Ivanov Irkutsk National Research Technical University 83 Lermontova, Irkutsk, 664074, Russia Received 19.03.2016, received in revised form 20.05.2016, accepted 02.07.2016 This paper presents theoretical calculations and the results of laboratory experiments showing that almost all quartzite, carried away as a fi ne dust phase in gas removal and gas cleaning, presented spheroidized micro- and nanoparticles of SiO2 . <...> The best process for extracting the associated carbon nanotubes is fl otation. <...> Floating particles of micro and nano-sized particles should be carried out in a laminar fl ow of the pulp with the fewest basic fl otation cycles. <...> Initial bubbles emerging from the aerator must be close to monodisperse distribution. <...> As the aerator should be used pneumohydraulic aerator. <...> To activate hydrophilized particles of valuable component need to use pressure fl otation. <...> To reduce energy consumption and time of fl otation need the smallest number of elementary cycles of fl otation (ETSF). <...> The results of theoretical and practical studies of fl otation of nanoscale silicon structures, J. <...> All rights reserved * Corresponding author E-mail address: kvv@istu.edu # 657 # Victor V.
