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 ... -
Effects of ultrasound on desliming prior to feldspar flotation
Malayoğlu, Ufuk; Özkan, Şafak Gökhan (Mdpi, 2019)In this study, the effects of ultrasound on removal of impurities from raw feldspar were investigated by testing with a newly developed flotation cell with various frequency and power intensities prior to multistage feldspar ... -
Enhancement of galena-potassium ethyl xanthate flotation system by low power ultrasound
Güngören, Can; Baktarhan, Yasin; Demir, Ismail; Özkan, Şafak Gökhan (Elsevier, 2020)The objective of this study is to investigate the improvement possibilities of the floatability of galena with ultrasonic application in the presence of potassium ethyl xanthate (KEX). For this purpose, micro-flotation ... -
An improvement on selective separation by applying ultrasound to rougher and re-cleaner stages of copper flotation
Hassanzadeh, Ahmad; Sajjady, Sayed Ali; Gholami, Hamed; Amini, Saeed; Özkan, Şafak Gökhan (Mdpi, 2020)It has been known that the power ultrasound is used as a pretreatment and rarely applied as a simultaneous method to improve grade and recovery during froth flotation processes. This work aimed at investigating the impact ... -
