Master thesis (2012 - 2015):

“Water/rock interaction in grinding and its geochemical impacts in flotation: Escondida porphyry case”. This project was developed in a joint effort between the Advance Laboratory for Geostatistical Supercomputing (ALGES) from University of Chile and the Geomet area of “Minera Escondida”. The main objective was modelling physicochemical reactions ocurring in the surface of minerals and understanding how they could affect flotation performance.

Not happy with the application of the current methodologies to link Geology and the Processing of rocks, and with the desire to increase knowledge in Processing, in 2015 Pia applied for a PhD position at SMI-JKMRC in a comminution project.

PhD Project “Studying the relationship between texture-mineralogy of rock and its fundamental breakage properties”.

The experience and previous works have demonstrated that the characteristics of rock imposed by its formation conditions clearly influences the response of different ore types in the comminution stage. Understanding and being able to predict breakage using rock characteristics could be a novel contribution to improving circuits performance, modelling and design stages. Nevertheless, until now, mineralogy by its own is not able to explain all the variability indicating that other features of the rock should be considered. The texture appears as a key feature to enhance the relationship between geology and comminution response.

With this job, Pia wants to build a methodology to relate quantitative textural measurements with intrinsically breakage properties of the rock, using single impact small-scale test and characterisation techniques to feed core-logging stage upwards.
