Speaker
Mr Isaac Heath
Metallurgist
Newmont
Applying modern flotation technology to improve fine particle recovery at Cadia
10:40 AM - 10:55 AMBiography
Isaac graduated in 2020 from the University of New South Wales with a dual degree in materials science and chemical engineering. He began his career as a graduate metallurgist in 2021 and since then has gained experience in gold and copper operations throughout the Central West of NSW. He was also a finalist for the NSW Mining Young Achiever of the Year award in 2022. Isaac has an interest in hydrometallurgy and enjoys the challenges of working in a production-based role. He is currently a Plant Metallurgist working in the flotation circuit at Cadia Valley Operations in NSW where he brings a practical mindset and a collaborative approach to solving complex metallurgical challenges in dynamic plant environments.
