  1. 1. Possibilities to use industrial oxidic by-products as neutralising agent in bioleaching and the effect of chloride on biooxidation

    Författare :Chandra Sekhar Gahan; S. Subramanian; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Sammanfattning : The cost for neutralisation is the second largest cost in a bioleaching operation for which, possibilities to replace generally used lime/limestone was tested. Industrial oxidic by-products generated form Swedish industries were investigated for neutralising capacities by chemical leaching with sulphuric acid at pH 1. LÄS MER

  3. 2. Towards Abatement of Selected Emissions from Metals Manufacturing

    Författare :Diana Orrling; Seshadri Seetharaman; S. Subramanian; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mercury; zinc; iron; copper; sulfur dioxide; adsorption; pollution; spectroscopy; thermal desorption; polycrystalline; surfaces; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Although the metallurgical industry has made great strides in the reduction of unwanted emissions to the atmosphere as a result of production processes, significant challenges still exist. From a global perspective, even large reductions in emissions per produced ton become immaterial when considering that the total world production of metals continues to increase. LÄS MER

  4. 3. Novel strategies for C-C/X bond formation
