three tonnes of bauxite are required to produce one tonne of alumina. 90% of the global alumina supply of around 90 million tonnes is used in aluminium production. DEFINITION The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide). The aluminium oxide must be purified before it can be refined to aluminium metal. Important Ore: BAUXITE. CONTENTS: Al2O3 - 30 -54% Rest -Silica‚ Iron Oxides and Titanium Oxides.

and larger and greater specifications are desired. The initial step of metallurgy should be to create aluminium oxide. In alumina oxide production with sintering process‚ we need to first create the raw materials compounded by bauxite‚ limestone and alkali into clinker. The sintering process is completed within the vertical roller mill whose inner temperature is 1300℃. The final phase of aluminium oxide manufacturing is to roast aluminum hydroxide into alumina oxide. The inner temperature is about
