This project aims to systematically investigate a proof-of-concept engineering process for transforming mine waste into value. The research will develop and employ state-of-the-art tools to advance our knowledge of efficiently sequestering carbon dioxide using ultramafic nickel mine tailings, while also enabling the extraction of critical metals—particularly nickel—and the production of value-added products, such as high-purity magnesium carbonate hydrate and silica. Successful outcomes from this research will provide benefits for mitigating global warming, supplying critical metals for renewable energy technologies, and facilitating the transition of Australia's mining industry towards sustainability.

该项目旨在系统地研究将矿物废物转化为价值的概念验证工程过程。这项研究将开发和员工最先进的工具，以促进我们使用超镁铁质镍矿尾矿有效隔离二氧化碳的知识，同时还可以提取关键金属（尤其是镍含量），以及产生增值产品，例如高硫化镁含碳酸盐水合物和碳酸盐盐和硅胶。这项研究的成功结果将为减轻全球变暖，为可再生能源技术提供关键金属以及支持澳大利亚采矿业向可持续性的过渡提供好处。
