- Coal gas: Coal gas is a mixture of caloric gases consists of hydrogen, carbon monoxide, methane and volatile hydrocarbons with small amounts of noncaloric gases carbon dioxide and nitrogen as impurities. Coal gas is used mainly for production of chemicals and as fuel source for coking, industrial boilers, electricity generation and household use.
- Tar (light oil): Tar is a viscous black liquid derived from the destructive distillation of organic matter. Most Tar is produced from coal as a byproduct of coke metallurgical production but it can also be produced from petroleum, peat or wood. Tar is used mainly for production of chemicals, plastics, pharmaceutical products and dyes.
- Crude Benzene: Crude benzene is a chemical by product resultant from baking of coke. Crude benzene is used mainly for production of chemicals, plastics, pharmaceutical products and dyes.
- Ammonium sulfate: is an inorganic chemical compound commonly used as a fertilizer. It contains 21% nitrogen as ammonia and 24% sulfur as sulfate. Its molecular formula is closely related to Mohr’s salt an ammonium sulfate analogue with an iron atom within the compound. Ammonium sulfate is used largely as artificial fertilizer for alkaline soils.

- Coal slime: Coal slime is a new by-products resultant from coal washing process. Coal slime is sold to power plant as it serves as raw material for energy source.
- Middlings: Middlings is a new by-products resultant from coal washing process. Middlings is sold to power plant as its raw material for energy source.
