Effect of chloride salt Ions onto coal flotation based on contact angle and bubble-particle attachment time
Özkan, Şafak Gökhan; Güngören, Can; Baktarhan, Yasin; Özdemir, Orhan; Şahpaz, Orhan; Kurşun, İlgin (2022)This study was aimed to reveal the effect of K+, Na+, Ca2+, and Mg2+ ions on the bubble-particle interactions of high-rank coal with contact angle and bubble-particle attachment time studies. The results for the contact ... -
Effect of conventional and microwave thermal treatments on floatability of low- and high-rank lignites
Özkan, Şafak Gökhan; Baktarhan, Yasin; Demir, İsmail; Güngören, Can (Energy Sources Part A-Recovery Utilization and Environmental Effects, 2020)Thermal treatment is one of the well-known methods used before froth flotation to remove the polar groups from coal surfaces to make them more hydrophobic. In this study, the effect of conventional and microwave thermal ... -
Effect of operating parameters on the breakage process of calcite in a stirred media mill
Özkan, Şafak Gökhan; Katıcıoğlu-Bayel, Diler; Toraman, Öner Yusuf (Mining, Metallurgy & Exploration, 2019)One of the most energy-intensive processes for producing submicron range calcite is stirred media mill. In the present work, numerous operating parameters such as solid mass fraction, grinding media size, media filling ... -
Effect of power ultrasound on wettability and collector-less floatability of chalcopyrite, pyrite and quartz
Hassanzadeh, Ahmad; Gholami, Hamed; Özkan, Şafak Gökhan; Niedoba, Tomasz; Surowiak, Agnieszka (MDPI-Multidisciplinary Digital Publishing Institute, 2021)Numerous studies have addressed the role of ultrasonication on floatability of minerals macroscopically. However, the impact of acoustic waves on the mineral hydrophobicity and its physicochemical aspects were entirely ... -
Investigation of the effect of polymer-based novel grinding aids on cement grinding efficiency
Özcan, Ebru Dengiz; Çinku, Kenan; Özdamar, Şenel; Ergin, Hasan; Özkan, Şafak Gökhan (Wiley, 2021)Grinding aids, primarily amine group chemicals, are used to reduce agglomeration and increase concrete strength in order to ensure an efficient comminution process in the modern cement industry. This paper aims to investigate ... -
Ultrasound supported flocculation of borate tailings with differently charged flocculants
Özkan, Şafak Gökhan; Demir, İsmail; Güngören, Can; Baktarhan, Yasin; Yücel, Melike; Çinku, İlgin; Kurşun, İlgin (Journal of Boron, 2021)Mining activities are followed by mineral processing and wet beneficiation methods which generate a significant amount of tailings. Slime fractions are discharged to the tailing ponds with associated process water and this ... -
