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 ... -
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 ...
