1. Introduction The Bayer process of extraction of alumina from bauxite remains the most economical process till date. In the Bayer process, the insoluble product generated after bauxite digestion with sodium hydroxide at elevated temperature and pressure to produce alumina is known as "red mud" or "bauxite residue" which is highly alkaline in nature with a pH of 10.5-12.5.

Disclosed herein, is a process for recovering- valuable metals and/or their oxides from red mud bauxite residues or similar. The process comprises: calcining a red mud residue having a pH of less than about 10 to provide a calcinated red mud residue; acid leaching the calcinated red mud residue to provide a silica rich solid component and an acid leachate; separating the silica rich solid ...

A factorial design and response surface approach has been employed to optimize the neutralization, partial reduction, magnetization and carbonization of highly alkaline Red Mud bauxite residues as derived from the Bayer process using highly acidic pyrolysis bio-oil as the limiting reagent. The impact of the factors temperature, reaction time and – most importantly – the minimum bio-oil/Red ...

Red mud is produced in huge amounts as a waste product in the production of aluminium from bauxite by the Bayer's method. It may be used as a raw material in tile production or in the heavy clay industry. Also it can be used for cesium adsorption from the contaminated agricultural …

Red Mud is produced during the process for alumina production. Depending on the raw material processed, 1–2.5 tons of red mud is generated per ton of alumina produced [1]. In India, about 4.71 million tons/annum of red mud is produced which is 6.25% of world's total digestion with sodium hydroxide at elevated temperature and pressure [2].
