Coal

The discovery of the use of fire helped to distinguish humans from other animals. Early fuels were primarily wood (and char Coal derived from it), straw, and dried dung. References to the early uses of Coal are meagre. Aristotle referred to “bodies which have more of earth than of smoke” and called them “Coal-like substances.” (It should be noted that biblical references to Coal are to char Coal rather than to the rock, Coal.) Coal was used commercially by the Chinese long before it was utilized in Europe. Although no authentic record is available, Coal from the Fushun mine in northeastern China may have been employed to smelt copper as early as 1000 B.C. Stones used as fuel were said to have been produced in China during the Han dynasty (206 B.C.– 220 A.D.). Coal is an abundant natural resource that can be used as a source of energy, as a chemical feedstock from which numerous synthetic compounds (e.g., dyes, oils, waxes, pharmaceuticals, and pesticides) can be derived, and in the production of coke for metallurgical processes. Coal is a major source of energy in the production of electrical power using steam generation. In addition, gasification and liquefaction produce gaseous and liquid fuels that can be easily transported (e.g., by pipeline) and conveniently stored in tanks. Iran has many active Coal mines such as Tabas, Shemshak, Nayband, etc. So we can count Iran as one of the best Coal Suppliers of Middle East. Marjan Mineral Company can make commercial communities to export Coal to all around the world. Read more . . .


Coal Usages:
Coal is used worldwide in many day-to-day goods and services that we might sometimes take for granted in our modern society – such as electricity generation, steel production and cement manufacturing.

There are two main types of coal, which have different uses:
  • Thermal coal: mainly used for electricity generation.
  • Coking coal (or metallurgical coal): mainly used in the production of steel. Read more . . .
