“…The red mud can be stored in impoundments but its reuse after adequate treatments for different purposes has been studied in several countries. The storage solution is economically problematic due to the costs of the realization and maintenance of containment structures and implies environmental problems for the storage site (huge areas), most of all due to the mud caustic nature that could pose a risk for all living organisms [4]. There are several works on red mud reuse, for example, as acidic amender or bottom sealant in disposal sites construction, as catalyst in hydrodechlorination of tetrachloroethylene , for iron and titanium oxides extraction, for the production of ceramic glazes.…”

The objective of this study was to investigate the removal of phenol from aqueous solution by using activated and non-activated red mud in adsorption experiments. The study was carried out as function of red mud dosage and initial phenol concentration. It was found that the maximum removal was obtained at dosage of 0.5 g of red mud and initial concentration of phenol 40 mg/l. Activation has no positive effect on adsorption effectiveness.

“…Red mud, is the major solid waste produced during alkaline leaching of bauxite in the Bayer processes. For every tone of alumina produced, roughly 1-2 tonesof red mud residue are generated [1][2][3]. The increasing demand of alumina generates more red mud which is disposed on large areas.…”

Today the red mud generated from alumina production is a resource, a material that can be valorized, an opportunity. The current practice in waste management in some parts of the planet has to be revised. We need to change technologies and become more aware and thoughtful on our footprint on Earth. Red mud is the main waste generated from the bauxite Bayer process. Having a complex composition with predominantly Al2O3 (14-27%), Fe2O3 (19-56%) contents, viable solutions were sought for the reuse of the red mud. A number of applications have resulted in the recovery of metallic components, chemical industry, and building materials industry. A field of red mud applicability, which has enabled the development of innovative and sustainable techniques, is that of the environment. The paper presents the results of the researches carried out in order to valorize the red mud in the treatment of two categories of wastewater: phosphates waters and mine waters. The influence of the experimental parameters on the pollutant removal efficiencies in these wastewaters is highlighted.
