网页2019年1月20日Bauxite residue (red mud) is the by-product generated during the extraction of alumina from bauxite ore using the Bayer Process (Kirwan et al. 2013), and is currently being produced at a global rate of 150 Mt per annum, adding to the 3 Bt already in storage worldwide (Evans, 2016).

Re‐using bauxite residues: benefits beyond (critical raw)
网页2018年5月7日Bauxite residues (also known as ‘red mud’, ‘Bayer process tailings’ or ‘bauxite process tailings’) are generated from alumina production where bauxite is digested in hot NaOH solution via the Bayer process. 22 The production of 1 tonne of alumina generates between 1 and 1.5 tonnes of bauxite residue. 23 Currently, the yearly global

Bauxite Properties, Formation, Uses ? geologyscience
网页2023年4月3日References Bauxite is a sedimentary rock mineral that is the primary source of aluminum. It is formed through the weathering of aluminum-rich rocks in tropical and subtropical regions. The name bauxite is derived from the French village of Les Baux, where it was first discovered in 1821 by geologist Pierre Berthier.
