    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Leo Barbosa; [2021]
    Nyckelord :Gold characterization; gold as by-product; Lappberget ore; Garpenberg Mine;

    Sammanfattning : Ore characterization studies are of great importance to the mining industry, especially when dealing with precious metals by-products. It is a way towards increasing mining efficiency. LÄS MER

  3. 12. A Geometallurgical Approach Towards the Correlation Between Rock Type Mineralogy and Grindability: A case study in Aitik mine, Sweden

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Raoul Schmitt; [2021]
    Nyckelord :Geometallurgy; autogenous grinding; process mineralogy; grindability test; abrasion breakage; automated mineralogy;

    Sammanfattning : Aitik is a large copper porphyry type deposit located in northern Sweden, currently exploited at an annual rate of approximately 45Mt. The ore's exceptionally low head grade of 0.22 % Cu and varying degrees of hardness across the entire deposit pose challenges to the two fully autogenous grinding lines, each of which comprises a 22.

  4. 13. A study of wear and load behaviour on bucket teeth for heavy-duty cable shovels

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Jamal Choudhry; [2020]
    Nyckelord :DEM; FEM; bucket; teeth; cable shovel; wear; Archard s law; LS-DYNA; scan;

    Sammanfattning : Many of today’s engineering advancements rely on minerals such as copper, gold and iron. For this reason, the mining industry plays an important role for the development of society and technological wonders. Mining excavators are commonly used tools for extracting the minerals from the mine. LÄS MER

  5. 14. Undermining the Local: Power, Acceptance, and Confidence surrounding a Chilean Mining Operation : Social Impacts of the Mining Operation Los Pelambres on the Cuncumén Community

    Master-uppsats, Uppsala universitet/Naturresurser och hållbar utveckling

    Författare :Julia Schwab; [2020]
    Nyckelord :Sustainable Development; Ethnography; Social License to Operate; Mining; Power; Trust; Victim Mentality;

    Sammanfattning : The present ethnographic research explores the socio-economic repercussions of a copper mining operation in Chile on its host community. By examining the development of the relationship between this local community and the mining company since the latter’s arrival, this thesis sheds light on the possible (secondary) impacts of corporate social responsibility (CSR) measures and participatory spaces on intracommunal dynamics.

  7. 15. Geochemical and Mineralogical Comparison of XRT-XRF Scanning Technology Versus Traditional Analysis of Drill Core from the Assarel Porphyry Copper-Gold Deposit (Panagyurishte District, Bulgaria)

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Diego Delgado Yanez; [2020]
    Nyckelord :Assarel porphyry copper; GeoCore X10; Sustainable mining; XRT XRF; mineral characterization; geochemical characterization; X-MINE Project;

    Sammanfattning : Ongoing, environmental and economic matters related to mining sustainability and its impacts are leading to the search for new ways to asses and extract commodities more efficiently. A key aspect in the shift to more sustainable mining is the rapid, digital characterization of orebody mineralogy and geochemistry to help optimize the extractive process. LÄS MER
