👉 Bituminisation, also known as bituminous or coal tar, is a chemical process that converts natural coal into a more durable and less toxic form of coal. The process involves heating coal in an oxygen-rich environment to a temperature above its melting point, which causes it to undergo a transformation called bituminization. This transformation results in the formation of a hard, brittle, and resistant material known as bituminous coal, which is then subjected to a series of treatment processes to improve its quality
