What we do
Creating aluminium
The pure form of aluminium does not naturally occur in nature,
so it remained largely unknown until as recently as 200 years ago.
Creating aluminium using electricity was first developed in 1886
and is still used to this day.
Bauxite mining
Aluminum production starts with the raw material bauxite, an aluminium rich mineral in the form of aluminium hydroxide. There are around 29 billion tonnes of known reserves of bauxite and at the current rate of extraction, these reserves will last us more than 100 years.

Alumina refining
Bauxite is crushed, dried and ground in special mills where it is mixed with a small amount of water. This process produces a thick paste. It is then collected in special containers and heated with steam to remove most of the silicon present in bauxites.

Reduction process
At an aluminium smelter, alumina is poured into special reduction cells with molten cryolite at 950°C. Electric currents are then induced in the mixture at kA or above, forcing the bond between aluminium and oxygen atoms to break.

Primary production
Primary production is cast into ingots. Shapes and sizes vary, depending on the needs of the clients. Once in the desired form, aluminium is then shipped to customers globally or used in the production of aluminium alloys.

Fabrication
Primary aluminium is developed into different products and various forms with wide applications. The most common uses of primary aluminum are extruding, rolling and casting. Aluminium’s unique characteristics allow for it to be shaped into a wide variety of uses and functions.

Recycling
Aluminium loses none of its core properties when recycled. Approximately 75% of all the aluminium ever made is still in use. What’s more, recycling aluminium requires 5% the amount of energy needed to make new material and it can take as little as 60 days.

Symbiotic combination of assets
Our assets are located in the heart of Siberia, next to Lake Baikal, the largest freshwater reserve in the world. This allows En+ Group to harness the unique potential of the Angara and Yenisey rivers. En+ Groups symbiotic combination of power generating and aluminium assets allows to set industry standards in operational efficiency. We are constantly expanding and upgrading our production facilities.
