Toward the bioleaching of bauxite residue by Gluconobacter oxydans
Abstract Aim This project evaluated a biologically mediated strategy to solubilize several rare earth elements and critical raw materials, including scandium, from bauxite residue. This work seeks to expand on previous research on contact leaching with bauxite.

Rare earth elements in karst-bauxites: a novel untapped European resource? [PDF]
Karst-bauxite deposits form as a result of the accumulation of residual clay minerals in depressions on a karst limestone surface, and their subsequent lateritic weathering.

Available alumina and active silicon in gibbsite bauxite are important indicators for the quality of bauxite. These two components are commonly determined by Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES).

Coal fly ash (CFA) is an abundant industrial waste rich in silica and alumina and represents a viable feedstock for zeolite synthesis; however, high levels of calcium and iron limit zeolite purity and crystallisation. This study evaluates acid refluxing and acid roasting as pre‐treatment strategies for the simultaneous removal of Ca and Fe from high ...

Abstract The paleomagnetism of Miocene calc‐alkaline volcanics and sediments from Sardinia has firmly showed that the Corsica‐Sardinia microplate rotated 50°–60° counterclockwise (CCW) with respect to Europe between 21 and 15 Ma, during its drift from the Provencal margin. However, Permian to Eocene rocks from central‐south Sardinia revealed higher (up

A framework for capturing indirect impacts in site‐level screening for biodiversity risks
Abstract Site‐based industrial operations such as mining, oil and gas extraction and renewable energy development are associated with many direct and indirect impacts on biodiversity. Consideration of the full range of these impacts when selecting a buffer distance to approximate the Area of Influence (AoI) of a project is critical for effective ...

Combined Decarbonizing Technologies for Treatment of Bauxite Residues
This study explores both pyrometallurgical and hydrometallurgical methods for decarbonizing and recovering valuable metals from bauxite residue, with hydrogen plasma reduction and direct acid leaching as the primary approaches.
