Article Effect of Dextrin on Pyrite Depression in Sulfide Cu Ore Flotation Using Response Surface Methodology(Springer, 2026-02-12) Taner, Hasan Ali; Aras, Ali; Ismail, AyazIn this study, the effect of dextrin as a depressant in the flotation of a pyrite-containing sulfide copper ore sample was investigated. The central composite design (CCD) method was used to investigate the effect of dextrin in the flotation experiments. The effects of variables such as pH, depressant amount, and collector amount on copper (Cu) and iron (Fe) grades and recoveries were optimized and modeled. The zeta potential values and sedimentation behavior of the sample were determined, and the concentrates obtained from the flotation experiments were analyzed using SEM-EDS and FTIR. Flotation results indicated that dextrin had a good depressant effect on pyrite and was successful in separating chalcopyrite from pyrite. Pyrite depression is thought to be caused by increased surface hydrophilicity, which is due to the abundant OH- groups in the dextrin structure and the high pH. SEM and SEM-EDS analyses revealed high Fe, S, Si, and O contents in the sample, while the concentrate obtained at the optimum experiment had high Cu and low Si and O contents. Dextrin has been determined to have the potential to be used as a selective, non-toxic, and environmentally friendly depressant for the depression of pyrite in Cu flotation.Article Citation - WoS: 3Application of the Shrinking-Core Models for Determination of Dissolution Kinetics of Mn and Zn From Spent Zinc-Carbon Battery Powder in Organic Acid Solution(SCIENDO, 2019-06-01) Ağaçayak, Tevfik; Taner, Hasan AliIn this study, dissolution kinetics of manganese and zinc from spent zinc-carbon batteries in acetic acid solution was investigated. To determine the kinetics of dissolution of manganese and zinc, shrinking core model was applied to dissolution recoveries obtained at different temperatures. As a result of kinetic studies, it was determined that manganese and zinc were dissolved in acetic acid solution by diffusion from product layer and then activation energies (Ea) were calculated.Article Citation - WoS: 6Citation - Scopus: 6Solvent Extraction of Manganese and Zinc From Chloride Leach Solution of Spent Zn–c Batteries With Dehpa in Benzene Diluent(Springer Science and Business Media Deutschland GmbH, 2024-03-25) Abdelraheem, M.T.O.; Aras, A.; Taner, H.A.; Agacayak, T.The applicability of utilizing solvent extraction processes of manganese (Mn) and zinc (Zn) from chloride leachate of spent zinc–carbon (Zn–C) batteries has been studied by using di-2-ethylhexyl phosphoric acid (DEHPA) as an extractant agent. The effect of five factors (equilibrium pH, O/A ratio, temperature, extractant concentration, and diluent type) were investigated. According to the results gained, the appropriate solution pH level for DEHPA was found to be 6.5. With DEHPA (20%, v/v), 77.50% Mn and 100% Zn were extracted, within 15 min contact time at a 1:1 aqueous/organic ratio and 50 °C temperature. Also, a McCabe–Thiele diagram was drawn and one single-step extraction for Zn and a two-stage process for Mn were needed to achieve the highest extraction efficiency. ΔH as a thermodynamic parameter was calculated and found to be 18.39 kJ/mol for Mn and − 245.50 kJ/mol for Zn, respectively, indicating that the extraction process was endothermic for Mn and exothermic for Zn. A desirable stripping of Mn and Zn from the loaded organic phase could be obtained using a stripping solution of 6 M HCl.

Bununla birlikte, kömürün yan kayaç olarak kil minerallerini bulundurması flotasyon işlemini olumsuz etkilemektedir. Bu çalışmada kil minerallerinin (kaolin ve montmorillonit) ve flotasyon reaktiflerinin Tunçbilek linyit kömürünün flotasyon performansına ve ortalama kabarcık boyutuna etkisi araştırılmıştır. Deneysel çalışmalarda; bastırıcı olarak sodyum silikat, toplayıcı olarak gaz yağı kullanılırken, köpürtücü olarak ise metil izobütil karbinol (MIBC) ve Dowfroth 250 kullanılmıştır. Kil türü ve miktarı, bastırıcı miktarı ve köpürtücü türü ve miktarı çalışılan deneysel parametrelerdir. Bastırıcı miktarı ve kil içeriğinin etkisinin belirlendiği deneysel çalışmalarda, kaolin içerikli numunelerde %40-55, montmorillonit içerikli numunelerde ise %30-47 aralığında yanabilir verim değerleri elde edilmiştir. Köpürtücü olarak Dowfroth 250 ile daha iyi sonuçlar elde edilmiş ve montmorillonit içeren kömür numunesi, kaolin içeren kömür numunesine göre daha büyük kabarcıklar oluşmasına neden olmuştur. Bu çalışmadan elde edilen sonuçlar yan kayaç olarak kil bulunduran kömürlerin flotasyon davranışlarının anlaşılabilmesi ve çözüm önerileri sunulabilmesi için temel bir altyapı oluşturacaktır.Article Citation - WoS: 4Citation - Scopus: 4Study of Chalcopyrite Flotation in the Presence of Illite Using a Design of Experiments Approach(Cambridge Univ Press, 2021-09-01) Taner, Hasan Ali; Önen, VildanThe interaction between chalcopyrite and illite particles was analysed using zeta-potential measurements and flotation tests. Statistically designed tests were used to examine the factors controlling flotation (frother concentration, dispersant concentration, froth height, airflow rate and amount of clay). Furthermore, the significance levels of the impacts of these factors on responses (chalcopyrite grade/recovery, pyrite grade/recovery, dynamic froth stability and mean bubble diameter) were determined. Chalcopyrite and pyrite zeta-potentials were measured in the presence of illite. The addition of 15% illite to the chalcopyrite, especially between pH 11 and 12, shifted the zeta-potential values closer to that of pure illite, indicating complete surface coating of chalcopyrite with illite. In the flotation experiments, better results were obtained in terms of chalcopyrite grade at a low airflow rate and a high froth height. With increasing froth height there was a decline in the gangue mineral recovery as the residence time of the froth increased. The most significant factor increasing pyrite recovery was the amount of clay. Although illite is considered to be the least problematic clay mineral for flotation, as reported in the literature, an illite content of as low as 5% in the ore decreased chalcopyrite grade by 3.83%. While K and Na contents of 4% were detected after flotation without the addition of illite, their abundance increased to 5.7% after the addition of illite.Article Ocaktan Endüstriye: Mermer Atıklarından Mikronize Kalsit Üretimine Yönelik Eleştirel Derleme ve Deneysel Vaka Çalışması(2025-12-31) Yilmaz, Serdar; Taner, Hasan Ali; Toroğlu, İhsan; Bilen, MehmetBu makale, (i) mermer atığı değerlendirmenin yolları ve endüstriyel kalite kalsiyum karbonat (CaCO₃) içinpazar/teknik gereksinimlere dair kritik bir literatür taraması ve (ii) mermer işleme atığının mikronize edilmesineyönelik laboratuvar ölçeğinde yapılmış bir deneysel vaka çalışmasını birleştiren bir hibrit çalışmayı sunmaktadır.Eskişehir'deki bir işleme tesisinden alınan örneklerin kimyasal karakterizasyonu (XRF), yüksek CaCO₃ saflığını(98.93%) doğrulamıştır. Deneysel çalışma, zirken taşı öğütme bilyeleriyle donatılmış bir iğne tipi dikeykarıştırmalı medya öğütme değirmeni kullanarak, dönüş hızının (360–1440 rpm), dolum oranının (nominal %60–140) ve öğütme süresinin (15–600 saniye) parçacık boyut dağılımı üzerindeki etkilerini araştırmıştır. Öğütmetestlerinin amacı, endüstriyel dolgu maddeleri için uygun olan mikronize yüksek saflıktaki kalsitin üretilebilirliğinideğerlendirmektir (hedef d₅₀ < 10 μm, kağıt/kaplamalar/plastikler için). Sonuçlar, uygun hız ve zamankombinasyonlarının (örneğin, yüksek hızda 300 saniye) d₅₀ ≈ 9.6 μm ürettiğini, ancak uzun süreli öğütmenin (>180saniye bazı koşullarda) aglomerasyona yol açtığını ve ısınma ve aşınma nedeniyle verimliliği azalttığınıgöstermektedir. Makale, bu deneysel bulguları değerleme yolları ile ilişkilendirir ve ölçekleme ve endüstriyeluygulama için pratik işlem önerileri (örneğin, dispersan kullanımı, ön işleme) sunar. Hibrit yapı, literatür bilgilerive hedeflenmiş deneylerin bir arada nasıl mermer atığını yüksek değerli mikronize kalsit için uygun bir kaynakolarak doğrulayabileceğini göstermektedir.Article Citation - WoS: 12Mechanism of Mechanical Entrainment in Chalcopyrite Flotation: Effects of Clay Minerals(Springer Heidelberg, 2023) Taner, Hasan Ali; Önen, VildanOne of the problems in flotation is mechanical entrainment and the other is the presence of complex gangues (especially clay minerals). In the present study, it was aimed to determine the effects of clay types (kaolinite, illite, and montmorillonite) on mechanical entrainment parameters (total flotation recovery, real recovery, mechanical entrainment recovery, and water recovery). Effects of clay types and clay amount on chalcopyrite flotation were investigated by flotation experiments. Interaction mechanisms between the clay minerals and ore were characterized using SEM-EDS analyses. Experiments were carried out with and without a collector using the mixture of clay minerals and ore under certain experimental conditions. While the clay mineral most affecting the chalcopyrite grade was montmorillonite, the highest mechanical entrainment recovery and the lowest real recovery values were obtained in the presence of illite. While illite is stated as the least problematic clay mineral in the literature, it was determined that illite among three clay minerals used in this study caused significant mechanical entrainment. In contrast, it was determined that increasing the amount of kaolinite did not have a significant effect on mechanical entrainment. This study's findings will guide in determining of clay minerals' effect on gangue entrainment in flotation.Article Optimization of Flocculation/Coagulation Conditions of Coal Preparation Plant Tailings Using Chitosan and FeCl3 Through Experimental Design(MDPI, 2026-03-12) Taner, Hasan Ali; Nyanswe, Augustino HenryCoal preparation plants generate large volumes of fine tailings containing negatively charged colloidal particles that remain stable in suspension and hinder efficient water recovery. In this study, the flocculation performance of coal tailings was statistically evaluated using inorganic and organic reagents, namely ferric chloride (FeCl3) and chitosan. The effects of chitosan dosage, FeCl3 dosage, pH, stirring speed, and pulp density on turbidity and water recovery were investigated through Response Surface Methodology (RSM). Zeta potential measurements revealed that the sample exhibited a negative surface charge over the entire pH range. In contrast, chitosan effectively shifted the surface charge toward positive values under acidic and near-neutral conditions, indicating charge neutralization and polymer bridging mechanisms. ANOVA results revealed that pH, chitosan dosage, and pulp density were the most significant parameters influencing turbidity and water recovery. Under optimized conditions, turbidity was reduced to 9.86 NTU with a water recovery of 76.92%. Using chitosan alone provided an effective and statistically validated strategy for dewatering samples by enhancing floc formation through combined charge neutralization and interparticle bridging mechanisms, resulting in minimal turbidity. Although chitosan alone was sufficient to achieve effective flocculation, its synergistic combination with FeCl3 resulted in the highest water recovery values under optimized conditions.Doctoral Thesis Kil Minerallerinin Yapısal Özelliklerinin Metal Sülfürlerin Flotasyon Performansına Etkisi(Konya Teknik Üniversitesi, 2019) Taner, Hasan Ali; Önen, VildanBu çalışmada, kil minerallerinin kalkopirit flotasyonundaki etkilerinin ortaya konulması ve flotasyonda başarılı sonuçlar elde etmek için çözüm önerileri sunulması amaçlanmıştır. Deneysel çalışmalar; zeta potansiyeli ve temas açısı ölçümleri, flotasyon deneyleri, kil minerallerinin flotasyon tenör/verim/köpük kararlığına, flotasyon kinetiğine ve mekanik taşımaya etkisinin belirlendiği deneyler ile tesis numunesi için farklı bastırıcı/dağıtıcıların kullanıldığı deneyleri kapsamaktadır. Kil minerallerinin etkisinin araştırıldığı deneysel çalışmalarda istatistiksel deney tasarım yöntemlerinden merkezi kompozit tasarımı kullanılmıştır. Deneylerde bağımsız değişkenler; köpürtücü miktarı, dağıtıcı miktarı, köpük derinliği, hava akış hızı ve kil miktarı seçilmiştir. Sonuçların değerlendirilmesinde bağımlı değişkenler; kalkopirit tenörü ve verimi, pirit tenörü ve verimi, dinamik köpük kararlılığı ve ortalama kabarcık çapı olarak belirlenmiştir. Kilin etki mekanizmasını belirlemek için SEM, SEM-EDS, TOC ve FTIR analizleri yapılmıştır. Kil miktarı arttıkça kalkopirit tenörü düşmüş; verim, köpük kararlılığı ve kabarcık boyutu artmıştır. Verim ve tenör açısından olumsuz etki önem sırası montmorillonit>kaolin>illit, dinamik köpük kararlılığı açısından kaolin>montmorillonit>illit şeklinde belirlenmiştir. En büyük kabarcık çapı montmorillonit ile elde edilmiştir. Etkin mekanizma mekanik taşıma olarak belirlenmiştir. Uygun bir flotasyon için kil tipi (kaolin, illit ve montmorillonit) ve oranına bağlı olarak uygulanabilecek flotasyon şartları matematiksel olarak modellenmiştir. Böylece tesis içerisinde zamanla değişen kil oranına bağlı olarak modelde yer alan çalışma parametrelerinde yapılabilecek değişiklikler ile flotasyon sonucunda ulaşılabilecek verim-tenör değerlerinin öngörüsü sağlanabilecektir.Article Citation - WoS: 2Citation - Scopus: 3The Effect of Different Clay Minerals on the Flotation Kinetics of Chalcopyrite(Technical University of Kosice, 2022-12-08) Taner, H.A.; Önen, V.This study investigated the effects of clay minerals (montmorillonite, illite, and kaolinite) on chalcopyrite recovery and flotation kinetic parameters. Classical first-order flotation kinetic model was applied as a function of froth height and amount of clay minerals to fit overall flotation results on chalcopyrite recovery against flotation time. Clay minerals enhanced chalcopyrite recovery by mechanical entrainment and slime coating of valuable chalcopyrite particles. Flotation tests have shown that the deleterious impact of clay minerals on the chalcopyrite flotation is enhanced as follows: montmorillonite>kaolinite>illite. Montmorillonite significantly raised viscosity and also considerably diminished chalcopyrite grade. Recovery and selectivity were lower for montmorillonite than kaolinite and illite. The adjunct of illite was of little effect on chalcopyrite flotation kinetics. The obtained flotation rate constants indicate that clay minerals are carried to the concentrate together with the chalcopyrite. The flotation rate constants increased with increasing the amount of all clay minerals. Slime minerals easily entered to concentrate by mechanical entrainment, and the inhibition effect of clay particles on chalcopyrite became more obvious with increasing flotation time. However, the negative effect of clay minerals is reduced with high froth height. © 2022 by the authors.
