Direct electrochemical reduction of copper sulfide in molten borax
Kartal, Levent; Timur, Servet (Springer, 2019)In this study, for the first time, direct copper production from copper sulfide was carried out via direct electrochemical reduction method using inexpensive and stable molten borax electrolyte. The effects of current ... -
Electrolytic production of Cu-Ni alloys in CaCl2-Cu2S-NiS molten salt
Kartal, Levent; Timur, Servet (Elsevier Science Bv, 2018)An alternative metal/alloy production method, known as direct electrochemical reduction (DER), was introduced for the fabrication of CuNi alloys from mixed sulfides (Cu2S, NiS) under both galvanostatic and potentiostatic ... -
A New Approach for Cu and Fe/FexB Production from Chalcopyrite by Molten Salt Electrolysis
Kartal, Levent; Daryal, Mehmet Barış; Timur, Servet (Springer, 2020)In the present study, copper (Cu) and iron boride -( FexB) were produced for the first time through molten salt electrolysis using chalcopyrite -(CuFeS2) in an oxide- based borax electrolyte. Molten salt electrolysis was ... -
A New Approach for Cu and Fe/FexB Production from Chalcopyrite by Molten Salt Electrolysis
Kartal, Levent; Daryal, M.B.; Timur, S. (Springer Science and Business Media Deutschland GmbH, 2020)Abstract: In the present study, copper (Cu) and iron boride (FexB) were produced for the first time through molten salt electrolysis using chalcopyrite (CuFeS2) in an oxide-based borax electrolyte. Molten salt electrolysis ... -
One-step electrochemical reduction of stibnite concentrate in molten borax
Kartal, Levent; Daryal, Mehmet Baris; Sireli, Gueldem Kartal; Timur, Servet (Springer, 2019)In this study, antimony production from a stibnite concentrate (Sb2S3) was performed in one step using a molten salt electrolysis method and borax as an electrolyte. Electrochemical reduction of the stibnite concentrate ... -
Optimization of sulfuric acid leaching of roasted chalcopyrite concentrate with Box-Wilson experimental design
Sonmez, Ibrahim; Sahbudak, Kemal; Kartal, Levent; Alkan, Bulent (Springer International Publishing Ag, 2020)Chalcopyrite (CuFeS2) is commonly used ore in production of copper, but leaching of this ore is very slow and inefficient due to passivation during leaching at atmospheric conditions. In this study, in order to overcome ... -
The removal of heavy metals from refinery effluents by sulfide precipitation
Kartal, Levent; Şen, Aysel; Timur, Servet (BERG FAC TECHNICAL UNIV KOSICE, 2023)This study investigated the selective precipitation of copper (Cu2+), nickel (Ni2+) and zinc (Zn2+) ions from industrial wastewater by using sodium sulfide (Na2S). The effects of pH, time and free sulfide concentration on ... -
Single step calciothermic synthesis of nickel boride particles in molten salt
Kartal, Levent (Springer, 2023)Abstract In this study, production of nickel boride (NixB) via calciothermic reduction in molten salt has been studied. Firstly, the electrochemical behaviors of CaO and NiO in CaCl2 melt were examined by cyclic voltammetry ...
