Profile:

I worked within the Work Package Froth Flotation (WP7) of the EU Project Optimore (Horizon 2020) between 2015-2017. The project was focused on increasing yield on Tungsten and Tantalum ore production by means of advanced and flexible control on crushing, milling and separation process. My main objective was to be able to model froth flotation more accurately in order to improve its process control. More information on the project can be found here: https://cordis.europa.eu/project/id/642201

Since the end of the project, I focused on my PhD, titled "Depressants in scheelite flotation: mechanism of sodium carbonate and acidified water glass and the application of process mineralogy". The thesis was submitted in January, 2020 and had three goals: 1) Summarize the state of scheelite flotation research; 2) Use R-enhanced automated mineralogy data to better undersand mineral behaviors; 3) Identify the mechanism of sodium carbonate and acidified sodium silicate in scheelite flotation.

I studied mining geology at the Institut Polytechnique de LaSalle Beauvais (France) and wrote my Master thesis on introducing mineralogical techniques in froth flotation to optimize the lab testing procedure of  Clariant Mining Solutions. I then worked for the BGR (German federal institute for geosciences and natural resources) on the subject of certification of raw materials (3Ts and gold) in the Democratic Republic of the Congo before coming to the HIF.
