Conference Object Citation - WoS: 2Citation - Scopus: 2A Study on Recovery of Iron from Red Mud by Solid State Reduction Followed by Magnetic Separation(Springer international Publishing Ag, 2020) Eray, Said; Keskinkilic, Ender; Varol, Mustafa; Topkaya, Yavuz A.; Geveci, AhmetRed mud is a waste material of the Bayer process for alumina production from bauxite ore. Red mud is generally pumped to disposal in an artificial pond which is accompanied by great land occupation and environmental issues. Many researches in different fields have been carried out to evaluate the red mud. Of these, researches on recovering valuable metals from red mud are the most successful. In this study, recovery of iron, which is the most abundant metal in red mud, was investigated. A red mud sample with 34% Fe2O3 was used. Solid state carbothermic reduction followed by wet magnetic separation was performed to recover iron. Reduction was carried out at temperatures 1000-1200 degrees C. Reduced samples were ground and subjected to wet magnetic separation. The effect of reduction temperature and grinding time were investigated on the metallization of iron and the iron content of the final concentrate.Conference Object Citation - Scopus: 4Calcination Behavior of Sivrihisar Laterite Ores of Turkey(Minerals, Metals and Materials Society, 2011) Keskinkilic,E.; Pournaderi,S.; Geveci,A.; Topkaya,Y.A.This study investigated calcination behavior of one of the Turkish laterite deposits, which was recently found in Sivrihisar region. Representative limonitic laterite samples (1.26% Ni) taken from Yunusemre Karasivritepe and Kucuksivritepe location were first subjected to drying. Removal of chemically bound water and other volatiles were then studied, in detail. In the calcination experiments, temperature and time were the main experimental variables. Thermal treatment was conducted at the specific temperatures in 250 °C-800 °C range. The weight losses due to elimination of chemically bound water and other volatiles were reported to be approximately 10 per cent of the weight of the ore. For the particle size used in the current work, 700 °C and 40 minutes were determined to be the optimum calcination temperature and time, respectively.Conference Object Calcination Behavior of Sivrihisar Laterite Ores of Turkey(John Wiley & Sons, 2011) Keskinkilic, Ender; Pournaderi, Saeid; Geveci, Ahmet; Topkaya, Yavuz A.This study investigated calcination behavior of one of the Turkish laterite deposits, which was recently found in Sivrihisar region.

In this plant, roughly speaking, at least ninety percent of sulfur in hot metal is eliminated before basic oxygen steelmaking. In the conventional process, stable sulfide-making additives of various kinds and forms are introduced to the hot metal present in torpedo cars or more commonly in ladles. Together with desulfurization reactions, a slag rich in sulfides is collected at the top, and it is then skimmed out. Other than hot metal treatment stage, further removal of sulfur may be accomplished in secondary steelmaking, depending primarily on suitability of metallurgical conditions in that specific vessel. In this literature work, recent experimental studies related to hot metal desulfurization are reviewed. More emphasis shall be on the works performed after the millennium and specifically in the last decade, including the ones offering new and novel methods.Conference Object Citation - WoS: 1A Statistical Analysis of Process Abnormalities in Slab Casting(Springer international Publishing Ag, 2018) Keskinkilic, EnderContinuous casting of slabs is conducted with two successive steel flows: first from ladle to tundish, then from tundish to mold. There are certain process abnormalities related to ladle, tundish and mold. For example, change of submerged entry nozzle (SEN) is the one encountered during steel flow from tundish to mold. Tundish exchange is the abnormality taking place due to replacement of processed tundish with the new one at rest. Another example is the flow of steel from ladle to tundish without a ladle shroud. In this study, a statistical analysis was conducted related to the process abnormalities in slab casters of a steel plant. Slab surface defects observed in slab yard was incorporated in this analysis.Conference Object Citation - WoS: 2Citation - Scopus: 2Solid-State Reduction Studies for Recovery of Iron From Red Mud(Springer international Publishing Ag, 2020) Keskinkilic, Ender; Pournaderi, Saeid; Geveci, Ahmet; Topkaya, Yavuz A.Red mud or bauxite residue can be regarded as a by-product of aluminum extraction process since it contains a significant amount of iron and some valuable elements. Therefore, the treatment of red mud has been a hot topic for some decades. Last year, the authors started a laboratory-scale project dealing with stepwise recovery of valuable elements from red mud of Seydisehir Aluminum Plant, Turkey. The first step is related to the recovery of iron and pyrometallurgical methods (solid-state reduction and smelting) are currently being performed. Nonferrous metals will then be selectively leached in the second step. In TMS 2019, the authors outlined the literature related to the smelting studies for iron recovery from bauxite residue. In the extent of the present work, a literature review relevant to the solid-state reduction studies for recovery of iron from red mud was presented.Conference Object Citation - Scopus: 1A Statistical Analysis of Process Abnormalities in Slab Casting(Springer International Publishing, 2018) Keskinkilic,E.Continuous casting of slabs is conducted with two successive steel flows: first from ladle to tundish, then from tundish to mold.

In the scope of the current work, smelting experiments were conducted using Sivrihisar laterite ores (1.26% Ni) of Turkey. The ore samples previously subjected to drying, calcination and prereduction stages were smelted in alumina crucibles in a laboratory-scale horizontal tube furnace under argon atmosphere. Smelting experiments were performed at 1500, 1550 and 1600°C. The amount of excess coal used in prereduction step was another variable. Sivrihisar laterite ore is a limonitic one with low MgO composition. Therefore, MgO was added to the smelting charge as a flux. The effects of experimental variables on metal Ni content and slag composition were investigated.Conference Object Citation - Scopus: 2Production of Crude Ferronickel From Sivrihisar Laterite Ores of Turkey(Minerals, Metals and Materials Society, 2013) Keskinkilic,E.; Pournaderi,S.; Geveci,A.; Topkaya,Y.A.In the current work, laboratory-scale smelting experiments were conducted using Sivrihisar laterites (1.26% Ni). The ore samples previously subjected to drying, calcination and prereduction stages were smelted in alumina crucibles in a horizontal tube furnace under argon atmosphere. For the smelting system used in the present work, 1550°C and 40 minutes were determined to be the optimum smelting temperature and time, respectively. 25% excess coal addition in prereduction stage was reported to be crucial to obtain the desired Ni content in the final product. Colemanite in calcined form has long been known as a flux used in pyrometallurgical systems such as steelmaking and copper matte-smelting. To investigate the effects of calcined colemanite addition on the ferronickel metal-slag system, calcined colemanite of 2% and 4% of the total metal and slag weight was charged as a flux and smelted under the optimum conditions described above.Conference Object Recent Studies on Use of Waste Plastics in Integrated Ironmaking(Springer International Publishing AG, 2025) Keskinkilic, EnderAround 7% of CO2 emissions are originated from the steel production. Nearly, three-quarters of the steel produced annually are obtained from the integrated route (BF-BOF). It is known that use of coke in BF results in 1700 kg CO2 emission per ton of hot metal. In relation to zero CO2 emission target, many investigations have been conducted in steelmaking industry for many years. One of them in blast furnace process can be regarded as replacing coke with certain alternatives. In this respect, substitution of coal and coke with biomass, use of coke oven gas (COG), use of pure H-2 gas, and use of waste plastics are some examples to the efforts to reduce CO2 emissions. In this paper, the studies aiming to substitute coke with waste plastics are reviewed.
