Solidification of cryolite (Na3AlF6)-based bath takes place at different rates along the sideledge, and around alumina rafts and new anodes. The solidification rate has a significant impact on the structure and the chemical composition that determine

In aluminium electrolysis cells, the interface between molten metal and electrolyte is animated by surface waves. It is well known that there is a permanent deformation of the bath-metal interface (BMI) due to the magnetohydrodynamic force in the cel

The optimization of powder injection is a source of concern for several fields such as the agri-food industry, metallurgy, and ore extraction. Several physical mechanisms intervene during the injection of a granular material into a liquid: solid mech

The aluminum industry searches to improve the incorporation of the alumina into the electrolyte bath. This paper presents the development of a model to simulate the flow of alumina particles with the thermal exchange between the particles and the liq

The movement of waves on the surface of a fluid is always accompanied by a displacement of the fluid particles in the wave propagation direction, this is called the Stokes drift. This phenomenon can be found in aluminum electrolysis cells. More or le

Molten cryolite mixed with some additives is used as solvent of alumina by aluminium producers. Cryolite represents the dominating compounds in the wall protecting side-ledge and at the bottom part of the frozen crust on the top of the cells. As the

Recent investigations on aluminum electrolysis cell demonstrated limitations to the commonly used tier-3 slope methodology to estimate perfluorocarbon (PFC) emissions from high-voltage anode effects (HVAEs). These limitations are greater for smelters

Perfluorocarbons are important contributors to aluminum production greenhouse gas inventories. Tetrafluoromethane and hexafluoroethane are produced in the electrolysis process when a harmful event called anode effect occurs in the cell. This incident

Significant amounts of greenhouses gases are produced annually by aluminium smelters around the globe. Most of these emissions are carbon dioxide but perfluorocarbons are nonetheless an essential part of GHG inventories for aluminium smelters. The to
