Enhanced Aluminium Extraction from Gibbsitic Bauxite by Electroreduction in the Bayer Process
MetalsThe Bayer process is used to extract alumina from bauxite, resulting in the formation of a highly alkaline solid residue known as bauxite residue (BR). However, such residue contains insufficient iron (

Preliminary Characterization of Three Metallurgical Bauxite Residue Samples
Materials Proceedings, 2021 Bauxite Metallurgical Residue (BR) is a highly alkaline and very fine-grained by-product of the Bayer process for alumina production. Its huge global annual production has resulted in increasing accumulation of BR, causing deposition problems and serious

Natural Resources and Political Patronage in Africa: An Ethnicity Level Analysis
Review of Development Economics, EarlyView.ABSTRACT We investigate the effect of resource discoveries on ethnicity‐level political patronage in Africa using a large geospatial dataset of 254 ethnic groups in 15 countries over the period 1960–2004. We find that the first (or single first) resource discovery in a virgin ethnic homeland increases the share of cabinet posts of that ethnicity.

High Temperature Treatment of Selected Iron Rich Bauxite Ores to Produce Calcium Aluminate Slags
Materials Proceedings, 2021 The Pedersen process is a method to produce alumina from Al-containing sources, and it is a more material-efficient method than the current commercial Bayer process, since the formation of bauxite residue (red mud) is avoided, and the bauxite can be ...
