About RemovAL

Bauxite Residue as a source for critical and other raw materials in Europe Bauxite Residue (BR) is produced as a red slurry (hence the common term " red mud ") from the Bayer process cycle. It is estimated that for each ton of alumina produced 0.9- 1.5 tons of solid residue is generated depending on the initial bauxite ore grade and alumina extraction efficiency.
