Latest Patents

Jon G Lindkvist holds a patent for a method titled "Method for treatment of potlining residue from primary aluminium smelters." This innovative method addresses the treatment of spent potlining from aluminium reduction cells, which includes the refractory material. The process involves crushing the spent potlining and supplying it to a closed electrothermic smelting furnace, where it is melted at temperatures between 1300°C and 1750°C. An oxidation agent is introduced to oxidize carbon and other oxidizable components, while a source of calcium oxide is added to react with fluoride, forming a calcium aluminate or calcium aluminate silicate slag.
