Metallurgical types. Thermal coal is also known as steaming coal as it is primarily used for producing steam for electricity, whereas metallurgical coal is also known as coking coke as it is used in the production of coke for iron and steel industry. Anthracite Coal – this coal is of highest rank. It is ...
organic portions of coal are categorized as macerals, the various types of coalified plant material. Banded coals are referred to as attrital or splint coal types, whereas the non-banded coals are cannel and/or boghead coal types. Each has its own characteristics and …
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.
TYPES OF COAL, THEIR PROPERTIES AND USAGE COKING COAL: These coals, when heated in the absence of air, form coherent beads, free from volatiles, with strong and porous mass, called coke. These have coking properties Mainly used in steel making and metallurgical industries Also used for hard coke manufacturing SEMI COKING COAL:

Coking Coal A Strategic Market Outlook to 2020 What is the outlook for the coking coal supply/demand balance? What will happen to future coking coal price settlements? What are the implications of reduced carbon emissions on the industry? Is there going to be sufficient coking coal to meet projected steel production rates?
Global steel production is dependent on coal. 74% of the steel produced today uses coal. Metallurgical coal – or coking coal – is a vital ingredient in the steel making process. World crude steel production was 1.6 billion tonnes in 2017.
Different Types of Coal It is important to be aware that "coal" can cover a variety of finished products of differing values and requiring different treatment. The main division is between "coking" coal and "energy or steaming" coal.
The coal mined in the Southwest ia Coalfield is well suited for a variety of primary uses including electricity generation (steam coal), manufacturing coke (metallurgical coal), and supplying other industrial (non-coke), commercial and institutional users.
Metallurgical coal is a special type of coal used to make metallurgical coke. There are two types of metallurgical coal used to make coke: hard coking coal and semisoft coking coal. According to Grande Cache Coal, these types of coal are ideal for coke because they melt, swell and re-solidify when placed into a superheated furnace.

Coal is a sedimentary black or dark brown rock that varies in composition. Some types of coal burn hotter and cleaner, while others contain high moisture content and compounds that contribute to acid rain and other pollution when burned.
Mining 101 August 30, 2012 The Basics There are four basic types of coal: Lignite, subbituminous, bituminous and anthracite. Lignite is the lowest rank of coal with the lowest energy content. Lignite is crumbly and has high moisture content. ... Metallurgical coal mined in West ia represents some of the highest quality coal found anywhere ...
Metallurgical coal or coking coal is used in the process of creating coke necessary for iron and steel-making. Coke is a porous, hard black rock of concentrated carbon that is created by heating bituminous coal without air to extremely high temperatures.
Many coal properties are in part determined by rank, including the amount of heat produced during combustion, the amount of gaseous products released upon heating, and the suitability of the coals for liquefaction or for producing coke. Coal types Macerals. Coals contain both …
