  1. 1. Development of a geometallurgical testing framework for ore grinding and liberation properties

    University dissertation from Luleå University of Technology : Luleå University of Technology

    Author : Abdul-Rahaman Mwanga; Luleå tekniska universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grindability test; mineral texture; breakage properties; mineral liberation; process modeling; geometallurgy; Mineral Processing; Mineralteknik;

    Abstract : Efficient measurement methods for comminution properties are an important prerequisite for testing the variability of an ore deposit within the geometallurgical context. This involves the investigation of effects of mineralogy and mineral texture on the breakage of mineral particles. READ MORE

  2. 2. Alkylglucosides - physical chemical properties

    University dissertation from Luleå University of Technology : Luleå University of Technology

    Author : Frederik Nilsson; Lunds universitet.; Lund University.; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; penetration experiment; DSC; SAXS; NMR self-diffusion; phase separation; size micro-structure; aggregate-aggregate interaction; liquid crystalline phases; micelles; alkylglucosides; phase diagrams; fluorescence.; Physical chemistry; Fysikalisk kemi;

    Abstract : The aim of this study is to characterise the physical-chemical properties of alkylglucosides. Alkylglucosides are non-ionic surfactants synthesized from glucose and a fatty alcohol. The glucose molecule constitutes the hydrophilic head group and the fatty alcohol constitutes the hydrophobic tail. READ MORE

  3. 3. Mircostructure and rheological properties of concentrated tomato suspensions during processing

    University dissertation from Luleå University of Technology : Luleå University of Technology

    Author : Elena Bayod; Lunds universitet.; Lund University.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheology; microstructure; morphology; flocs; tomato paste; ketchup; fibre suspensions; viscoelastic properties; particle size distribution; time dependency; network; yield stress; wall slip; Mooney; Cox-Merz rule; Tikhonov; tube viscometer; rotational viscometer; homogenisation; shearing;

    Abstract : Food processing comprises operations such as dilution (changing the concentration), homogenisation (changing the particle size), and subsequent pumping (shearing), among others. It is thus of great interest to gain a better understanding of the mechanisms governing the creation and disruption of structures during these engineering operations, and the way in which they are related to the textural and rheological properties of the material.

  4. 4. Interaction between pellet properties and blast furnace operation

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Ulrika Leimalm; Luleå tekniska universitet.; [2010]
    Keywords : Process Metallurgy; Processmetallurgi;

    Abstract : The raw material properties of iron-bearing material and coke have a significant impact on the blast furnace (BF) process. The raw materials are designed and chosen to achieve smooth BF operation but the operational parameters can be simultaneously modified to meet properties of selected raw materials. As the pre-set process conditions change, e. READ MORE

  5. 5. Development of a geometallurgical framework for iron ores - A mineralogical approach to particle-based modeling

    University dissertation from Luleå University of Technology

    Author : Mehdi Parian; Luleå tekniska universitet.; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometallurgy; process simulation; breakage characterization; ore texture; iron ore; modal mineralogy;

    Abstract : The demands for efficient utilization of ore bodies and proper risk management in the mining industry have resulted in a new cross-disciplinary subject called geometallurgy. Geometallurgy connects geological, mineral processing and subsequent downstream processing information together to provide a comprehensive model to be used in production planning and management.
