  1. 1. Evaluation of Scale-up Model for Flotation with Kristineberg Ore

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Adam Isaksson; [2018]
    Keywords : flotation; HSC; Kristineberg; locked cycle; mass balancing; mixed cycle; open circuit; scale-up; blandkrets; flotation; HSC; Kristineberg; sluten krets; massbalansering; öppen krets; uppskalning;

    Abstract : The objectives of this project were to survey the flotation circuit of the Boliden concentrator, mass balance collected data and evaluate a scale-up model for laboratory flotation results. The model assumes that half of the recovery to cleaner middlings in a standard laboratory test would report to the final concentrate if it were done in closed circuit, as is the case in a full-scale plant.

  3. 2. STM-based characterization of single GaInP photovoltaic nanowires

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Johannes Brask; [2016]
    Keywords : STM top contact method GaInP nanowire array solar cell; Physics and Astronomy;

    Abstract : The I-V and photovoltaic properties of III-V semiconducting GaInP nanowires have been studied using a scanning tunneling microscope (STM) in evaluation for usage as a potential "sub cell" in a nanowire based tandem solar cell configuration. This evaluation required precise I-V characterization and photo response measurements of individual nanowires. READ MORE

  4. 3. Design of a Real-Time Model of a Photovoltaic Panel

    University essay from KTH/Elektrisk energiomvandling

    Author : Markus Fjällid; [2015]
    Keywords : Power electronics; Photovoltaic panel; Buck converter; Interleaved switching;

    Abstract : Photovoltaic panels are widely used to harvest solar energy. In the general application the panels are connected to an inverter that allows the power to be feed to the grid. The possibility to emulate a photovoltaic panel in a laboratory environment simplifies the development of inverters. READ MORE
