Aluminium production starts with the raw material bauxite, a
clay like soil type found in a belt around the equator. The bauxite
is mined from a few meters below the ground
The bauxite is then transported to plants where the clay is
washed off and the bauxite passes through a grinder
Aluminium production can also start with the raw material
nepheline, a hexagonal mineral that is a usually glassy crystalline
silicate of sodium, potassium and aluminium common in igneous
rocks

3 Alumina, or aluminium oxide, is extracted from the bauxite through
refining where alumina is separated from the bauxite by using a hot
solution of caustic soda and lime

filtered,
The mixture is
heated
and the remaining alumina is dried to a white powder
Alumina can be extracted via the Nepheline Process. Nepheline ore is
first sintered with limestone. The resulting sinter cake is crushed,
ground and leached, and alumina hydrate precipitated by
carbonation. The alumina hydrate is washed, dried and calcined to
produce alumina
Alumina production¹

5 Alumina is used to produce aluminium. Electricity is run
between a negative cathode and a positive anode, both
made of carbon. The anode reacts with the oxygen in
the alumina and forms CO2
6 The result is liquid aluminium, which can now be
tapped from the cells. The liquid aluminium is cast into
extrusion ingots, sheet ingots or foundry alloys

Projects to increase self-sufficiency in materials (>100% in alumina, ~80% bauxites and nephelines, ~90% in pre-baked anodes)³, efficient midstream and diversified product mix
•
1st stage of Dian Dian bauxite mine in Guinea was launched in June 2018
•
Friguia alumina complex was relaunched in June 2018 and will increase alumina output (600 ktpa)
.
Volgograd anode plant (104 Ktpa) with own calcined coke production capacities (95 ktpa) was test-launched in August 2018
•
New calcined coke production capacities at Irkutsk smelter (89 ktpa) were launched in August 2017
.
Taishet anode plant (1st stage - 217 ktpa) was launched in 1H20
Source: Company data.
1) Bauxites and alumina are mainly delivered to Group companies and minor portion goes to third parties. 2) Bauxites production in Russia including nepheline ore volumes. 3) As of 31.12.2020.
