    The aim of this study was to obtain a high grade and yield percentage of iron concentratefrom a specularite ore by using wet magnetic separation and reverse flotation techniques.The processing a specularite sample using wet magnetic separation and reverseflotation method was studied. During the magnetic separation process, particle size was-2000 μm and magnetic field applied at 0.25 T and 0.85 T which were performed at asolid-liquid ratio of 10% and 20% by weight, respectively. In the reverse flotation tests,experimental design (DOE) was applied, statistically. Depressant dosage, collector dosageand flotation time were selected as main parameters. PH value, frother dosage (MIBC) andparticle size were constant parameters. The results showed that particle size and magnetic fieldintensity had a significant effect on the iron concentrate grade and yield for wet magneticseparation. The optimum value of iron concentrate grade was 98.75% at 0.25 T andparticle size of -150 μm while the highest value of iron concentrate yield was 67% at 0.75T and particle size of -74 μm. In the flotation tests, depressant dosage had the greatestinfluence on the iron concentrate grade while the effect of the collector dosage and frothcollection time were less. Froth collection time had the greatest effect on iron concentrateyield.The maximum iron concentrate grade was 90.13% for the following conditions:5250 g/ton depressant, 1000 g/ton collector and 2-minute froth collection time. Themaximum iron concentrate yield was 98.96% for the following conditions: 5250 g/tondepressant, 1500 g/ton collector and 1 min froth collection time under fixed conditions.

    Production of Mn3O4 Nanoparticles From a Manganiferous Iron Ore via Reductive Leaching, Precipitation, and Calcination
    (Elsevier, 2022-02) Altiner, Mahmut; Top, Soner; Bouchekrit, Chafia; Kursunoglu, Sait
    The synthesis of Mn3O4 nanoparticles from a manganiferous iron ore through reductive leaching, precipitation, and calcination was investigated. The reductive leaching results showed that Mn (99.9%) was almost completely extracted into the leaching solution along with a substantial amount of Mg (99.9%), Al (99.5%), Ca (80%), and Fe (22.9%) under the following conditions: 30 g/L tartaric acid as a reducing agent, 1 M HCl solution, leaching temperature of 90 ?, and leaching duration of 3 h. In the first precipitation step, Fe and Al were expelled from the pregnant leach solution by the addition of NaOH prior to conducting the precipitation experiments for the production of manganese carbonate (MnCO3) particles from the purified solution. In the second precipitation step, MnCO3 particles were produced using sodium carbonate (Na2CO3) as the precipitating agent. The effects of parameters such as reaction temperature, Na2CO3 concentration, and experimental duration were investigated using the Taguchi approach. Manganse(II) was precipitated in the form of MnCO3 particles (97.4%) under the following conditions: a temperature of 30 ?C, Na2CO3 concentration of 0.014 mol/L, and duration of 30 min. The precipitate was observed to have a structure similar to that of rhodochrosite (MnCO3). Thermogravimetric/ differential thermal analyses were subsequently performed in three different atmospheres (air, oxygen, and nitrogen) to select a suitable atmosphere for calcination. The experimental results indicated the formation of hausmannite (Mn3O4) with a purity of 97.5% Mn3O4, 0.42% MgO, 1.66% CaO, and 0.34% FeO. The specific surface area, particle size, Curie temperature, magnetisation, coercivity, and remanence ratio of the final product obtained via 3 h of calcination at 350 C were estimated to be 133.3 m(2)/g, < 142.2 nm, 56 K, 10.10 Am-2/kg, 0.35 T, and 0.19, respectively. The characterisation results revealed the excellent low-temperature ferromagnetic properties of the produced Mn3O4 nanoparticles.

    (2024-09-22) Gökçen, Hasan Serkan; Altıner, Mahmut; Kaya, Muammer; Top, Soner; Kursunoglu, Sait; Hussaini, Shokrullah; Ozsarac, Safak
    Bu çalışmada Gazipaşa-Aydap kompleks Zn-Pb cevher numunesinin sülfürik asit çözeltisindeki liç davranışı incelenmiştir. Öncelikle cevher örneğinin kimyasal ve mineralojik bileşimleri AAS, ICP-OES, XRF ve XRD analizleri ile belirlenmiştir. Cevherin yapısının çok karmaşık olduğu ve yüksek miktarda çinko (%16.4), kurşun (%10.6), demir (%2.6) ve az miktarda bakır (%0.2) içerdiği görülmüştür. 2 M sülfürik asit konsantrasyonu, 25 °C liç sıcaklığı, 1/10 katı/sıvı oranı ve 125 rpm çalkalama hızı parametrelerinde gerçekleştirilen liç işlemi ile %86.7 Zn, %90 Cu ve %25.2 Fe'nin liç çözeltisine alınabileceği saptanmıştır. Deneysel sonuçlar, liç sıcaklığının arttırılmasının çinko çözünmesi üzerinde yararlı bir etkisinin olmadığını ancak demir çözünmesini önemli ölçüde arttırdığını ortaya koymuştur. Genel olarak çinkonun, kısa bir liç süresi (30 dakika), düşük bir liç sıcaklığı (25 °C), nispeten düşük bir sülfürik asit konsantrasyonu (2 M) ve nispeten yüksek bir katı-sıvı oranı (2/10) kullanılarak kompleks cevherden ekstrakte edilebileceği belirlenmiştir.

    Manganzı Demir Cevherinden Manganın Çözündürülmesinde Farklı İndirgeme Maddelerinin Etkisi
    (Chamber of Mining Engineers of Turkey, 2022-06-26) Top, S.; Altiner, Mahmut; Kursunoglu, Sait
    IIn this paper, the manganese extraction from a manganiferous iron ore was investigated using reductive leaching. Various chemicals were used as a reducing agent to leach manganese selectively from the ore in the presence of sulfuric acid (H2SO4) solution. Firstly, optimum dissolution values were determined for selective manganese dissolution without using a reducing agent. As it was aimed at the selective extraction of manganese from the ore, the reductive leaching tests were conducted by adding the reducing agents under the following optimal parameters: a leaching time of 1 h, a stirring speed of 300 rpm, a temperature of 70°C, a sulfuric acid concentration of 1 M where the ore was leached with an extraction ratio of 11.54% Mn and 2.16% Fe. Manganese was dissolved with high efficiencies (up to 97.46%) from the ore by using different organic compounds (tartaric acid (C<inf>4</inf>H<inf>6</inf>O<inf>6</inf>), oxalic acid (C<inf>2</inf>H<inf>2</inf>O<inf>4</inf>), citric acid (C<inf>6</inf>H<inf>8</inf>O<inf>7</inf>), glucose (C<inf>6</inf>H<inf>12</inf>O<inf>6</inf>), sucrose (C<inf>12</inf>H<inf>22</inf>O<inf>11</inf>), and maleic acid (C<inf>4</inf>H<inf>4</inf>O<inf>4</inf>)) as the reducing agents. © 2022 Elsevier B.V., All rights reserved.

    Extraction of Lanthanum and Cerıum from a Bastnasite Ore By Direct Acidic Leaching
    (Chamber of Mining Engineers of Turkey, 2020-06-01) Kursunoglu, Sait; Top, S.; Hussaini, Shokrullah; Gokcen, H. S.; Altiner, Mahmut; Ozsarac, Safak; Kaya, Muammer
    The extraction of lanthanum (La) and cerium (Ce) from a bastnasite ore by direct acidic leaching was investigated. The effects of acid concentration and leaching temperature on the extraction of La and Ce from the ore were tested. Using nitric (NHO3), more than 85% of the La and Ce were simultaneously extracted into leach solution whereas the La and Ce dissolutions were determined as less than 85% by using sulfuric acid (H2SO4). The La dissolution exceeded 90% by using hydrochloric acid (HCl); however, the Ce dissolution remained below 85% under the following conditions: solid-to-liquid ratio of 20% (w/v), the acid concentration of 20%, leaching temperature of 25°C and leaching time of 1 h. The result revealed that HNO3 could be used as a solvent for the maximum simultaneous extraction of the La and Ce from the bastnasite ore. The leaching temperature had no crucial effect on the dissolution of La and Ce when HNO3 or HCl solutions were preferred as a solvating agent. However, the leaching temperature had a slight positive effect on the dissolutions of La and Ce when H2SO4 was used as a solvent. © 2023 Elsevier B.V., All rights reserved.

    Waste Lead-Acid Battery Recycling Technologies
    (Springer Science and Business Media Deutschland GmbH, 2023) Altiner, Mahmut; Top, S.; Kursunoglu, Sait
    The growing of collected waste lead-acid battery quantity means the growing demand for secondary lead (Pb) material for car batteries, both needed for increased cars’ production and for replacing of waste batteries for the increased number of automobiles in service. Pb recycling is critical to keep pace with growing energy storage needs. In recent years, tightening emission regulations have forced many developed country smelters to close. This has driven battery manufacturers and distributors to increasingly rely upon unregulated smelting operations in developing nations, negatively impacting the environment and human health. Therefore, finding a cleaner and more cost-efficient Pb recovery and recycling method is critical to the Pb recycling community. © 2023 Elsevier B.V., All rights reserved.

    (Taylor & Francis inc, 2020-10-12) Hussaini, Shokrullah; Ichlas, Zela Tanlega; Top, Soner; Kursunoglu, Sait; Kaya, Muammer
    Selective leaching of a mixed nickel-cobalt hydroxide precipitate was investigated using potassium permanganate as oxidant in sulfuric acid solution. 94.9% Ni, 50% Co and 0.6% Mn were dissolved under the following conditions: sulfuric acid concentration of 0.75 M, potassium permanganate of 5 g/L, temperature of 30 degrees C, leaching duration of 60 min, solid-to-liquid ratio of 1/10, and stirring speed of 400rpm. The pregnant leach solution was subjected to a solvent extraction process. 98% Co and 99% Mn were extracted at pH 4.84 with 30% (v/v) Cyanex 272, leaving essentially all nickel in the raffinate. Based on the experimental results, a flowsheet is proposed.

    Separation of Mn and Fe From a Manganiferous Iron Ore Using Horse Dung as Reductant: A Zero Waste Approach
    (Springer, 2022-01-13) Top, Soner; Altiner, Mahmut; Kursunoglu, Sait
    The separation of manganese and iron from a manganiferous iron ore using horse dung (biomass) as reductant was investigated in a sulfuric acid solution, and 99.80% Mn and 17.76% Fe were extracted into the solution under these leaching conditions: 1 M sulphuric acid concentration, 120 g/L biomass, 1/10 solid to liquid ratio, 300 rev/min stirring speed, 90 degrees C leaching temperature, and 3 h leaching time. In the first precipitation step, the iron and aluminum were first rejected from the solution at pH 5.04. Thereafter, 98.58% Mn was precipitated at pH 10 in the second step. The precipitate was identified as a pyrochroite mineral. After the leaching, the residue was subjected to a carbothermal reduction process conducted at 700 degrees C for 10 min in the presence of no extra reductant. The residue was converted to magnetite mineral, which can be easily recovered by magnetic separation. Based on the experimental results, a flowsheet has been proposed.

    Recent Progress in the Beneficiation of Iron-Manganese Ores: An Overview
    (Pleiades Publishing Ltd, 2025) Top, Soner
    Iron-manganese (Fe-Mn) ores are essential for steelmaking, ferroalloy production, and emerging energy technologies, yet their beneficiation is challenging due to the close association of Fe and Mn oxides and their overlapping physicochemical properties. This review assesses key processing strategies, including gravity separation, magnetic methods, flotation, reduction roasting, and selective reductive leaching. Physical beneficiation offers limited upgrades, being constrained by mineral liberation and ore texture. Reduction roasting with carbonaceous or hydrogen reductants exploits the different reduction stabilities of Fe and Mn oxides, creating magnetic contrasts for effective separation. Hydrometallurgical techniques based on reductive leaching also show strong potential, particularly with biomass-derived or organic reductants, achieving manganese recoveries often above 90-99%. A central focus is the use of Ellingham and Eh-pH diagrams as predictive tools for selective separation. Ellingham diagrams outline the thermodynamic stabilities of Fe and Mn oxides, guiding roasting design, while Eh-pH diagrams describe dissolution behavior under varying acidity and redox conditions, enabling leaching optimization. Integrating these frameworks with experimental evidence demonstrates how thermodynamic and electrochemical principles can improve process selectivity. No single technique universally addresses Fe-Mn beneficiation challenges; instead, hybrid flowsheets combining physical, thermal, and hydrometallurgical routes tailored to ore characteristics are most effective. Future research should prioritize low-carbon and sustainable approaches such as hydrogen roasting, bio-reductant leaching, and zero-waste systems. This review thus provides both a synthesis of current advances and a roadmap for sustainable Fe and Mn resource recovery.
