    Selection of an Appropriate Acid Type for the Recovery of Zinc From a Flotation Tailing by the Analytic Hierarchy Process
    (Elsevier Sci Ltd, 2021-02) Kursunoglu, Sait; Kursunoglu, Nilufer; Hussaini, Shokrullah; Kaya, Muammer
    The selection of acid type for metal dissolution from minerals is an important issue in leaching operations. Acids are used to recover valuable elements from the minerals by dissolving them in a solution. The acid must offer a high recovery at marginal cost and a low environmental effect. Many parameters can affect the acid type selection for high leaching recovery and low environmental effect and thus, the selection of an acid type is complex. In this study, based on the experimental results obtained from the bench-scale laboratory studies, the selection of acid type for the recovery of zinc from a flotation tailing was investigated using the analytic hierarchy process (AHP). The utilization of AHP was supported by the use of ExpertChoice (R) 2000 software. The outcomes demonstrated that sulfuric acid is the most desirable acid type with a ranking of 0.541, tracked by citric acid, and oxalic acid with scoring of 0.282 and 0.177, respectively. Furthermore, analyses of sensitivity were performed to examine the influence of the main criteria on the different acid type. It emerged that citric acid can be used when the environmental main criterion ascended from 7.8% to 75.3%. (C) 2020 Elsevier Ltd. All rights reserved.

    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.

    Dissolution of Mixed Zinc-Carbon and Alkaline Battery Powders in Sulphuric Acid Using Ascorbic/Oxalic Acid as a Reductant
    (Minerals, Metals and Materials Society 184 Thorn Hill Road Warrendale PA 15086, 2012-03-17) Kaya, Muammer; Kursunoglu, Sait
    The aim of this study was to investigate the effectiveness of ascorbic (C<inf>6</inf>H<inf>8</inf>O<inf>6</inf>) / oxalic (C<inf>2</inf>H <inf>2</inf>O<inf>4</inf>) acid as a reductant for the simultaneous recovery of zinc and manganese from a spent and mixed zinc-carbon and alkaline battery powder in sulphuric acid leaching. The effects of sulfuric acid concentration, ascorbic/oxalic acid dosages, reaction temperature and leaching time on the zinc and manganese dissolutions were investigated according to 2k full factorial experimental design; then, a simple optimization study was carried out for the best reductant. The optimum reductive acid leaching conditions were determined at 3 hours leaching time, 70°C leaching temperature, 0.5M sulfuric acid concentration, 13 g/L ascorbic acid dosage, 1/20 g/mL solid/liquid ratio and 200 rpm stirring speed. Under these conditions, the dissolution efficiencies were 99.9% for Zn and 99.3% for Mn. When our results were compared with the previous results, our findings were better than previous studies. In addition, the manganese dissolution kinetics was undertaken, and the activation energy was found to be 7.04 kJ/mol. Selective precipitations of Zn and Mn from acid solutions were carried out using NaOH and KOH. Using 3M NaOH as precipitating agent at room temperature and at pH 8; 95.4% of Zn and at pH 10; 93.7% of Mn were precipitated from the leaching solution. Under the same conditions, using 3 M KOH at pH 8; 91.6% of Zn and at pH 10, 96.4% of Mn were precipitated. Based on the experimental results obtained, an appropriate flow sheet was proposed to recover zinc and manganese. © 2020 Elsevier B.V., All rights reserved.

    Synergistic Effect of Organic Acid on the Dissolution of Mixed Nickel-Cobalt Hydroxide Precipitate in Sulphuric Acid Solution
    (Edp Sciences S A, 2019) Kursunoglu, Sait; Kursunoglu, Sait
    The synergistic effect of an organic acid on the dissolution of nickel and cobalt from a mixed nickel-cobalt hydroxide precipitate (MHP) in sulphuric acid solution was studied. The effects of sulphuric acid concentration, the type of organic acid, leaching time, leaching temperature and stirring speed on the dissolution of the metals were experimentally investigated. It was observed that there is no beneficial effect of leaching temperature and stirring speed on the dissolution of the metals from the used MHP product which contains 37.7% Ni, 2.1% Co and 5.6% Mn. It was found that citric acid was more effective than oxalic acid for the dissolution of nickel and manganese, whereas oxalic acid was more effective than citric acid for the dissolution of cobalt. The addition of oxalic acid into the leaching system, however, affected the dissolution of nickel negatively because nickel precipitate as nickel oxalate. Therefore, the use of citric acid as synergist for sulphuric acid leaching of MHP product is more promising. After 60 min of leaching, 90.9% Ni, 84.2% Co and 98.1% Mn were dissolved under the following conditions: 0.75 M sulphuric acid, 2 g citric acid, 1/10 solid-to-liquid ratio, 400 rpm stirring speed and 30 degrees C temperature. The experimental results demonstrate that the addition of citric acid as a synergist for sulphuric acid leaching of a MHP product provides beneficial effect for the dissolution of nickel, cobalt and manganese.

    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.

    Critical Review on Secondary Zinc Resources and Their Recycling Technologies
    (Elsevier, 2020-08) Kaya, Muammer; Hussaini, Shokrullah; Kursunoglu, Sait
    In a race to save the earth of its rapidly depleting natural resources, the use of Secondary Raw Materials (SMRs) as alternative replacements in several processes is currently intensively pursued. The valorization of SMRs is consistent with the sustainable circular economy, where resource efficiency is maximized for the benefit of both the economy and green environment. In line with this mandate, this article focuses on investigating recent studies on secondary zinc (Zn) resources and describing state-of-art Zn recycling technologies. Globally, some of the main Zn-containing secondary raw materials are mine/concentrator/smelter tailings, wastes, slags, scraps, dust, etc. Although the pyrometallurgical process has been dominant in the secondary metal recycling processes, there has been growing interest and pressure to achieve sustainable and greener recycling methods to remediate the environmental problems caused by emissions of toxic heavy metals and sulfur oxides in the traditional smelting process. In the last decades, many sustainable and environmentally friendly novel hydrometallurgical processes for Zn extraction were developed to overcome tougher legislation and meet cost competitiveness. Secondary Zn recycling focuses on the development of selective Zn-rich but Pb, Fe, As-lean recovery processes.

    Leaching of Turkish Oxidized Pb-Zn Flotation Tailings by Inorganic and Organic Acids
    (Springer International Publishing AG, 2020) Kaya, Muammer; Kursunoglu, Sait; Hussaini, Shokrullah; Gul, Erkan
    An eco-friendly approach and simultaneous recovery of metals from mine tailings is still a significant challenge. This study investigates the extraction of zinc metal from the Kayseri region oxidized lead-zinc (Pb-Zn) flotation tailings by leaching using three different inorganic acids (HNO3, HCl, and H2SO4) and six different organic acids (citric (CA), oxalic (OA), formic (FA), ascorbic (AA), malic (MA), and tartaric (TA) acids). The effects of acid type and concentration, leaching temperature and time, and solid/liquid (S/L) ratio were studied for maximum Zn dissolution and minimum Pb, Fe, and As co-dissolution at lowest temperature and leaching time. For inorganic acids at 1/10 S/L ratio, 1.0MH(2)SO(4) and HCl concentrations achieved 92% Zn + 0% Pb + 12% Fe at 40 degrees C leaching temperature and 60 min leaching time and 92% Zn + 10% Pb + 0% Fe at 80 degrees C leaching temperature and 30 min leaching time, respectively. For organic acids, at 1/10 S/L ratio and 1.0M concentration, 92% Zn + 8.3% Pb with malic acid at 80 degrees C leaching temperature and 180 min leaching time and 91% Zn + 12% Pb with citric acid at 60 degrees C leaching temperature and 180 min leaching time were achieved. 1.0 M formic acid dissolved about 83% Zn + 2.8% Pb at 80 degrees C and 180 min leaching time. More than 90% Zn dissolution can be succeeded by using either inorganic acids at 40 degrees C for 30-60 min leaching time or organic acids at 60-80 degrees C for 180 min leaching time. Oxalic acid significantly dissolved Fe and As without Zn and Pb dissolution.
