Dr. Bobić incorporated his rich experience from industry into scientific research bringing up many accomplishments in material science, including, among others, design and manufacturing of hybrid metal matrix composites (A356/SiCp/Grp) and nanocomposite materials (A356, Zn-Al/Ti, and ZA-27 matrix material); the development of improved processing routes in the casting of metallic materials reinforced with nanoceramic and graphite; synthesis of the alloys and metal matrix composites with enhanced mechanical and tribological properties, and corrosion behavior.

    Dr. Ilija Bobić was born and grew up in Bijeljina, Bosnia and Herzegovina. He moved to Belgrade (Serbia) for his undergraduate studies and enrolled at the University of Belgrade, Faculty of Technology and Metallurgy, where he received BSc, MSc and PhD degrees in metallurgical engineering. As a young metallurgical engineer, he developed a passion for casting processes and joined the Laboratory for nuclear materials ("Vinča" Institute of Nuclear Sciences). His research was primarily focused on the establishment of innovative processing routes of the thixocasting and compocasting techniques. Dr. Bobić was promoted to the scientific adviser position in 2014, at the Materials Department ("Vinča" Institute of Nuclear Sciences). During his career, Dr. Bobić has also been truly dedicated to the supervising and examination of master and doctoral theses of students not only from the Belgrade University but also from the University of Kragujevac.

    Aside from the scientific research, Dr. Bobić had a wide range of interests, most of all profound love of fine arts and music. His office always had a musical background of mellow blues, promoting many fruitful scientific discussions. Dr. Bobić was full of support and encouragement to all of us, his colleagues, collaborators, and students, over the years. His many scientific contributions, his warm personality, great knowledge and experience which he unconditionally shared with everyone who asked for his advice, as well as his infectious passion for scientific research will be greatly missed by all of us who had the privilege to know and work with him. As his colleagues, we are grateful for having a chance to learn from Dr. Bobić not only how to be better scientists but also how to respect and cultivate the value of kindness and generosity in the working environment. Dr. Bobić will always have a special place in our minds and hearts.

  • Hydrometallurgical operations and processes
    Vol 26 No 2 (2020)

    Preface

     

    Dear Colleagues,

     

    Hydrometallurgy is an important part of the extractive metal industry involved in the recovery of metals from ores, concentrates, technogenic and other secondary and urban mining sources; it plays an interesting role in the expansion of minerals processing industry. There are numerous hydrometallurgical process technologies used for recovering metals, such as leaching, solvent extraction/ion exchange, metals electro recovery and raffination; stabilization and remediation of tailings/waste.

    Modern hydrometallurgical processes to extract metals from their raw materials are faced with many issues related to both the chemistry, thermodynamics, kinetics, and engineering aspects of the processes involved. These issues include polymetallic and refractory character of ore, declining ore grade, fluctuation in mineralogy throw the deposits body; which would influence the hydrometallurgical route chosen. The above mentioned also applies to urban mining sources, which are complex, multimetal, with the content of toxic and hazardous substances, difficult to liberate and crucially not friendly in the processes of refining and obtaining commercially pure metals. The development of technologies to improve cleaner production, primary through energy efficiency, water/resources consumption and waste stabilization/remediation across the circuit is also an important factor to be considered. Therefore, there is an increasing scientific need to develop novel solutions to these existing problems, to implement solid environmentally sustainable practices in the recovery of these valuable metals.

    Papers on recent advances, and review articles, particularly concerning the fundamental mechanism of a chemical reaction and the development of novel techniques and technologies in the commercial processing of mineral resources from their primary and secondary sources, are selected for inclusion in this Special Issue on Hydrometallurgical operations and processes.

    Our guest editor Dr. Miroslav Sokić, Science advisor and Director of the Institute for Technology of Nuclear and Other Mineral Raw Materials (ITNMS). Dr. Sokic is an expert in extractive metallurgy. During his scientific work, he is active in the investigation domain of hydrometallurgical and pyrometallurgical processing of non-standard polymetallic ores, concentrates of non-ferrous, rare and secondary raw materials.
