The Conversion Kinetics of Tincal to Boric Acid in Nitric Acid Solutions
Mehmet, Tunc; Hasan, Irem; Muhtar, M. Kocakerim; Çopur, Mehmet; Ozkan, Kucuk (Jihad Daneshgahi, 2020)Pure borax and various boron compounds are produced from the solutions in which tincal is dissolved with various reagents. Economically important boron compounds such as boric acid, borax, boric oxide, and refined hydrated ... -
Determination of Optimal Conditions for Retention of Sulfur Dioxide by Waste Ulexite Ore in an Aqueous Medium
Çopur, Mehmet; Karagoz, Ozlem; Kocakerim, M. Muhtar (Taylor & Francis Inc, 2017)The main aim of this study was to remove sulfur dioxide (SO2), which is one of the most significant air pollutants emitted from thermal power stations, using waste ulexite ore, which cannot be recycled industrially and ... -
Determination of the Optimum Conditions for Copper Leaching from Chalcopyrite Concentrate Ore Using Taguchi Method
Çopur, Mehmet; Kizilca, Meltem; Kocakerim, M. Muhtar (Taylor & Francis Inc, 2015)The optimum conditions for the extraction of copper from chalcopyrite concentrate into SO2-saturated water were evaluated using the Taguchi optimization method. High level copper recovery was obtained in an environmentally ... -

Kizilca, Meltem; Çopur, Mehmet (Taylor & Francis Inc, 2016)The kinetics of the thermal decomposition of chalcopyrite concentrate was investigated by means of thermal analysis techniques, Thermogravimetry/Derivative thermogravimetry (TG/DTG) under ambient air conditions in the ... -
Kinetic analysis of retention of SO2 using waste ulexite ore in an aqueous medium
Karagoz, Ozlem; Çopur, Mehmet; Kocakerim, M. Muhtar (Elsevier Science Bv, 2018)This study was carried out under atmospheric pressure and examined the kinetics of retention of SO2, a toxic gas, by waste ulexite ore (WUO) from a boron concentration plant, as well as the kinetics of passing B2O3 content ... -
Kinetic Investigation of Reaction Between Colemanite Ore and Methanol
Kizilca, Meltem; Çopur, Mehmet (Taylor & Francis Inc, 2015)In the field of industry, it is very important that boron compounds are produced from boron ores. The aim of this study was to investigate the dissolution kinetics with carbon dioxide of colemanite in methanol medium in a ... -
Kolemanitten borik asit üretim prosesinin optimizasyonu
Özekmekci, Mehtap (Bursa Teknik Üniversitesi, 2015)Kolemanitten borik asit üretiminde en önemli sorun, kolemanit cevheri içerisindeki yan minerallerin reaksiyon ortamında bozunarak safsızlık oluşturmasıdır. Özellikle yüksek çözünürlüklü safsızlıkların çözelti içerisinde ... -
Removal of boron from industrial wastewater using PVP/PVDF blend membrane and GO/PVP/PVDF hybrid membrane by pervaporation
Özekmekçi, Mehtap; Ünlü, Derya; Çopur, Mehmet (Springer, 2021)Removal of boron from water is a significant issue worldwide. Boron levels in waters containing high concentrations should be kept under control. Boron removal from the industrial wastewater released from Eti Mine Boron ... -
Synthesis of CaCO3 and trimethyl borate by reaction of ulexite and methanol in the presence of CO2
Özekmekçi, Mehtap; Çopur, Mehmet (Elsevier Sci Ltd, 2020)Developing CO2 capture and use of technologies to reduce anthropogenic emissions can be part of the solution against climate change. The purpose of this study is to develop a novel method to synthesize CaCO3 and trimethyl ... -
Thermal dehydration of colemanite: kinetics and mechanism determined using the master plots method
Kizilca, Meltem; Çopur, Mehmet (Taylor & Francis Ltd, 2017)Dehydration kinetics of colemanite ore were explored using thermogravimetric analysis techniques (thermogravimetry (TG)/derivative thermogravimetry (DTG)) in the range of 0-1000 degrees C at heating rates of 2, 5, 10 and ...
