    • Chelating Adsorbents in Purification of Hydrometallurgical Solutions 

      Sirola, Katri
      Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 11.12.2009)
      In this thesis, equilibrium and dynamic sorption properties of weakly basic chelating adsorbents were studied to explain removal of copper, nickel from a concentrated zinc sulfate solution in a hydrometallurgical process. ...

    • Hydrometallurgical recovery of valuable metals from secondary raw materials 

      Virolainen, Sami
      Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 11.12.2013)
      Wastes and side streams in the mining industry and different anthropogenic wastes often contain valuable metals in such concentrations their recovery may be economically viable. These raw materials are collectively called ...

    • Reaction Kinetics and Viscosity Modelling in the Fusion Syntheses of Ca- and Ca/Mg-resinates 

      Sundqvist, Satu
      Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 18.12.1999)
      Rosin is a natural product from pine forests and it is used as a raw material in resinate syntheses. Resinates are polyvalent metal salts of rosin acids and especially Ca- and Ca/Mg- resinates find wide application in the ...

    • Recovery and refining of manganese as by-product from hydrometallurgical processes 

      Pakarinen, Jouni
      Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 28.10.2011)
      The consumption of manganese is increasing, but huge amounts of manganese still end up in waste in hydrometallurgical processes. The recovery of manganese from multi-metal solutions at low concentrations may not be economical. ...

    • The Role of Surfactant Properties of Extractants in Hydrometallurgical LiquidLiquid Extraction Processes 

      Jääskeläinen, Eduard
      Acta Universitatis Lappeenrantaensis (Lappeenranta University of Technology, 20.10.2000)
      The amphiphilic nature of metal extractants causes the formation of micelles and other microscopic aggregates when in contact with water and an organic diluent. These phenomena and their effects on metal extraction were ...
