1. 1. Investigating the potential of systematic optical petrography in a geometallurgical context : A case study on boulder characterization from Rajapalot property, Finland

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Annie Björk; [2023]
   Keywords : Petrography; optical microscopy; scanning electron microscopy; geometallurgy; mining value chain; Peräpohja belt;

   Abstract : Geometallurgy describes a holistic approach to mining (integrating geological, metallurgical, geotechnical, environmental, and more parameters) with the goal to improve the efficiency and sustainability of a mining operation. The potential of systematic optical petrography in a geometallurgical context was investigated in this study, as well as how petrography may be useful across disciplines in several blocks of the mining value chain.

3. 2. Life Cycle Assessment of Food Sensors

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Weijie Yan; [2023]
   Keywords : ;

   Abstract : The global demand for food increased with the booming trend of population, while food waste is a severe issue to be solved. Xanthine is a chemical compound which will accumulate in meat after the death of the animal, and the concentration of it can be an indicator of meat freshness. READ MORE

4. 3. Making Artisanal Gold Miners ‘Investable’ - A Novel Means of ‘Improving’ Artisanal and Small-Scale Mining? A neoliberal eco-governmentality analysis of ‘responsible’ artisanal and small-scale gold mining: the case of the Lake Victoria Gold Programme in Migori County, Kenya

   University essay from Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi; Lunds universitet/LUMID International Master programme in applied International Development and Management

   Author : Gustav Dahlqvist; [2023]
   Keywords : Artisanal and Small-Scale Mining ASM ; responsible mining initiatives; neoliberal eco-governmentality; investability; gold; Kenya; Social Sciences;

   Abstract : Objectives: Artisanal and Small-Scale Mining (ASM) - a labour-intensive and low-tech mode of minerals extraction and processing - has received increasing attention amidst global commodity booms and its concurrent expansion. Infamously associated with negative social and environmental impacts, responsible mining initiatives have emerged to promote, measure, and enforce sustainable mining practices for ASM. READ MORE

5. 4. Character and Evolution of Ore Mineralisation in the Te-Rich Enåsen Au-Cu Deposit, Central Sweden

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Simon Pieslinger; [2023]
   Keywords : ore geology; partial melting; quenching textures; symplectite; tellurides; critical metals;

   Abstract : The Enåsen gold deposit is located in Gävleborg county in central Sweden. Mining operations at Enåsen took place from 1984 to 1991 with Au as the main target for exploitation. The deposit has been interpreted as a metamorphosed Palaeoproterozoic analogue to near-recent epithermal Au mineralisations of a high sulphidation type. READ MORE
