Abstract: Intensification of the Sulphide Leaching Process of Copper Concentrate in the Light of Electrochemical Research, earning his PhD in chemical sciences.He continued his scientific work as an Assistant Professor in the Department of Hydrometallurgy under Professor Witold Charewicz's mentorship.In 2016, he received his D.Sc.(habilitation) degree, specializing in chemical technology, based on his work titled Recovery of Copper and Associated Metals from Polymetallic Sulphide Copper Ores from the Legnica-Głogów Copper Belt Using Hydrometallurgical Methods.Throughout his academic career, Professor Chmielewski's research focused on the electrochemistry of metal sulphides, a foundation for mineral flotation and metal leaching.Much of his work dealt with minerals from the Legnica-Głogów Copper Belt (LGOM), and his research directly influenced technological advancements in minerals and metals extraction.Professor Chmielewski was deeply passionate about advancing hydrometallurgy, particularly for the non-ferrous and precious metals crucial to the Polish copper industry.He demonstrated that hydrometallurgical techniques could complement the energy-intensive pyrometallurgical methods used in Polish copper production.His research contributed to the search for sustainable methods of processing copper-bearing shale, a key component of LGOM deposits, through the BIOSHALE project, an international initiative funded by the European Union.One of his significant achievements was developing a hybrid flotation-hydrometallurgical method for processing copper ore, in collaboration with Professor Andrzej Łuszczkiewicz.This method, which involved chemically modifying shale products with sulfuric acid within the flotation system, greatly improved the efficiency of copper ore enrichment and reduced metal losses.This innovative approach was implemented at the Polkowice Copper Mine, substantially increasing copper yields.Additionally, it provided an industrial solution for utilizing sulfuric acid produced during copper smelting.In recent years, Professor Chmielewski led the HYDRO project under the IniTech initiative, funded by the National Centre for Research and Development (NCBiR).The project focused on hydrometallurgical processing of copper byproducts and concentrates, leading to highly efficient copper recovery alongside the recovery of associated metals such as Ag, Pb, Co, Ni, Zn, Mo, and V from poor polymetallic concentrates.His work addressed a long-standing challenge in pyrometallurgical processing-recovering valuable metals that are often lost.
