This project aims to understand how pyrochlore, the major ore mineral of the critical metal niobium, forms in Earth’s crust. Niobium is exclusively mined from carbonatite magma bodies in Brazil and Canada, despite proven Australian resources. It is used in high strength steel alloys in the construction and transport industries. Expected research outcomes include understanding how pyrochlore forms in carbonatites, development of exploration tools to locate niobium ore bodies which are unexposed at the surface, and investigation of environmentally and economically sustainable technologies for metallurgical extraction of niobium from ore. The research is intended to benefit Australia’s critical metals exploration and mining industries.

该项目的目的是了解关键金属niobium的主要矿石矿物pyrochlore如何形成 地壳。 Niobium专门从巴西和加拿大的碳酸盐岩岩浆机构开采，目的地被证明 澳大利亚资源。它用于建筑和运输行业的高强度钢合金。预期的 研究成果包括了解碳酸盐岩中如何形成碳酸盐，开发勘探工具 定位表面出乎意料的niobium矿体，并在环境和 从经济上可持续的技术，用于从矿石中提取甲壳的甲壳虫。该研究的目的是 使澳大利亚关键的金属勘探和采矿行业受益。
