Bauxite deposits are spread worldwide, mostly occurring in tropical or subtropical regions. Although proven reserves of bauxite are expected to last for many years, the quality of the reserves that can be economically accessed is declining. For refiners, who are in the business of processing bauxite to make alumina, and eventually aluminum metal, this is a challenge with both financial and ...

Bauxite residue (BR) is a hazardous industrial waste and also becomes an important reserve of rare earth elements (REE). An elegant process for achieving separation of REEs against silica from an ironremoved BR was established in this paper through selective leaching of silica with simultaneous enrichment of REEs.
Since bauxite is a naturally occurring mineral, it has a number of impurities, like iron, silica, Titania, calcium, and small quantities of phosphorous, sulfur, zinc, magnesium and various carbonate and silicate minerals. These impurities not only create quality problems, but also increase production costs, besides causing environmental pollution.
