Wood, coal, paper and LPG are combustible substances which produce heat on burning. However, all combustible substances cannot be called fuels. Hence a fuel is a combustible substance that can be used to produce heat at a reasonable cost. Fuels contain potential energy that is locked within the chemical bonds of their constituent molecules, when they are burnt, a large part of this energy is released as heat.

The following changes take place during the process. a) b) Moisture is de riven away Impurities like S,P, As etc. des. 6/ c) Copper pysite is decomposed and both Cu2S and FeS are partially oxidised . 2 CuFeS2+02 ~ Cu2S+2FeS+S02 t 2FeS+302 ~ 2FeO+2S02t 2Cu2S+302~ 2Cu 20+2S02 t 3) Smelting - The roasted ore is now mixed with some sand and coke and is heated strongly in a blast furnace. A blast of hot air is led into the furnace from bottom. During smelting the following changes take place. a) Most of FeS present in the ore converted into ferrous oxide which forms slag with sand.
