Coking Coal or Metallurgical coal

Coking Coal or Metallurgical coal is used in manufacturing steel, where carbon must be as volatile-free and ash-free as possible. Coking coal is also heated to produce coke, a hard porous material which is used to blast in furnaces for the extraction of iron from the iron ore.

Non Coking Coal

Non Coking Coal does not have any caking properties and it is mainly used as thermal coal for power generation. It has a higher ash content and also used in industries like cement, fertilizer, glass, ceramic, paper, chemical and brick manufacturing. Indian Non Coking Coal is classified on the basis of Gross Calorific Value (GCV) which consists of 17 GCV bands.

Coal Middlings

Coal Middlings are by-products of the coal washing / beneficiation process, as a portion of raw feed coal. It is used for power generation, brick manufacturing units, and cement plants. Typical specification Fixed Carbon : 45-46 %, Ash : 37-38 %, Volatile Matter : 15-16%

Coal Rejects

Coal Rejects are by-products of coal washing / beneficiation process after separation of beneficiated coal and middling, as a portion of raw feed coal. It is mostly used in FBC Boilers for power generation and domestic fuel (briquetting) units.

Anthracite Coal

Anthracite Coal is a hard, compact variety of mineral coal that has a high luster. Anthracite ignites with difficulty and burns with a short, blue, and smokeless flame. It has the highest carbon count, the fewest impurities, and the highest calorific content of all types of coals, which also include bituminous coal and lignite. It is mostly used for chemical and metallurgical purposes. Crushed anthracite makes an excellent medium density filtration media and is also used for water filtration process.

Jhama Coal

Jhama Coal is characterized by high ash, low volatile matter and high fixed carbon. Jhama is usually dull, compact and hard in nature. In India, a large amount of Jhama Coal has been found in the Damodar Valley Coalfields. Jhama is widely used in Lime Manufacturing, Ferro Alloys and Brick Manufacturing units.

Lignite Coal

Lignite Coal also referred to as brown coal, is a soft brown fuel and is considered the lowest rank of coal. It has characteristics that put it somewhere between coal and peat. Its carbon content varies from 40-55 % and it contains about 25-35% of moisture. The calorific value of lignite ranges between 6000-7000 B.Th.U (3300-3900 K.Cal/kg). Lignite is mainly used in power generation, and Brick Manufacturing units.

Metallurgical Coke

Metallurgical Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace where a uniform and high temperature is required. It is widely used at integrated plants as well as secondary steel / Pig Iron (Mini Blast Furnaces), Foundries, and Zinc & Copper Smelting.

Coal-Feneric

Nut Coke / Pearl Coke

Nut Coke / Pearl Coke have fixed carbon in high percentage. This low ash coke is highly used in Ferro Alloys, Blast Furnaces, Foundry works, Steel Industries and Non Ferrous foundries. The typical size of product is 5 mm to 30 mm.

Coal-Feneric

Breeze Coke or Coke Fines

Breeze Coke or Coke Fines refers to the fine sizes of coke, usually less than 10mm. It is generated after screening operation where pieces and dust too small for steel making are removed. Coke breeze is either reused on site (e.g. in the sinter plant) or disposed as a by-product.  The 0-3 mm is the most favourable particle size for coke breeze in the sintering process. It is used in Cement Industry, Refractories & Sintering Operations
