Conference Object Citation - Scopus: 3Study of Certain Parameters in Laboratory-Scale Smelting of Sivrihisar Laterite Ores of Turkey(Minerals, Metals and Materials Society, 2012) Keskinkilic,E.; Pournaderi,S.; Geveci,A.; Topkaya,Y.A.Conventional ferronickel smelting has five main steps: Drying, calcination, prereduction, smelting and refining. 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: 1A Study on the Characterization of Nickel Laterites of Central Anatolia(Minerals, Metals and Materials Society, 2016) Keskinkilic,E.; Pournaderi,S.; Geveci,A.; Topkaya,Y.A.There are mainly three commercial nickel laterites in Turkey: Gordes, Caldag and Sivrihisar. The first two appear in Western Anatolia. The third one, Sivrihisar (Yunusemre) laterites have been found in the first decade of the millennium, in the Central Anatolia region of Turkey. Since then, mining facilities have been continued in Yunusemre. Calcination, prereduction and smelting of Sivrihisar laterites have been extensively studied and published. In the current work, some results of the studies related to characterization of Sivrihisar laterites will be presented.
