  1. 21. Anaerobic Co-Digestion Of Food Waste And Kraft Pulp Fibre To Enhance Digestate Dewaterability

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Kwame Boateng Agyemang; [2021]
    Keywords : Anaerobic digestion; Digestate; Dewaterability; Food waste; Pulp fibre;

    Abstract : Digestate produced during anaerobic digestion of food waste is recognised as a good alternative to mineral fertilizer which could also be used to amend soil properties. This has conventionally been applied directly and unprocessed to nearby farms or processed and transported elsewhere. READ MORE

  3. 22. Online Metallurgical Mass Balance and Reconciliation

    University essay from Umeå universitet/Institutionen för fysik

    Author : Emil Andersson; [2021]
    Keywords : dynamic; froth flotation; mass balancing; mineral processing; reconciliation;

    Abstract : In mineral processing, one of the most important and versatile separation methods is flotation. Flotation utilizes the different surface properties of the valuable minerals in the ore to separate them from the less valuable gangue material in the ore. Crushed and ground ore is mixed with water and fed into flotation tanks. READ MORE

  4. 23. Exploring Managerial Challenges Emerging from Procurement of Mineral Concentrates : Case study on Boliden

    University essay from KTH/Skolan för industriell teknik och management (ITM)
