Bauxite Refining Subegory Of The Aluminum Segment Of . Summary . As described in the foregoing paragraphs, there is fundamentally only one process for refining bauxite, the Bayer process. The combination process, a variation of the .Bayer process, retreats the red mud waste from the Bayer process to recover additional aluminum and alkali values.
If Guinea can encourage the use of hydropower for its bauxite refineries, the refining process will not only be greener, but the project could electrify the country's rural areas (where only around six percent of households currently have electricity), and give mining companies a reliable fuel source without having to import coal and petroleum, as they do today.
