    Use of Colemanite in Ferronickel Smelting
    (Technical Faculty, Bor-serbia, 2019) Keskinkilic, E.; Pournaderi, S.; Geveci, A.; Topkaya, Y. A.
    Use of colemanite in metal-slag systems aims primarily to decrease the viscosity of slag and, therefore, achieve better metal-slag separation. Enhanced metal-slag separation is helpful to decrease the number of suspended metal/alloy droplets in slag, i.e. the physical losses. In the literature, successful use of colemanite was reported both in steelmaking and copper matte smelting processes. Ferronickel smelting slags contain nickel in the range of 0.1-0.2% and correspondingly, metal-slag distribution ratio values of nickel are reported even above 200. On the contrary, nickel recoveries are hard to exceed 95%. This can be mostly attributed to the physical losses of nickel due to very high slag volume in ferronickel smelters; for 1 ton of ferronickel, 10-15 tonnes of slag are generated regardless of the type of the laterite, which contains significant quantity of ,gangue components. The authors thought that use of colemanite could be a solution to decrease physical losses. Therefore, the use of colemanite in ferronickel smelting was investigated in the present work. Laboratory-scale smelting experiments were conducted using calcined and prereduced laterites in a vertical tube furnace under different gas atmospheres. The amount of colemanite added was in the range of 0 - 2.5% of the total charge. The experiments were also performed using ferronickel and slag samples obtained from a ferronickel smelter.

    Study 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.

    Production 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.

    Smelting Studies for Recovery of Iron From Red Mud
    (Springer international Publishing Ag, 2019) Keskinkilic, Ender; Pournaderi, Saeid; Geveci, Ahmet; Topkaya, Yavuz A.
    Red mud can be regarded as a by-product of aluminium 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. The authors have recently 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 recovery of iron and pyrometallurgical methods (smelting and solid-state reduction) will be performed. Nonferrous metals will then be selectively leached in the second step. In the extent of the present work, a literature review relevant to the smelting studies for recovery of iron from red mud was presented.
