Overview

Liguang Wang obtained his PhD from Virginia Tech in USA. He joined UQ as a lecturer of Chemical and Metallurgical Engineering in 2006.

Research:

His current research projects include coal cleaning, mineral beneficiation, froth flotation, and gas hydrates (crystalline substance in which gas molecules such as CH4 and CO2 are trapped in a lattice of water molecules) important to energy recovery and greenhouse gas mitigation. His research program is supported by Australian Research Council, Australian Coal Association Research Program, and industrial companies.

Available Projects

  • The objective of this project is to develop a novel and effective beneficiation process to upgrade an iron ore, increase utilisation of existing iron resources, and reduce costs and adverse impacts in processing of the ores.

  • Separation of ultrafine coal particles from clay and water during a cleaning operation has been a long-term problem that the industry has faced. This project will develop advanced solid-solid and solid-liquid separation technologies, aiming to achieve high combustible recovery and low product moisture at low cost.

  • Natural gas hydrate (ice that burns) occurs abundantly in nature and is a potential source of clean energy. Formation of gas hydrates can be utilised as an alternative technology for gas separation, gas storage and transportation, and water desalination. Inhibition of gas hydrates is a challenging task in oil and gas industry. This project employs state-of-the-art tools to investigate gas hydrate formation and develop advanced methods to utilise and manage gas hydrates.
