  2. 1. 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

  5. 3. Influence of alumina on the zinc slag fuming processes : an experimental study on physical properties and leaching behaviour of the generated fayalite-type slag

    Author : Sina Mostaghel; Heikki Kusti Jaikanen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Physical properties; Thermodynamic calculations; environmental properties; Sustainable extraction; Zinc fuming; Copper; Process Metallurgy; Processmetallurgi;

    Abstract : Recycling of secondary raw materials by non-ferrous metal producers is steadily increasing. These materials inevitably introduce various impurities to the production furnaces, which can change the chemical composition, and thereafter, the physical and chemical properties of the products and by-products of the operation.

  7. 5. Leaching of water-granulated iron silicate slags and their compounds : A study of synthetic and industrial slag systems

    Author : Jakob Kero Andertun; Fredrik Engström; Caisa Samuelsson; Pasi Peltola; Bart Blanpain; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : Copper smelter slag is a residue product of the pyrometallurgical extraction of copper. Due to its physical properties, the iron silicate type of copper smelter slag has many possible application areas, e.g., different aggregates and abrasives. READ MORE
