for successful production


AlumoFluor is an inorganic compound in powdered form and is classified as a top – quality product containing min. 96% of active substance.

AlumoFluor is low-density aluminium fluoride. It is produced using hexafluorosilicic acid, the product extracted during phosphoric acid production process, and neutralizing it with aluminium hydroxide.


It is mainly used as a catalyst for the production of primary Aluminium metal.

Aluminium fluoride essentially lowers the melting point of the alumina feed. Together with cryolite, it increases the electrolytes conductivity of the solution, reducing the electric power consumption which leads to the reduction of production costs of aluminium.

Depending on the quality of AIF3 as essential catalyst, the quantity of 10-25kg is required for production of 1Mt of Aluminium.

Production process

AlumoFluor is a low-density aluminium fluoride. It is produced druing phosphoric acid production process where hexafluorosilicic acid is subsequently neutralized with aluminium hydroxide.


AlumoFluor is classified as a top – quality product containing min. 96% of active substance.

Environmental Friendly Production

AlumoFluor is manufactured in accordance with the Green Tech principles:

As a raw material, we use a by-product of chemical industry, the reuse of which creates new value and protects the environment

The technology uses electricity produced from CO2 neutral source (Đerdap Hydropower Plant)

LPG energy is also used as one of the cleanest energy sources (liquefied gas)

Reliable Supplier

The production of AlumoFluor officially started in mid-February 2021 .

Prahovo is located on the bank of the river Danube, right on the threepoint border of Serbia, Romania and Bulgaria.

Transhipment capacity of Prahovo Port is over a million and a half tons per annum.

River transport

Towards the east, the Danube connects Prahovo directly to the Black Sea (626 km) and Constanta, the most important harbour in the region, with a reloading capacity of 100 million tonnes per year.
Northward, the Danube connects Prahovo to the countries of the Danube basin, all the way to Germany. Through the Rhine-Main- Danube Canal it is connected to Rotterdam and the North Sea, as well as Mannheim.

Rail transport

There is a well-developed rail infrastructure with a number of industrial tracks within the port, and the whole existing complex is connected to the Serbian Railways system and the international rail network.

Road transport

Prahovo is connected with around 50 km of road to Vidin in Bulgaria, and Calafat in Romania, both of which are important road and rail hubs on the European Corridor 4. A 150km highway also connects it to the European Corridor 10, which links Serbia to other European countries.
