    Abstract : Tailings storage facilities (TSFs) serve as structures for storing tailings, i.e., waste materials generated by the mining industry. READ MORE

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

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

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

    Abstract : 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. 3. Evaluation of Dissolved Air Flotation for Water Purification: With Focus on Floc Characteristics and PFAS

    University essay from KTH/Kemiteknik

    Author : Ludwig Löf; [2021]
    Keywords : Water treatment; Sedimentation; Flotation; PFAS; Zeta potential; Vattenbehandling; Sedimentering; Flotation; PFAS; Zeta potential;

    Abstract : I detta projekt har experiment utförts med mål att förse kommunalförbundet Norrvatten med data som kan användas som underlag för beslutsfattande angående om deras fällningslinjer i vattenreningsprocessen ska köras i flotation eller sedimentering. För detta ändamål har koncentrationen av poly- och perfluorerade alkylsubstanser (PFAS) samt karaktär av agglomererade partiklar (flockar) undersökts och jämförts mellan fällningslinjer som körs i olika konfigurationer.

  5. 4. An Investigation of the breakage process of particles : With help of experimental results and discrete element methods

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

    Author : Ronni Bashiry; [2021]
    Keywords : Geotechnical Engineering; Breakage; Fracture; Spherical particles; DEM; Modelling; Numerical modelling;

    Abstract : In this study the breakage mechanics of brittle glass marbles was investigated. The pro-cess was to firstly investigate them in laboratory environment. The marbles or specimens was loaded until a crushing breakage occurred in a single point load test called Single Sphere Point load test in this document. READ MORE

  6. 5. Effect of Unit Operations on Food Particles – Evaluated by image analysis and correlated with mechanical tests

    University essay from Lunds universitet/Förpackningslogistik

    Author : Jan Roland Molina; Nuti Hutasingh; [2019]
    Keywords : Particle breakage; Mechanical test; Image analysis; Unit Operation; Bio-yield test; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : In order to successfully produce food products containing less damaged particles (approx. 1 cm3) it is important to investigate at which limit that the particle could be subjected to processing. This study attempted to predict particle breakage using mechanical test with image analysis as method validation. READ MORE
