  1. 1. Investigating the effect of grinding method on ore beneficiation behaviour

    University essay from Luleå tekniska universitet/Mineralteknik och metallurgi

    Author : Mellisa Tanaka Mundida; [2023]
    Keywords : flotation; grinding; liberation; chalcopyrite; beneficiation; grinding method; selectivity index; VRM; Aitik ore; rodmill; particle shape;

    Abstract : Commodity projection studies anticipate an exponential increase in copper demand and decreasein mill grade of deposits currently exploited globally. Most of this demand is driven by theindispensable use of copper in electrification and currently, the growing demand in the contextof the green transition. READ MORE

  3. 2. Evaluation of Wet Spinning of Fungal and Shellfish Chitosan for Medical Applications

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Ghasem Mohammadkhani; [2021]
    Keywords : Chitosan fiber; Fungal fiber; Wet spinning; Hydrogel; Suture applications;

    Abstract : The aim of this project was to address the food waste problem, particularly bread waste, to some extent by producing monofilaments obtained from wet spinning of fungal hydrogel through the cultivation of Rhizopus delemar on bread waste. The project had two phases. READ MORE

  4. 3. Material Transfer Mechanisms during Interaction of Aluminium Alloy and Tool Steel at Elevated Temperatures

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Gabriel Macêdo; [2020]
    Keywords : material transfer mechanisms; high temperature tribology; hot metal forming tribology; hot-stamping of aluminium alloys; aluminium alloys;

    Abstract : Hot stamping of aluminium alloys allows for increased formability, decreased springback and the possibility of integrating age-hardening heat treatments into the process. However, it can be challenging due to the occurrence of material transfer of aluminium onto the tool, as aluminium is prone to adhesion even at low temperatures. READ MORE

  5. 4. Mechanical dry grinding process of saw chain

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Dennis Svensson; Tobias Falk Svärd; [2019]
    Keywords : dry grinding; abrasive; grinding wheel; grinding disc; grinding wheel; friction; energy; work; chainsaw; saw chain; cutting link; cutting edge;

    Abstract : The cutting links on chainsaws needs to be sharpened regularly to retain its sharpness. The most effective way is to use a machine wheel grinder. However, due to high friction there is a high risk of tempering the steel and damaging the sustainability to wear, resulting in a dull cutting edge. READ MORE

  6. 5. Wear testing of high-alloy carbon steel used in mining tools

    University essay from KTH/Materialvetenskap

    Author : Sara Olsson; Linn Efsing; [2013]
    Keywords : Wear; Wear-testing methods; Adhesive wear; Abrasive wear; Nötning; Nötningstester; Adhesiv nötning; Abrasiv nötning;

    Abstract : Wear is a commonly occurring degradation mechanism for materials and components in the rock drilling industry. The wear can occur by either abrasion or adhesive wear. Further corrosion and presence of water or other lubricating fluids with or without particles may influence the behavior. READ MORE
