Bauxite residue, better known as red mud, is a waste product of the alumina industry, but with many unexploited values. The estimated inventory of bauxite residue in operating and closed alumina refineries reaches the value of several billion of tonnes.

Bauxite residue is a high volume byproduct of alumina manufacture which is commonly disposed of in purposebuilt bauxite residue disposal areas (BRDAs). Natural waters interacting with bauxite residue are characteristically highly alkaline, and have elevated concentrations of Na, Al, and other trace metals.
