Extraction and recovery of valuable elements from Red Mud through biohydrometallurgy
Among all the materials, aluminum played a key role in the industrial development of the last two centuries, thanks to the breakthrough of the Bayer process. This consists in alumina extraction from bauxite by chemical dissolution. The main waste produced through the Bayer process is called Red Mud …

An investigation into the effect of solid particulate phase on the bioleaching performance of Sulfolobus metallicus
… used in the high intensity tank-based commercial biohydrometallurgy processes are mainly mesophiles, although moderate thermophiles are currently used at Youanmi Mine in Australia (Brierley, 1997). Extreme thermophiles have been found to exhibit enhanced oxidation kinetics in terms of rate of …

Bio-engineered gas diffusion electrodes (GDEs) for proton exchange membrane fuel cells (PEMFCs)
… thesis aims to evaluate the incorporation of biohydrometallurgy in producing Gas Diffusion Electrodes (GDEs) for PEM Fuel cell applications. The biomineralisation and subsequent catalytic activity of spin coated engineered biofilms is investigated, as is the use of planktonic cell generated …

Electrochemical speciation and quantitative chromatography for modelling of indium bioleaching solutions
In order to meet increasing indium demands, (bio)hydrometallurgical winning of low-grade sources will likely be required. The goal of this work in the scope of the Biohydrometallurgical Centre Freiberg, was to use geochemical modelling to improve indium leaching and extraction efficiency. Indium …

Developing quantitative approaches to determine microbial colonisation and activity in mineral bioleaching and characterisation of acid rock drainage
… mineral sulfide ores of varying grades through biohydrometallurgy. It also influences acid formation and mineral deportment from sulfidic waste rock generated in mining processes and is key to its comprehensive waste rock characterisation for acid forming potential. This study assesses mixed …
