Rosie Blannin is a geologist turned geometallurgist from the UK. She graduated from Imperial College London with a BSc Geology in 2016. Following this, she undertook the EMerald Erasmus Mundus Masters, a program focused on characterisation, processing and modelling in georesources engineering, and graduated in 2018. During this time, she studied at Université de Liège (Belgium), École Nationale Supérieure de Géologie in Nancy (France) and Luleå University of Technology (Sweden). Rosie then completed her Master’s thesis at the Helmholtz Institute Freiberg for Resource Technology and Technische Universität Bergakademie Freiberg (Germany), where she worked on a geometallurgical study of the copper and gold deportment of the Bolcana porphyry system.
As part of SULTAN, Rosie is working at the Helmholtz Institute Freiberg for Resource Technology. Her research focuses on the geometallurgical characterisation of sulfidic Cu-Zn-Pb tailings deposits from the Freiberg region. This entails studying the composition of the materials, and the distribution of valuable elements (such as copper, zinc and lead), critical elements (such as indium, germanium and gallium) and pollutants (such as arsenic and cadmium). Using these results, an internationally accepted reporting mineral resources and reserves standard will be applied, and a 3D model of the tailings deposit will be built. The possible beneficiation routes of the material will be assessed, and a 3D geometallurgical resource potential model of the tailings deposit will be built, by integrating the research of the other SULTAN ESRs.
On a beautiful sunny day, I went on a bike ride around some of the old mine working and mining waste deposits near Freiberg. Over twenty kilometers later, and after many (too many) hills, I arrived home somewhat tired, but excited to share what I learnt.
