    Metals are easier to recycle than plastic and they retain their original properties, such as conductivity and hardness. Recycling uses up to 95% less electricity than producing metals from ores. Recycling costs less than extracting metals and can be profitable. Recycling creates less waste and reduces the number of sites that have to be mined.

     · These processes involved in the extraction and refining of the metal are called metallurgy. The ores of most of the metals should be brought to the Earth's surface for extracting metal from them. This process is called mining. Generally, there are three main steps involved in the process of extraction of metals.

     · The way we extract a metal from its ore depends on the position of the metal in the reactivity series. Carbon is used to reduce oxides of metals below it in the reactivity series. Metals above carbon in the reactivity series cannot be extracted from their oxides by heating with carbon. This is because the metal bonds to oxygen too strongly and the carbon is not reactive .
