Eco-engineering soil from mine tailings for native plant rehabilitation. This project aims to develop integrated and low-cost eco-engineering technology to purposefully accelerate in-situ formation of soil from tailings for sustainable native plant community rehabilitation at metal mines. Soil shortages at mines cost the Australian mining industry billions of dollars in sustainable rehabilitation of tailings, and threaten the industry’s ecological and commercial sustainability. Building on recent findings of critical processes in soil formation from copper/lead–zinc tailings, this research will use key biogeochemical and rhizosphere processes in the tailing-soil to create a functional 'technosol'. This technology is intended to be used in Australian metal mines to offset the soil needed to rehabilitate tailings landforms with native plant communities.

生态工程土壤从矿山尾矿原生植物恢复。该项目旨在开发综合和低成本的生态工程技术，有目的地加速尾矿土壤的原位形成，以促进金属矿山可持续的本地植物群落恢复。矿山的土壤短缺使澳大利亚采矿业在尾矿的可持续恢复方面花费了数十亿美元，并威胁到该行业的生态和商业可持续性。建立在铜/铅锌尾矿土壤形成的关键过程的最新研究结果，本研究将使用关键的土壤地球化学和根际过程中的尾矿土壤，以创建一个功能性的“technosol”。这项技术旨在用于澳大利亚的金属矿山，以抵消恢复尾矿地貌所需的土壤与本地植物群落。
