Rui Sousa, born in Matosinhos (Porto), holds a PhD degree in Mining and Geo-Environmental Engineering by the Faculty of Engineering of the University of Porto, completed in 2020. He developed his PhD thesis in Mining Engineering, in the speciality of Mineral Processing, studying the efficiency of mineral separations, funded by the Portuguese national funding agency for science, research and technology (FCT). During his master thesis on the Almina, Minas do Alentejo Sa mineral processing plant, he studied the Froth Flotation of Cu/Zn Massive Sulfides. He also worked for a project between National Laboratory of Energy and Geology (LNEG) and the company Beralt Tin and Wolfram owner of Panasqueira Mine, studying the viability of fine tailings reprocessing. Then, he started his research career at CERENA – Center for Natural Resources and Environment, working in the SUSMIN project studying alternative gold leaching methods. In 2016, he joined LNEG to work in the European H2020 FAME Project, in which several mineral processing methods were applied to various reference ores. He contributed for the development of a continuous pilot plant, aiming the production of lepidolite concentrates by froth flotation. He has 6 publications as first author an 2 publication as co-author in specialized cientific journals. In addition to the research activities, he is Invited Professor at the Mining Department in the Faculty of Engineering of the University of Porto.
