Science and technology of ecological engineering of ferrous and base metal mine tailings (e.g., magnetite tailings, bauxite residues (or red mud), Cu/Pb-Zn tailings) into functional technosols and hardpan-based soil systems for sustainable tailings rehabilitation: geo-microbial ecology, mineral bioweathering, geo-rhizosphere biology, technosol-plant relations in mined environments. Championing nature-based solutions to global mine wastes challenges.
Longbin Huang is a full professor and a Program leader in The University of Queensland, leading a research program of "Ecological Engineering in Mining" to develop naure-based methdology and technology, for assisting the world's mining industry to meet the global tailings challenge. Driven by the passion to translate leading knowledge into industry solutions, Longbin has pioneered transformative concepts and approach to tackle rehabilitation of mine wastes (e.g., tailings, acidic and metalliferous waste rocks). Recent success includes the "ecological engineering of Fe-ore tailings and bauxite residue" into soil, for overcoming the topsoil deficit challenge facing the mining industry. Scaled up field trials have been going on to deliver the much-needed technology into field operations. Long-term and multi-site based field trials have demonstrated for the first time, the field-feasibility to accelerate nature-based soil formaiton processes for developing tailings into adaptive and sustainable soil (or technosol) capable of sustaining plant community growth and development (https://www.youtube.com/watch?v=6VzfiWL-8UI&t=4s).
The program consists of a group of researchers with leading knowledge and research skills on: soil/geo-microbial ecology, environmental mineralogy, bioweathering of minerals, native plant rhizosphere (micro)biology, soil-plant relations, and environmental materials (such as biochar and environmental geopolymers). It aims to deliver transformative knowledge and practices (i.e., technologies/methdologies) in the rehabilitation of mine wastes (e.g., tailings, mineral residues, spoils, waste rocks) and mined landscapes for non-polluting and ecologically and financially sustainable outcomes.
In partnership with leading mining companies, Longbin and his team have been focusing on developing game-changing knowledge and technologies of tailings valorisation for achieving non-polluting and ecologically sustainable rehabilitation of, for example, coal mine spoils and tailings, Fe-ore tailings, bauxite residues (or red mud), and Cu/Pb-Zn tailings. Leading the global progress in bauxite rehabilitation, Longbin and his team are currently taking on field-scale research projects on bauxite residue rehabilitation technologies at alumina refineries in Queensland (QAL- and Yarwun refineries) and Northern Territory (Gove refinery).
Longbin's industry-partnered research was recognised in 2019 UQ’s Partners in Research Excellence Award (Resilient Environments) (Rio Tinto and QAL).

Dr Julius Kotir is a Senior Scientist with the Queensland Government Department of Agriculture and Fisheries and also an Adjunct Senior Fellow in the School of Agriculture and Food Sustainability. His academic and research interest is focused on understanding and managing the complex and long-term sustainability of coupled socio-economic-environmental systems. A particular interest is how to use this understanding to design decision support tools in the form of models to evaluate the impact of different options under an uncertain global future. His work takes an interdisciplinary approach, combining participatory co-design and field-based methods with systems thinking tools and system dynamics modelling to develop qualitative and quantitative simulation models that can support decision making. Julius has is currently using these tools and methods to address a wide range of complex agri-environmental problems including international and rural development issues, food security, economics of farming systems, agrifood and digital twin supply chains, climate-smart agriculture, water resources management, farmer adoption of new practices, and agribusiness policy design and analysis.

Dr Vivian Rincon is a microbiologist from Universidad de Los Andes in Colombia . She joined the University of Queensland (UQ) in 2008 as RA to work in projects related to plant-pathogen interactions and soil microbiology. She obtained a scholarship from the Grain Research and Development Corporation (GRDC) to start her PhD on the effect of tillage on soil microbial communities in wheat fields. Following her studies, she joined Queensland Alliance for Agriculture and Food Innovation (QAAFI) at UQ to work on different aspects of disease management in broadacre crops. Currently, she is a research fellow at the Centre for Horticulturals Science (CHS) working on an integrated disease management approach for the Macadamia industry.
