Overview

Associate Professor Longbin Huang specializes in ecological engineering and rehabilitation of ferrous and base metal mine tailings (e.g., magnetite tailings, bauxite residues (or red mud), Cu/Pb-Zn tailings). He is the program leader of ecological engineering and rehabilitaiton of tailings in Sustainable Minerals Institute, leading multidisciplinary projects on Cu tailings, Pb-Zn tailings, Fe-ore tailings, bauxite residues (red mud) for sustainable rehabilitaiton. The research is expected to deliver innovative and feasible technology and methodology to rehabilitate tailings - the most costly and challenging domains at mine sites and refineries, in order to significantly improve economic and ecological sustainability of mining and minerals industries in Australia and overseas.

Research Interests

  • Hardpan technology for capping and rehabilitating sulfidic and metallic tailings
    This research aims to develop hardpan-based soil system for rehabilitating sulfidic metallic tailings domain at mine sites, for substantially improving environmental and ecological sustainability and lowering economic costs of tailings rehabilitaiton and closure.and/or hardpans.
  • Engineered pedogenesis: ecological engineering technosols in tailings for native plant rehabilitation
    This research investigates biogenic factors (e.g., extremophiles, bacteria, fungi, and roots) in bioweathering of tailings minerals and associated biogeochemical processes and to develop new technology and methodology for rehabilitating metal mine tailings. The emerging technology and methodology are expected to deliver the much needed knowledge and know-how to speed up the rehabilitation of mine tailings, such as rare earth mineral (clay-exchangeable type) tailings, magnetite/hematite iron ore tailings, coal tailings, porphyry Cu tailings, and red mud .
  • Technosol-plant relations: rhizosphere mechanisms of colonising plant species
    This investigates microbial and biochemcial mechanisms in the rhizosphere of pioneer and native keystone plant species colonising technosols eco-engineered from tailings.
  • Next generation foliar fertiliser delivery technology
    This focuses on the R&D of technology for long-lasting delivery of trace elements or micronutrients via bio-chemical engineered and modified mineral compounds.
  • Next generation intelligent fertilisers for efficient P and N supply in cropping soils
    This investigates new materials (low cost geo-minerals) and mechanisms to deliver P and N in cropping soils, which are responsive to plant needs and water availability, thus avoiding/minimising rapid release of P and N into soil matrix.
  • Ecophysiology and physiology of native metallophytes in metal mined environments and tailing-technosols
    Focuses on the understanding of rhizosphere mechanisms and metal(loid) mobilization/uptake in native metallophytes and tolerant species which are often used to revegetate pioneer plant communities. It aims to identify native plant species which can effectively phytostablize metal mine tailings and land heavily contaminated by AMD.

Research Impacts

My research aims to transform the current technology and practice and develop new technology and methodology of ecological engineering and rehabilitation of metal mine tailings, such as bauxite residues (red mud), magnetite-tailings, Cu/Pb-Zn tailings, for substantially improving economic and ecological sustainability of mining and minerals industry.
