Nathaly completed a degree in Geological Engineering at the Universidad Central del Ecuador. After completing her Bachelor degree, Nathaly started work as a full time Junior geologist at the Cascabel Cu-Au porphyry in northern Ecuador. While working at Cascabel, Nathaly was involved in geological, alteration and mineralisation logging activities. She then became part of the database team, where she oversaw the analysis and interpretation of spectral data from rock, drill cores and soil samples, to develop the alteration model of Cascabel.

After Nathaly completes her Masters at the University of Tasmania, she would like to remain in the mining industry to use the knowledge acquired during her candidature. This would enable her to provide support for the industry to gain maximum value from commodities. 

  

     

 Focus area:

Predictive geometallurgical controls on grade-by-size fractionation in gold systems.

 

 

Nathaly’s masters research is focused in a phenomenon known as ‘natural deportment’ or ‘grade-by-size fractionation’. Natural grade by size deportment is the tendency for specific mineral phases to preferentially fractionate during breakage into different size fractions.

Preferential grade-by-size deportment represents a key underlying driver for Grade Engineering®, which has been demonstrated to increase the economic viability of ore systems by separation of lower grade, coarse material prior to energy intensive crushing and milling.

This project aims to evaluate the geological controls on this fractionation by understanding the role of mineralogy, texture and paragenesis in influencing rock breakage and natural fractionation at a range of scales.

This project is executed in rocks of core samples and bulk samples sourced from the Gramalote Project, located in Colombia.
