Abstract

About 75% of all elements are metals. The majority of these are found as compounds, called minerals, in the earth. They are extracted in processes involving a number of chemical reactions. Only a few metals are found as the pure element. These are called native metals. They include gold, silver and copper, which were the first metals that people learnt to use.
