This project aims to advance our fundamental understanding on the geochemistry of antimony – a critical mineral resource and environmental pollutant of growing concern. This will be achieved by pioneering an innovative combination of advanced synchrotron-based tools and sophisticated isotopic approaches to unravel important interactions between antimony geochemistry and the iron cycle in soils, sediments and aquatic systems. The expected outcomes will provide novel insights into refined strategies to manipulate coupling between antimony mobility and iron cycling for improved rehabilitation of degraded landscapes, safe disposal of hazardous wastes and sustainable exploitation of Australia’s valuable antimony reserves.

该项目旨在促进我们对锑的地球化学的基本理解-锑是一种日益受到关注的关键矿产资源和环境污染物。这将通过开创先进的同步加速器工具和复杂的同位素方法的创新组合来实现，以揭示土壤，沉积物和水生系统中锑地球化学与铁循环之间的重要相互作用。预期的结果将提供新的见解完善的战略，以操纵锑的流动性和铁循环之间的耦合，以改善退化景观的恢复，危险废物的安全处置和澳大利亚宝贵的锑储量的可持续开发。
