Curtin University Ups Glycine Gold Leaching Rates With Permanganate Agent



Curtin University researchers say they have improved their award-winning glycine leaching technology by “significantly enhancing” the leaching rates for gold ore by using a low concentration of a strong oxidising agent known as potassium permanganate.

The Curtin team is currently working with minerals industry partner, Mining and Process Solutions Pty Ltd (MPS), to commercialise the new process.

The research, published in Hydrometallurgy and led by Professor Jacques Eksteen and Dr Elsayed Oraby both from the Western Australia School of Mines: Minerals, Energy and Chemical Engineering,
