Turin – September 20th, 2019 2 Aluminium use cases: Rio Tinto & AP

Bauxite Alumina Aluminium 3 steps from the mine to the metal: • : 4 bauxite mines • alumina: 3 alumina plants • aluminium: 19 smelters in 6 countries

• The Aluminium Dunkerque plant (North of ) is an aluminium smelter of 250 ktpy aluminium capacity [the highest-producing primary aluminium plant in the EU-28].

Turin – September 20th, 2019 Aluminium production process

• MONSOON contribution: – Carbon area: • Predictive Maintenance • Anode quality prediction – Electrolysis area: • Bath and metal height prediction Electrolysis pot (with courtesy of AP) • Thermal balance prediction Si possible avec anodes

415 kg C/t Al

Turin – September 20th, 2019 5 Focus on Anode Quality predictive function

• predict non conformant production and trigger relevant actions to correct the problem (optimization)

Anode non-quality can lead to non-homogeneous and reactive anodes Reduced lifecycle on pots (more frequent anode change) Incidents on pots

CO2 over emissions due to the anode overconsumption

Turin – September 20th, 2019 6 Anode Quality

To provide a support to paste plant workers to improve anode density = quality

With a predictive function which:

• Detects on real time the periods (30 minutes) of improvable quality = classification

• Identifies the main variables that caused the lower quality period

• Gives recommendations to optimize the process to improve anode quality = optimization
