Bauxite residue is the waste solid produced from alumina extraction process (Power et al. 2011).To date, the inventory of bauxite residues reached over 5.0 billion tons with an increasing rate by 200 million tons per year (Xue et al. 2019).The stored bauxite residues not only occupy large areas of the landscape, but also threaten surrounding …

At the processing plant, the bauxite is heated hot enough to melt the rock. Electricity is applied to the melted rock to separate out pure aluminum in its liquid state. The leftover material, called slag, is broken up, forming large amounts of what is basically burnt rock, which is caustic and reactive.

To process the bauxite, the bauxite must be mined, crushed, and delivered to the refinery. ... screen separates the fine bauxite from the coarse intrusions and the trommel underflow is then pumped to the downstream process plant. The intrusions are rejected as trommel overflow and conveyed to a waste dump. Fig. 3.6. Flow sheet of drum scrubber ...

This review is limited to …

Aluminum processing - Ores, Refining, Alloying: Aluminum is the third most abundant element on Earth's surface. Only oxygen and silicon are more common. Earth's crust to a depth of 16 km (10 miles) contains 8 percent aluminum. Aluminum has a strong tendency to combine with other common elements and so rarely occurs in nature in the metallic form.
