Coal can be categorised into various types namely lignite, bituminous, sub bituminous and anthracite. Lignite is considered the lowest grade of coal, anthracite being the highest because of its highest heating value and highest carbon content (up to 97%).

Coal formation began to develop about 300 million years ago, during the time of Carboniferous period. This period witnessed wide, shallow seas and dense forests. The seas occasionally flooded the forested areas, thereby trapping plants and algae at the bottom of a swampy wetland. Some new plants grew, while some died and fell into the swamp waters. With time, thick layers of dead plants rotting in the swamp compounded and got buried and compressed under the weight of overlying mud and vegetation.

The iron age is defined as the prehistoric time which succeeded the bronze age and had witnessed the predominance of ferrous metallurgy. Modern archaeological evidence suggests the commencement of large-scale production of iron in and around 1200 BC, marking the end of the Bronze Age. This age is largely characterized by the mass production of tools, […]
