Dr Hong Peng is an Amplify Research Fellow after being an Advance Queensland Research Fellow (Early-career, 2016-2019) and Postdoc(2014-2015) at Rio Tinto Bauxite and Alumina Technology Centre at the University of Queensland (UQ) within the School of Chemical Engineering . He gained a Bachelor’s degree in Minerals Engineering and a Master’s degree in Microbiology at Central South University, China followed by a PhD degree in Chemical Engineering at UQ. Before joining UQ Hong had experience as a chemical engineer in industry working for Its technology centre and Olympic Dam at BHP Billiton.


Hong's research focuses on the fundamental aspects of mineral processing, interfacial colloid science, leaching kinetics and precipitation reactions as well as molecular dynamics simulation. These projects are of interest to the nanobubbles, mine tailings, zeolite, clay minerals, base metals and alumina refining industries.
