Buying and selling raw and semi-raw minerals is one of the main parts of the supply chain of industries, which includes the exchange of materials such as iron ore, copper, bauxite, limestone and phosphate. These materials are used directly or after primary processing (semi-raw) in steel, cement, chemical and agricultural industries.

Trade of raw and semi-raw minerals has contributed to the development of domestic industries, exports and sustainable supply of resources needed by industries and plays an important role in economic growth and industrial development.
