Bauxite residue tonnage was then estimated by applying an overall ratio of 1.5 to the alumina production Hamada 1986 . Factors such as bauxite grade alumina extraction efficiency and caustic losses will vary between refinery operations so a world average ratio value of 1.5 should only be regarded as approximate. 2.2.
