Peat is the youngest of all coals. This means the vegetation from which it came was buried a shorter time than that of other coals. Peat has the least heat value of all solid fuels.Lignite is sometimes called brown coal. It's a little older than peat and has more heating value.Bituminous coal has the highest heating value of all solid fuels.Anthracite coal is the hardest of all coals and the oldest in nature.Coal may also be designated into groups by its ultimate use: Thermal, MetallurgicalThere are three groups (Low, Medium and High Volatile Coal) based on how it can be coked.

A diamond is the hardest mineral. However diamonds vary in hardness with South African diamonds being harder than Australian ones.
No. On the Mohs Scale of hardness, the hardness comparisons are exactly opposite. Talc is rated as 1 -- soft, and diamond is rated as 10 -- hard, in fact, the hardest rating.
What do you mean? the hardest element? Carbon in the form of diamond is the hardest substance in the world, followed i think by tungsten which is what they use to make lightbulb filaments with!
Anthracite is metamorphosed bituminous coal, a coal with the highest percentage of carbon of the coal varieties.
Strongly caking coals, which yield a solid product (coke) with properties suitable for use in a blast furnace, are called coking coals. All coking coals are caking, but not all caking coals are suitable for coke making.

Diamonds are the hardest mineral and the agate is the secod hardest mineral.
Diamonds are the hardest known substance
I would have to say Steven is the hardest, all of them are easy for me, but Steven is the hardest I have faced, and he is easy peasy lemon squeezy. I would have to say Steven is the hardest, all of them are easy for me, but Steven is the hardest I have faced, and he is easy peasy lemon squeezy.
Yes, all coals contain traces of uranium.

Coals of Fire was created on 1915-01-27.
Usually, it's 120 coals. If you are wearing the Seer's headband 1, it's 140 coals. With the Seer's headband 2, it's 168 coals. With the Seer's headband 3, it's 196 coals.
Coals as straight or in blend which on carbonization produce hard coke are known as coking coals. Depending upon coking capacity, coking coals are divided into prime or hard coking coal, medium or soft coking coals and weakly or semi-soft coking coals. The coking coals are classified based on CSN, LTGK coke type, gieseler fluidity, vitrinite contents, mean maximum reflectace of vitrinite etc. On the other hand, coals which on carbonization produce powery mass are known as non-coking coals. Coals having CSN 0-1 and LTGK coke type of A and B are non coking coals. Dr. Tamal Kanti Das DGM, RDCIS, SAIL, Ranchi, India
