  1. 1. Antimony recovery from complex copper concentrates through hydro- and electrometallurgical processes

    Författare :Samuel Ayowole Awe; Olof Forsén; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : Today, one of the major difficulties confronted during copper metallurgy is the elimination of antimony and arsenic impurities from the process. This is because the pure copper ore reserves are becoming exhausted and the resources of unexploited ores often contain relatively high amounts of antimony and arsenic. LÄS MER

  3. 2. In-situ activated hydrogen evolution from pH-neutral electrolytes

    Författare :John Gustavsson; Ann Cornell; Olof Forsén; KTH; []
    Nyckelord :molybdate; trivalent cations; electrolysis; hypochlorite reduction; films; electrolysis; chlorate process; molybdat; trivalenta katjoner; elektrolys; hypokloritreduktion; filmer; kloratprocessen; SRA - Energy; SRA - Energi;

    Sammanfattning : The goal of this work was to better understand how molybdate and trivalent cations can be used as additives to pH neutral electrolytes to activate the Hydrogen Evolution Reaction (HER). Special emphasis was laid on the chlorate process and therefore also to some of the other effects that the additives may have in that particular process. LÄS MER
