3. Extraction of Metal Values : Thermodynamics of Electrolyte Solutions and Molten Salts Extraction Process
Abstract : Over the past centuries, a number of process routes for extraction of metal values from an ore or other resources have been developed. These can generally be classifiedinto pyrometallurgical, hydrometallurgical or electrometallurgical routes. READ MORE

4. Structure and function of microbial communities in acid sulfate soil and the terrestrial deep biosphere
Abstract : This thesis describes the use of different DNA sequencing technologies to investigate the structure and function of microbial communities in two extreme environments, boreal acid sulfate soil and the terrestrial deep biosphere.The first of the two investigated environments was soils containing un-oxidized metal sulfides that are termed ‘potential acid sulfate soil’ (PASS) materials.

5. Kraft lignin valorization by hydrotreatment over Mo-based sulfided catalysts
Abstract : The production of green fuels and chemicals from bio-based feedstock can suppress the dependency on fossil resources and help mitigate global climate challenges. Kraft lignin is a thermochemically modified natural lignin obtained from the pulping process as a byproduct. READ MORE
