50.5 EXTRACTION OF METALS- METALLURGY Chemistry

The process of extraction of metal from the concentrated ore depends upon the nature of the ore as well as the nature of impurities present in the ore. Before the concentrated ore is subjected to final metallurgical operations in order to get the metal in the free state, the preliminary chemical treatment may be necessary.

Where do metals come from

The first stage in making metals is to mine the ore-bearing rock. Sometimes huge amounts of ore are needed to make a small amount of metal – most copper, for example, exists in sulphide ores that contain as little as 0.25% copper. The metal then has to be extracted from the rock using furnaces and electrolytic processes.
