Sofia University “St. Kliment Ohridski” (SU) is the highest ranked and the oldest Bulgarian University with more than 20 000 students. It covers all the disciplines of the natural and social sciences. The faculty of chemistry and pharmacy at SU, as a counterpart possesses a large toolbox of equipment, able to hold any experimental task related with the flotation of mineral particles/ions as for example chemical analysis (ICP-MS, UV, IR, XRD, NMR, EPR, Chromatography, etc.), visualization (SEM, TEM, AFM, Viz. Microscopy, DLS, etc.), force map analysis (AFM, tensiometry, goniometry, TLF experimental setup, etc.), complex analysis of foam, tests on micro-flotation on particles and ions under lab conditions, etc. Moreover, we are intrinsically associated with the Bulgarian School of Physical Chemistry and hence, our team is strong in modelling the surface forces in thin liquid films between bubble and particle, bubble and bubble and can suggest solutions for their control in direction on demand. Overall, we are able to execute tasks related with optimization of flotation efficiency with specific requirements under lab conditions, perform theoretical modelling and suggest particular solutions of flotation problems.
