  2. 1. Recycling of Blast Furnace Sludge within the Integrated Steel Plant : Potential for Complete Recycling and Influence on Operation

    Author : Anton Andersson; Lena Sundqvist Ökvist; Hesham Ahmed; Caisa Samuelsson; Yongxiang Yang; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : Ore-based steelmaking generates various residues including dust, sludges, scales and slags. Internal and external recycling has allowed for 68-90 % of the dust, sludges and scales to be recycled. However, several residues are landfilled despite containing elements valuable as raw material in the production of steel. READ MORE

  4. 2. Settling Mechanisms of Valuable Metal Droplets in Iron Silicate Slag

    Author : Jenny Isaksson; Caisa Samuelsson; Andreas Lennartsson; Anton Andersson; Ari Jokilaakso; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : A significant source of copper losses from pyrometallurgical copper extraction is attributed to dissolved and entrained copper in discarded slag. Entrained copper can be recovered via pyrometallurgical slag cleaning in a settling furnace where the droplets settle under gravity. READ MORE

  5. 3. Slag Cleaning of a Reduced Iron Silicate Slag by Settling : Influence of Process Parameters and Slag Modification on Copper Content

    Author : Jenny Isaksson; Caisa Samuelsson; Andreas Lennartsson; Anton Andersson; Pekka Taskinen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Copper losses; matte; speiss; fayalite slag; temperature; settling time; solid phases; industrial trial; CaO modification; Process Metallurgy; Processmetallurgi;

    Abstract : During the pyrometallurgical extraction of copper, a significant part of the copper is lost with discard slag, which decreases profits, overall copper recovery, and efficiency of raw material usage. Smelting furnace slag usually has a copper content that is close to or higher than that of copper ores. READ MORE

  6. 4. Dispersion Coating for Active Food Packaging: Aroma Interactions and Oxygen Scavenging

    Author : Anna Nestorson; Lars Järnström; Anders Leufvén; Caisa Andersson; José M. Lagaron; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active food packaging; Dispersion coating; Latex; Aroma compounds; Oxygen scavenging; Chemical engineering; Kemiteknik; Chemical Engineering; Kemiteknik;

    Abstract : ABSTRACTActive packaging materials prolong the shelf life or preserve the quality of packed food by absorbing oxygen, ethylene, moisture or odours, or by releasing antimicrobial agents, antioxidants or flavours. In dispersion coating, a latex is applied onto paper or paperboard to form a barrier film against water, water vapour, oil or gases. READ MORE
