  • Adsorption Kinetics of Various Frothers on Rising Bubbles of Different Sizes under Flotation Conditions 
    Batjargal, Khandjamts; Guven, Onur; Ozdemir, Orhan; Karakashev, Stoyan I.; Grozev, Nikolay A.; Boylu, Feridun; Celik, Mehmet Sabri (MINERALS / MDPI, 2021-03)
    This paper studies the effect of the type and concentration of selected frothers, the gas flowrate, and the pore size of the porous frit on the bubble sizes (Sauter mean diameter, SMD) of bubbling flow produced in a ...
  • Bubbling properties of frothers and collectors mix system 
    Batjargal, Khandjamts; Guven, Onur; Ozdemir, Orhan; Karakashev, Stoyan I.; Grozev, Nikolay A.; Boylu, Feridun; Celik, Mehmet Sabri (PHYSICOCHEMICAL PROBLEMS OF MINERAL PROCESSING / OFICYNA WYDAWNICZA POLITECHNIKI WROCLAWSKIEJ, 2022-08)
    This paper studies the effect of the type and concentration of selected frothers and collectors mix system on the bubble sizes (Sauter mean diameter, SMD) of bubbling flow produced in a micro flotation cell and the ...
  • Correlations for Easy Calculation of the Critical Coalescence Concentration (CCC) of Simple Frothers 
    Karakashev, Stoyan I.; Grozev, Nikolay A.; Batjargal, Khandjamts; Guven, Onur; Ozdemir, Orhan; Boylu, Feridun; Celik, Mehmet Sabri (COATINGS / MDPI, 2020-07)
    Can the critical coalescence concentration (CCC) of the flotation frothers be predictable? What is the relation between their molecular structure and their CCC values? A literature survey found specific correlations between ...
  • Experimental Procedure for the Determination of the Critical Coalescence Concentration (CCC) of Simple Frothers 
    Guven, Onur; Batjargal, Khandjamts; Ozdemir, Orhan; Karakashev, Stoyan I.; Grozev, Nikolay A.; Boylu, Feridun; Celik, Mehmet Sabri (MINERALS / MDPI, 2020-07)
    In this study, the critical coalescence concentrations (CCC) of selected commercial frother solutions, namely polypropylene glycols (PPG 200, 400, and 600), tri propylene glycol (BTPG), triethylene glycol (BTEG), dipropylene ...
  • On the frother's strength and its performance 
    Karakashev, Stoyan I.; Grozev, Nikolay A.; Ozdemir, Orhan; Batjargal, Khandjamts; Guven, Onur; Ata, Seher; Bournival, Ghislain; Boylu, Feridun; Celik, Mehmet Sabri (MINERALS ENGINEERING / ELSEVIER LTD., 2021-09)
    It is a common rule that the strength of the frother is assessed by either its dynamic foamability index (DFI) or its critical coalescence concentration (CCC). The smaller the value of CCC the stronger the frother is. This ...
  • Physical restrictions of the flotation of fine particles and ways to overcome them 
    Stoyan, I. Karakashev; Grozev, Nikolay A.; Ozdemir, Orhan; Guven, Onur; Ata, Seher; Bournival, Ghislain; Batjargal, Khandjamts; Boylu, Feridun; Hristova, Svetlana; Celik, Mehmet Sabri (PHYSICOCHEMICAL PROBLEMS OF MINERAL PROCESSING / OFICYNA WYDAWNICZA POLITECHNIKI WROCLAWSKIEJ, 2022-09)
    This work analyses the basic problems of the fine particles flotation and suggests new ways to overcome them. It is well accepted that the poor recovery of fine particles is due to the small collision rate between them and ...
