In the extraction of aluminium Process X : applied for red bauxite to remove iron oxide (chief impurity) Process Y : (Serpeck's process) : applied for white bauxite to remove Z (chief impurity) then, process X and impurity Z are : (1) X=Hall and Heroult’s process and Y=SiO2X = \text{Hall and Heroult's process and } Y = \text{SiO}_2 (2) X=Baeyer’s process and Y=SiO2X = \text{Baeyer's process and } Y = \text{SiO}_2 (3) X=Serpeck’s process and Y=iron oxideX = \text{Serpeck's process and } Y = \text{iron oxide} (4) X=Baeyer’s process and Y=iron oxideX = \text{Baeyer's process and } Y = \text{iron oxide}
