The African continent is unique in terms of reserves and quality of ore raw materials for the production of aluminum, one of the most important strategic metals, the growth of consumption of which is dictated by scientific and technological progress. Steel, aluminum and copper are the three main metals of global industrial production. Although iron remains the main structural material (it accounts for more than 90% of all metal products produced in the world), without non-ferrous metals, primarily aluminum and copper, it is impossible for the modern industry to function. The invasion of aluminum in technology at the beginning of the XX century was primarily due to the development of aircraft construction, and it rightfully earned the reputation of a" winged " metal. Today, it is used as one of the most important metals in the nuclear, chemical, electronic, construction industries, in the production of automobiles, radiators, and in the packaging industry.
