2018 To differentiate between Coal and Hydrocarbons such as Petroleum with respect to their mere physical properties is not a difficult task even to the layman. Since Hydrocarbons are not limited to Petroleum only, difficulty arise to some people whether coal can also be classified as hydrocarbon or not.
Coke (fuel) Raw coke. Coke is a grey, hard, and porous coalbased fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a ...
Jigging is the process of particle stratification due to alternate expansion and compaction of a bed of particles by a vertical pulsating fluid flow. A single jigging vessel can treat large particles (up to 200 mm) at capacities approaching 680 tonnes (750 tons) per hour.
The coking coal must have the following; Low ash content Low Sulphur content Porosity factor Abrasive strength and hardness Coke Manufacturing Coke is created by heating metallurgical coal to around 2,000 degrees Fahrenheit. The coking process takes about 12 to 36 hours in the oven to complete.

7. 7 2. Box cut Box cut is the initial/first cut given for the physical development of a mine. The name 'Box cut' has been attributed to this cut as this cut generally looks like a top open box having an inclined floor and walls on three sides (front wall and two side walls) in case of opening up of subsurface deposits.

2. ACTIVATED CARBON Activated carbon is a form of carbon which could be produced from any carbonaceous material such as coal, rice husk, paddy husk, coconut shell, wood etc. Due to their low ash content, high carbon content and natural pore structure, coconut shells are ideal for producing high quality activated carbon. Activated carbon manufactured from coconut shell is considered superior to ...
Formation • The transformation of the vegetable debris to coal takes place in two stages: (a) Biochemical or peat stage: During this stage, the plant materials were attacked by various micro organisms. (b) Chemical stage or metamorphism: In this stage, the peat deposit buried under sedimentary deposits lose moisture and volatile components under the effect of high temperature and ...
