This article presents an extensive review of scientific publications focused on how the impacts bauxite mining and refining have been investigated. includes results which types addressed in details concerning social years 2010‒2020. The analysis reveals that while environmental are most prominent academic publications, increasingly investigated recent years. Between 2011 2020, there 14 covering...

In a context of overexploitation natural resources, circular economy and particularly the extraction resources from secondary sources are essential to sustain number key technologies including renewable energies. Among sources, bauxite residue contains critical elements rare earth (REEs) (712 mg/kg). We investigated use soft selective dissolution protocols at mild pH values (2–6) as an alternat...

The low-grade bauxite in southern Shanxi Province, China is enriched multiple critical metal elements, including Li, Ga, V, Se, and rare earth elements (REEs), which have reached the standard of comprehensive utilization as independent deposits or associated resources. Even more importantly, identifying modes occurrence these essential for designing technologies to extract metals from ores. Thi...

The foreseen decarbonisation of the cement industry by 2050 will require a combination different measures in current manufacturing practices such as improvement energy efficiency, use alternative fuels, reduction clinker to ratio, and integration carbon capture, especially beyond year 2030. production binders, for substitution product families cement, is under investigation due its significant ...

Weathering is a complex process comprising physical disaggregation, chemical and biological decomposition of rocks and minerals transforming complex structure minerals in simpler ones. Hydrolysis of silicates is perhaps the most important process but associated certainly to biological weathering. It is discussed the role ofwaters: activities/concentrations of chemical species, pH, Eh, importanc...
