The method of aluminum production or the life cycle of aluminum semi – finished products in two ways of production of primary or secondary metal (recycled) in the aluminum industry is given. Primary metal is a metal obtained directly from the mining route, and secondary or recycled metal is a metal obtained by recycling waste. The ratio of each ring to the loop before and after, depending on the type of chain, through inter-firm trade or vertical integration links of different parts of the firm.
The method of producing aluminum from bauxite is to extract aluminum from bauxite as aluminum oxide (aluminum), so the main source of aluminum is bauxite. Also, the value chain of aluminum products, such as aluminum profiles from mines to final products, includes the following main links:
Demand is one of the most important factors in the growth, survival or disappearance of industry and trade. Demand for primary ingots is a reflection of the supply of upper rings and the demand for downstream rings.
Also, according to the geological definition of bauxite, aluminum ore is called bauxite, but according to its economic definition, bauxite is a mineral that not only meets the requirements in the geological definition, but also produces aluminum in geographical and economic terms. Be economical.
Bauxite is exploited to varying degrees in different countries and is made of aluminum; Therefore, its quality varies depending on the weather, type of technology, reserves, economic and even political conditions, and many countries also produce aluminum from low-quality bauxite. One of the most important indicators of the economics of aluminum production from bauxite is the consumption of caustic soda for its production, which has a high price in the process of aluminum production.
The value chain of aluminum materials and products, from mining to final products, has six main links in two areas: anterior and upstream (extraction, aluminum and smelting of aluminum) and posterior and downstream (semi-finished, finished and recycled). Also, the chain of production of aluminum or the life cycle of semi-finished aluminum products takes place in two modes: production of metal through raw metal or melting of aluminum waste. The relationship of each ring with the previous and next loops, depending on the type of value chain, is realized through inter-firm trade or vertical merging of different parts of the firm.
