Mining and Refining Energy Efficiency World Aluminium

The bauxite refining process requires significantly higher energy, primarily in the form of heat and steam; natural gas, coal and oil are the main fuel sources and are combusted on site. The energy required by the Bayer Process is very much dependent on the quality of the raw material, with bhemitic or diasporic bauxites requiring higher temperature digestion, often associated with a higher fuel input.
