Applications of minerals in the industrial production, agriculture and tertiary industries include: (1) Use of mineral ingredients: (a) In the metallurgical industry for extracting useful elements from minerals and smelting them into metals for industrial uses. For example, the extraction of iron metal from magnetite and haematite is an important metallurgical process. Other examples are the extraction of lead from galena and the extraction of copper from chalcopyrite and bornite. In addition to the main elements, minerals also contain several trace elements, such as chromium, indium and germanium, in sphalerite ore. These trace elements are called dispersed elements, and they are also extracted during the extraction of the main metals. (b) As chemical raw materials. For example, fluorite can be processed into hydrofluoric acid, and pyrite can be used as a raw material for making sulphuric acid. (c) For agriculture, such as for the production of fertilizer for agricultural production....
