2. 1. Development of a process model for a Peirce-Smith converter

   Author : Andreas Lennartsson; Eetu-Pekka Heikkinen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Abstract : Copper was one of the first metals ever extracted and used by mankind. It is used for its unique properties, like corrosion resistance, good workability, high thermal conductivity and attractive appearance. New mines are opened to maintain a supply of primary feedstock to copper smelters. READ MORE

4. 2. Transcriptional control of Bactericidal/permeability increasing protein (BPI) and cathepsin G in myeloid cells

   Author : Andreas Lennartsson; Avdelningen för hematologi och transfusionsmedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; extracellular fluids; Haematology; extracellulära vätskor; Hematologi;

   Abstract : The neutrophil store its effector proteins in several distinct types of cytoplasmic granules, developed sequentially during cell maturation. The different subtypes of granules have unique protein content and functional characteristics. The formation of each granule subtype coincides with the biosynthesis of its content. READ MORE

5. 3. Wise Process Routes for Varying Feedstock in Base Metal Extraction : Modelling of a Peirce-Smith Converter and Investigation of Buildup Formation in an Electric Smelting Furnace

   Author : Andreas Lennartsson; Pekka Taskinen; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Abstract : Copper, like silver and gold, is one of the metals that are known to have been worked by some of the oldest civilisations on record. It is used forits unique properties such as corrosion resistance, good workability, high thermal conductivity and attractive appearance. READ MORE

6. 4. 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

7. 5. 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
