  1. 11. Comparison of Level Control Strategies for a Flotation Series in the Mining Industry

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Frida Norlund; [2022]
    Keywords : Technology and Engineering;

    Abstract : Separating valuable minerals from waste rock is an important step in the production of metals. This is for copper ore done through a process called flotation. A flotation series consists of tank cells in series where the minerals are collected in a froth on top of the cells. READ MORE

  3. 12. Evaluation of long-term effects of excavated sulfide-bearing rock : - A case study in western Sweden

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

    Author : Ida Sundblom; [2022]
    Keywords : sulfide-bearing rock; acid rock drainage; sulfide oxidation;

    Abstract : Sulfide-bearing rock that is excavated in conjunction with construction projects can cause environmental and construction engineering problems. Sulfidic minerals oxidize when they are exposed to an oxidant and water, which can make them generate acid rock drainage (ARD) with high concentrations of metals and sulphate. READ MORE

  4. 13. Development of grout for deep shaft

    University essay from KTH/Byggteknik och design

    Author : Karl Lindberg; Adam von Krusenstierna; [2021]
    Keywords : Rock injection; Grout; Shaft; Laboration; Cement; Cement mixture; Bergsinjektering; Injekteringsbruk; Schakt; Laboration; Cement; Cementblandning;

    Abstract : In tunnel engineering one of the most important factors are the groundwater flow. To solve this problem a method called grouting is commonly used. In this study grout mixes are developed based on specific requirements for a deep shaft located next to a body of water. READ MORE

  6. 15. 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
