What is tar and pitch made of?

tar and pitch, viscous, dark-brown to black substances obtained by the destructive distillation of coal, wood, petroleum, peat, and certain other organic materials. The heating or partial burning of wood to make charcoal yields tar as a byproduct and is an ancient method for the production of both tar and pitch.

How is Coke obtained?

Coke is obtained by destructive distillation of charcoal or coal in the furnace Destructive distillation is the chemical process involving the decomposition of coal or charcoal by heating to a high temperature in the absence of air or in the presence of limited amounts of oxygen.

Which is used for extraction of metals?

An ore is a mineral that contains enough metal to make it worth extracting the metal. Carbon can be used to extract metals from some metal oxides. A metal can either be reduced or oxidised in a reaction.

Which product of coal is used as reducing agent in the extraction of metal?
