Red mud - Wikipedia

Red mud, also known as bauxite residue, is an industrial waste generated during the refinement of bauxite into alumina using the Bayer process.It is composed of various oxide compounds, including the iron oxides which give its red color. Over 95% of the alumina produced globally is through the Bayer process; for every tonne of alumina produced, approximately 1 to 1.5 tonnes of red mud are also ...

Investigating the Properties of ed Mixture Lightweight ...

To make better use of large amounts of discarded bauxite tailings (BTs), a ed mixture lightweight soil mixed with BTs as filler (FMLSB) was proposed. Using the orthogonal experimental design method, the effects of various contents of cement, BTs, and on the fluidity, wet density, unconfined compressive strength, water absorption, and microstructure of FMLSB were studied.

Bauxite - ALS

Drilling and sampling of bauxite deposits As bauxite deposits are usually extensive, relatively thin (most average <10m thick) and close to the surface, drilling is usually a series of shallow vertical holes set out on a regular grid. It would be rare for drill holes to exceed 50m depth with drilling at most deposits being much shallower than this.
