  1. 1. Mineral Rights Legal Systems Governing Exploration and Exploitation

    Detta är en avhandling från Stockholm : KTH

    Författare :Eva Liedholm Johnson; KTH.; [2010]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineral Rights; mineral legislation; exploration permit; claim; exploitation- mining concession; lease; TECHNOLOGY Civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : The objective of this thesis is to examine the legal procedures and systems concerning granting or possessing mineral rights, and how such rights may be exercised, particularly given the diametric interests of land use, ownership and land tenure. The study, comparative in its nature, aims at highlighting the similarities and differences between the countries and states of comparison, and thereby identify interesting solutions of issues relating to the granting and exercising of mineral rights.

  3. 3. Computational methods and strategies for geometallurgy

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Pierre-Henri Koch; Luleå tekniska universitet.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometallurgy; process simulation; minerals; machine learning; textures; decision-making; Mineral Processing; Mineralteknik;

    Sammanfattning : At the interface of geology and mineral processing, geometallurgy is a powerful tool for enhancingresource efficiency. A spatial model that represents the ore body in terms ofmineralogyand physical properties is combined with a process model that describes the concentrationprocess. LÄS MER

  4. 4. Sampling from large flotation cells An invastigation of spatial distribution

    Detta är en avhandling från Luleå : Luleå University of Technology

    Författare :Lisa Malm; Luleå tekniska universitet.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flotation; sampling; Mineral Processing; Mineralteknik;

    Sammanfattning : The general trend in flotation technology today is towards larger flotation cells, which enables a higher throughput. However, adverse effects such as segregation and reduced froth transport efficiency have also been observed in larger cells. LÄS MER

  5. 5. Particle generation for geometallurgical process modeling

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Pierre-Henri Koch; Luleå tekniska universitet.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometallurgy; ore texture; texture classification; breakage simulation; process modeling; Mineralteknik; Mineral Processing;

    Sammanfattning : A geometallurgical model is the combination of a spatial model representing an ore deposit and a process model representing the comminution and concentration steps in beneficiation. The process model itself usually consists of several unit models. LÄS MER
