  1. 6. Influences of palladium ceramics on valuable metal losses to a PbO-SiO2-Sb2O3 based silver smelting slag.

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Per Kautto; [2020]
    Keywords : palladium ceramics; silver smelting slag; PbO-SiO2-Sb2O3;

    Abstract : Silver and palladium can be found in the so called palladium-ceramics which comes from catalyst production. These valuable metals needs to be recovered from these wastes in order to further increase both the environmental and economic sustainability of our society. READ MORE

  3. 7. Effect of filtration aid on downstream processing of polymer particles : Effektivisering av avvattningsprocessen av polymerpartiklar

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Emma Johansson; [2019]
    Keywords : ;

    Abstract : Polymer particles are expandable and produced by Nouryon. The production consists of polymerization, dewatering and drying. Dewatering of polymer particlesis an important part of the production process and have a large impact on how efficient the downstream process can be performed. READ MORE

  4. 8. Secondary Steel Metallurgy Slag Design and MgO-C Refractory Implications : Theoretical and Practical Considerations

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Hellgren Simon; [2019]
    Keywords : MgO-C; CaO-SiO2-Al2O3-MgO; Slag Design; Refractory Wear;

    Abstract : MgO-C based refractory materials, often used in secondary steel making, are exposed to variouswear mechanisms in its application. The wear could be divided into oxidative, chemical andabrasive categories, all behaving differently and all being influenced by different factors. READ MORE

  5. 9. Influence of bio-coal ash respectively coal structure on coke production and coke quality

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

  6. 10. Partitioning of Zn and Cr in Basic Oxygen Steelmaking

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Andreas Persson; [2019]
    Keywords : Partitioning; Cr; Zn; BOS;

    Abstract : Steel is the worlds most used metal and 2016 the produced amount of steel was measured to a total1630 MT where the Blast Furnace (BF) - Basic Oxygen Steelmaking (BOS) process, which is the mostcommon steel process, stands for 75% of the world’s current crude steel production.The BOS process works by blowing oxygen at high velocity through a hot metal bath consisting of hotmetal from the blast furnace mixed with fluxing agents as slag formers and up to 30 weights% scrap.
