The history of Aluminij d.d. Mostar began in the first years of the 20th century, with the discovery of bauxite ore deposits in Herzegovina and the subsequent exploitation of the resource. After the end of World War II in 1945, a new company was created, Bauxite Mines Mostar, with the goal of exploring, exploiting and transporting bauxite commercially. It was this first company that carried out the initial construction studies for aluminium smelters were conducted, the birth of the aluminium industry that was to come. In 1969, the Bauxite Mines Mostar Company merged with Energoinvest Sarajevo to form a new organisation focused on aluminium production.
The Government of the Socialist Republic of Bosnia and Herzegovina tasked the group with maximizing the potential of the resources in the region and develops a new facility that could turn Mostar into a global aluminium producer. This was achieved by 1975, as regular aluminium production began in the new Alumina Factory. This successful development was based on cooperation between Energoinvest and the French company Pechiney. The Alumina and Bauxite mines merged to form a new company in 1977, becoming Aluminij d.d. Mostar, and the blueprint for the company as it is known today. As aluminium production became established, the aluminium factory joined the organization in 1981.
With government control, between 1981 and 1990 the company went through several structural and name changes, reflecting the economic and political situations of the time. Finally, in 1990 Aluminij d.d. Mostar was separated from Energoinvest, keeping its name that by this time had become a well-recognized brand with a pristine reputation. Since that separation, Aluminij d.d. Mostar has become the leading aluminium producer of Bosnia and Herzegovina, and a core driver of the economy, providing employment and investment that has shaped life in the Herzegovina, Bosnia and Dalmatian Region.
