Coke from lignite

Metallurgical Coal - Ram River Coal Corp.

Metallurgical coal is more scarce and valuable than thermal coal, so in practice metallurgical coal is rarely used to generate electricity. Metallurgical coal is also common-ly referred to as coking coal. Coking coal has physical properties that when heated cause it to soften, liquefy and then resolidify into a harder substance known as coke.

Coal for the Blacksmith

 · Mined from deeper mines than lignite, it burns much more cleanly. When burning coal in the forge, we keep a “stock pile” of wet coal on the sides of the fire. As it smolders, most of the impurities are burned away, leaving primarily carbon, in the form of what we call coke. Coke formed by heating bituminous coal in the forge
