Paulina joined CODES in June 2018 to carry out her PhD project investigating the geological controls on mineral fractionation in porphyry copper deposits. Paulina’s project will focus on several world-class porphyry copper systems, including Los Bronces, Chile, to identify the mineralogical and textural controls on ore breakage and mineral fractionation. The outcomes of the project will include enhanced tools for predicting amenability to mineral fractionation in porphyry copper deposits to enhance understanding of the amenability of ore domains to grade by size fractionation.
