AlCircle: What is IB2’s breakthrough technology for low grade bauxite refining?
Romain Girbal: Curbed by environmental and financial constraints involved by the exploitation of low-grade bauxite, refineries have so far preferred to import bauxite.
IB2 technology was developed to optimize the use of low-quality bauxite and allow to produce the same amount of alumina with less bauxite, less sodium hydroxide and less wastes providing financial, environmental, strategic and technological benefits.
IB2 stands for the combination of Improved Bauxite and Improved Bayer. This combined approach allows alumina refineries to achieve great results and this is where IB2 is a real game changer for them: while securing their supply, refineries will adopt a profitable and environment friendly solution.
