Minerals and ores Mineral wealth has an important place
among natural resources. Minerals are formed by various processes taking place
in the environment.
The rocks on the earth are mainly made of minerals. These
minerals can be obtained by mining. Only a few metals like, for example, gold,
silver, copper, platinum and bismuth occur in the free state in nature.
A majority of the metals occur in the form of compounds.
Minerals that contain a high proportion of metal are called ores.
