This project aims to discover how microbes dissolve weathering-resistant phosphate minerals that contain valuable rare earth elements used widely in modern technology. This discovery would create new knowledge in the interdisciplinary fields of biogeochemistry and biohydrometallurgy, using an innovative combination of techniques in metagenomics, microbiology and mineralogy. Expected research outcomes include new, more economic and environmentally sustainable biotechnologies for recovering rare earth elements and increasing phosphorus availability in Australian mineral deposits and soils. These outcomes should benefit the mining and agricultural sectors, by decreasing Australia's dependency on overseas REE supply and the use of fertilizers.

该项目旨在发现微生物如何溶解耐候磷酸盐矿物，这些矿物含有在现代技术中广泛使用的有价值的稀土元素。这一发现将利用元基因组学、微生物学和矿物学的创新组合，在生物地球化学和生物湿法冶金等跨学科领域创造新的知识。预期的研究成果包括新的、更经济和环境可持续的生物技术，以回收稀土元素，并提高澳大利亚矿藏和土壤中磷的有效性。这些成果将减少澳大利亚对海外稀土供应和化肥使用的依赖，从而使矿业和农业部门受益。
