  2. 1. Studies on the Recovery of Secondary Antimony Compounds from Waste

    Author : Toni Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Morphology; Thermolysis; Leaching; Municipal Solid Waste; Zinc; Metal Oxide Varistor; Cementation; Fly Ash; Recycling; Antimony;

    Abstract : The global supply of antimony is dominated by one country which has led the European Union to classify antimony as a critical raw material. Other than the rare-earth elements antimony has the highest supply risk. Therefore, a feasibility study on the recycling of antimony and antimony compounds is of great importance. READ MORE

  6. 4. Cementation of cyanidation tailings – effects on the release of As, Cu, Ni and Zn

    Author : Roger Hamberg; Christian Maurice; Lena Alakangas; Mamadou Fall; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geochemistry; Tillämpad geokemi;

    Abstract : Knowledge about mineralogy and chemical composition in sulfidic tailings is essential to predict how tailings management may affect the future leachate quality. At a gold mine in the north of Sweden, gold was extracted from inclusions in arsenopyrite and pyrrhotite by the use of cyanide. READ MORE

  7. 5. Diagenesis and Sequence Stratigraphy : an integrated approach to constrain evolution of reservoir quality in sandstones

    Author : João Marcelo Ketzer; Karl Ramseyer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; mineralogi; petrologi och tektonik; Mineral Chemistry; Petrology and Tectonics;

    Abstract : Diagenesis and sequence stratigraphy have been formally treated as two separate disciplines in sedimentary petrology. This thesis demonstrates that synergy between these two subjects can be used to constrain evolution of reservoir quality in sandstones. READ MORE
