Aluminium, unwrought; alumina

cpc code 4143 covers the production and trade of unwrought aluminium and alumina, which are essential materials for a wide range of industries. Aluminium is a lightweight, durable, and corrosion-resistant metal with a diverse range of applications, from construction and transportation to packaging and electronics. Alumina, on the other hand, is the primary raw material used in the production of aluminium, making this industry a crucial component of the global supply chain.

The production of unwrought aluminium and alumina involves several key steps. Alumina is typically produced through the Bayer process, which involves the extraction of alumina from bauxite ore. This process includes crushing, grinding, and chemical treatment to separate the alumina from the ore. Unwrought aluminium is then produced through the electrolytic reduction of alumina, a process known as the Hall-Héroult method. This involves the use of high-temperature electrolytic cells to extract pure aluminium metal from the alumina.

The main inputs required for the production of unwrought aluminium and alumina include bauxite ore, which is the primary raw material for alumina production, as well as electricity, natural gas, and other energy sources to power the electrolytic reduction process. Additionally, specialized machinery and equipment, such as crushers, grinders, and electrolytic cells, are essential for the various stages of production.

The primary outputs of this industry are unwrought aluminium and alumina. Unwrought aluminium is then further processed and used in a wide range of industries, including 4144 Aluminium, wrought, 4145 Aluminium alloys, unwrought, and 4146 Aluminium alloys, wrought. Alumina, on the other hand, is a key input for the production of aluminium, as well as other industrial applications, such as the manufacture of abrasives and refractories.
