Adsorption of dithiophosphate and dithiophosphinate on chalcopyrite
Guler, T; Hicyilmaz, C; Gokagac, G; Ekmeci, Z (PERGAMON-ELSEVIER SCIENCE LTD, 2006)Electrochemical behavior of chalcopyrite was investigated in the absence and presence of dithiophosphate (DTP) and dithiophosphinate (DTPI), selective thiols against Fe-sulfides in the flotation of sulfide ores, in ... -
Dithiophosphinate-pyrite interaction: Voltammetry and DRIFT spectroscopy investigations at oxidizing potentials
Guler, T (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005)The electrochemistry of dithiophosphinate (DTPI) adsorption on pyrite was investigated by cyclic voltammetry (CV) and diffuse reflectance infrared Fourier transformation (DRIFT) spectroscopy at oxidizing potentials under ... -
Electrochemical behaviour of chalcopyrite in the absence and presence of dithiophosphate
Guler, T; Hicyilmaz, C; Gokagac, G; Ekmekci, Z (ELSEVIER SCIENCE BV, 2005)Electrochemical behaviour of chalcopyrite was investigated in collectorless condition and in the presence of dithiophosphate (DTP), which is a selective collector for chalcopyrite, by cyclic voltammetry (CV) study. Diffuse ... -
Flotation and entrainment behavior of minerals in talc-calcite separation
Akdemir, U; Guler, T; Yildiztekin, G (BLACKWELL PUBLISHING, 2005)The main aim of a flotation process is to recover the valuable part of the ore with minimum gangue contamination by different mechanisms, such as entrainment. In this study, the flotation rate and recovery of talc and ... -
Hydrophobicity of chalcopyrite with dithiophosphate and dithiophosphinate in electrochemically controlled condition
Guler, T; Hicyilmaz, C (ELSEVIER SCIENCE BV, 2004)The degree of hydrophobicity of chalcopyrite was determined by contact angle measurements on polished chalcopyrite surface in electrochemically controlled conditions. Results have shown that the increase in solution pH ... -
Role of some physical variables on gangue and water recovery in froth
Akdemir, U; Guler, T (A A BALKEMA PUBLISHERS, 2000)In this research, flotation recovery and entrainment, of fine gangue were investigated using calcite as hydrophilic and talc as hydrophobic mineral. For this purpose water, talc and calcite recoveries within froth product ... -
Voltammetric and drift spectroscopy investigation in dithiophosphinate-chalcopyrite system
Guler, T; Hicyilmaz, C; Gokagac, G; Ekmekci, Z (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2004)The mechanism of dithiophosphinate (DTPI) adsorption on chalcopyrite was investigated by diffuse reflectance Fourier transformation (DRIFT) spectroscopy and by cyclic voltammetry (CV) at various pHs. CV experiments showed ...
