The global area covered with mine waste is in the order of 100 million hectares containing several 100,000 million tonnes of mine wastes. The long-term sustainable rehabilitation of metal mine sites is inhibited by our lack of knowledge of metal resistance and uptake by Australian native plants. This project will evaluate metallophytes naturally growing on metal-rich soils, northwest Queensland, for their capabilities and revegetation potential when grown in mine wastes of the Cannington Ag-Pb-Zn mine. Outcomes will include practical, innovative methods of mine site rehabilitation that are low-cost and environmentally-friendly.

全球矿山废弃物覆盖面积约为 1 亿公顷，含有数十亿吨矿山废弃物。由于我们缺乏对金属抵抗力和澳大利亚本土植物吸收的了解，金属矿场的长期可持续恢复受到抑制。该项目将评估昆士兰州西北部富含金属的土壤上自然生长的金属植物在坎宁顿银铅锌矿的矿山废物中生长的能力和重新植被潜力。成果将包括低成本且环保的实用、创新的矿场修复方法。
