Abstract

Biography

Cathy is an experienced mineral processing engineer and geometallurgist who has been applying her extensive knowledge of geometallurgy, applied mineralogy, comminution and separation processes in geometallurgical projects and the optimisation of mineral processing operations for over 30 years. Through her career in industry, consulting and now applied research at the University of Queensland’s Sustainable Minerals Institute, Cathy has worked on a broad range of ore types and commodities including lead, zinc, copper, nickel, gold, silver, platinum minerals and iron ore. Her expert knowledge of how the mineralogy and texture of ores impact their processing behaviours spans the mining process chain from comminution, through separation to tailings disposal and smelting. Cathy enjoys sharing her knowledge with the next generation of metallurgists, including teaching applied mineralogy to undergraduate engineers, supervising postgraduate research students and delivering professional development courses on applied process mineralogy and geometallurgy to industry professionals both in person and online.
