This method is used for the extraction of lead, zinc, iron, copper, manganese and tin. In this method, the roasted oxide ore is mixed with carbon (charcoal, coal or coke) and a flux, and is heated to a very high temperature in a suitable furnace. Carbon reduces the oxide to met..

Reduction of Ores - The oxide obtained by calcination or roasting is then reduced by either carbon or hydrogen. Carbon is usually used in the form of coke, or carbon monoxide. Not all metallic oxides can be reduced by carbon or carbon monoxide. Thus, in order to extract metal from its ore..

The method of reduction of an oxide is based on the position of the metal in the reactivity serie..

This method is used for oxides of moderately reactive metals. Coke is an inexpensive reducing agent and is most widely used. ..

Balancing Oxidation-Reduction Reactions - There are two very important methods for balancing oxidation-reduction reactions. These are: Oxidation number method Ion-electron meth..
