Xianwen Dai joined CSIRO in 2006. He is now a senior research scientist and Precious Metals Team Leader in CSIRO Mineral Resources. His research interests include processing of gold using cyanide or thiosulfate, leaching and electrochemistry of gold, resin and carbon adsorption & elution and cyanide recovery. He has published over 40 research papers and managed a number of industrial projects. His research highlights include the development of a thiosulfate based process for treating gold gravity concentrates and a cyanide recovery process for treating cyanidation tails solutions, and technology advancement for supporting the commercialization of a CSIRO gold extraction reagent.

Peter Fraser is a Professional Engineer and holds Master’s degrees in both Mechanical Engineering and Business Administration. He started his career with the South African Chamber of Mines Research Organization and has been with Hydropower Equipment (HPE) in South Africa since 1998, where he is involved with innovation and growing market awareness of oil-free, water-hydraulic mining solutions. HPE has developed the use of high-pressure water (hydropower) to transport rock, reduce energy consumption and power mining equipment (including oil-free, water-hydraulic drills, drifters and drill rigs). Peter is a member of the SA Institution of Mechanical Engineers, the SA Institute of Tribology, and the Southern African Institute of Mining and Metallurgy.
