Conference Format

The hybrid format of the conference will enable your participation irrespectively if you travel to Lyon or must stay at home. The difference between on-site and online participation is:


  • On-site participants of the conference will be able to take full benefit of regular ICSOBA conference, including downloading the papers and presentations before the opening of the conference, participation in technical sessions, exhibition, field trips and social functions. Only on-site speakers will have the opportunity to present a paper. On-site participant will also be able to watch the recorded presentations “on demand” on the conference platform.
  • Online participants of the conference will be able to download the papers and presentations before the opening of the conference. They will be able to attend the presentations live in the scheduled sessions Central European Time time as well as viewing the recorded presentations “on demand” on the conference platform.


Papers and presentations will be in English. They will be published and downloadable from the ICSOBA website for the participants and ICSOBA corporate members. The papers will be indexed in platforms such as Google Scholar. The printed book of proceedings (TRAVAUX No. 53 will be sent as individual orders after the conference.


The latest technologies, equipment and other devices for the aluminium industry will be exhibited during the conference.

Exhibitors will be able to upload the brochure and video on the Conference Application – Whova – which enables connection with on-site and online participants.


You can contact Bijoy Satpathy: bijoy.satpathy@icsoba.org for any information concerning the exhibition.


Second Call for Papers

While keeping with the main fields of bauxite-alumina-aluminium, the conference will focus on the industry key challenges of today such as sustainability, decarbonisation, digitalisation, IA, …. whilst maintaining a high scientific and technical innovation nature focused on industrial application of scientific results to pilots and at plant level.

Technical Field Trips

Aluminium Dunkerque Smelter

Aluminium Dunkerque is pleased to offer you the opportunity to visit its primary aluminum production plant on October 31, 2024.


France's last major primary aluminum smelter, Aluminium Dunkerque specializes in the manufacture of slabs and ingots, in a wide variety of alloys, for high value-added applications in the automotive, transport and packaging sectors.


The foundry was built in France in the 1990s, right next to the Gravelines nuclear power plant, which supplies it with carbon-free energy.


The architect who designed the plant was inspired by the surrounding sand dunes and provided a tree-lined central patio, the starting point for the operational areas - and for your visit !


The tour will take you through the 3 production departments:

  • In the Carbon department, you'll pass through the automated anode storage area and get a glimpse of the baking furnace.
  • In the Reduction department, equipped with 264 AP30 pots powered at 400 kA, overhead travelling cranes can move from one hall to another thanks to a conveyor crane.
  • In the Casting shop, you'll see 3 vertical direct-casting machines and an ingot line, 7 furnaces supplying a capacity of 300 kt/year in rolling slabs and foundry ingots.

Weather permitting, the visit will be completed by a bus tour of the plant, to the deep-water port where raw materials are unloaded.


Already one of the world's leading producers of low-carbon aluminum, Aluminium Dunkerque is accelerating its energy and environmental transition with its ambitious decarbonization project called LowCAl : this Low Carbon Aluminium strategy, will also be presented.

Alteo Gardanne Alumina Refinery

Alteo offers a tour of its historic bauixte residue storage center, operating as a lagooning from 1900 to 1970, then as a dry-storage from 2006 until its rehabilitation in 2022.


The unique feature of this center, located 4 km from the alumina refinery, is its location between intial 2 valleys that were intically filled i to store these residues.


The eveolution of this site is amazing, particularly over  the last 5 years iwth the creation of rainfoll recovery pond and the profiling and composting of the storage compartement.


To complement the visit to the storage site, participants will also be given a brief overview of the refinery and its industrial transformation during a bus tour. Participants will be able to appreciate the scale and complexity of the refinery. It is also an opportunity to illustrate the company's commitment to environmental sustainability. In short, this bus tour offers participants a unique opportunity to immerse themselves in the history of alumina by discovering the plant - the cradle of the Bayer process - which has been located in Gardanne for 130 years.

ICSOBA 2024 President

Guillaume de Goÿs

Guillaume de Goÿs

CEO, Aluminium Dunkerque
Short Bio
More than 200 years ago, in the south of France, geologist Pierre Berthier discovered a mineral containing more than 50% aluminium oxide - later known as bauxite, after the French village where it was found: "Les Baux de Provence". In 1854, Henri Sainte-Claire Deville carried out the first industrial production of aluminium in Paris. In 1859, he published a work on aluminium in which he predicted its future use: "Aluminium will probably become an everyday metal". Since then, France is proud to be part of the industrial history of alumina and aluminium. Therefore, on behalf of Alteo , Aluminium Dunkerque , Rio Tinto and Trimet, as well as the entire "Aluminium France" association, I have the honor and the pleasure to welcome you to the 42nd edition of ICSOBA. We are convinced that sharing our work and our knowledge will contribute to finding better ways to produce the aluminium the world needs to become even more sustainable. I wish you a good and fruitful conference!
