Geological Occurrence of Rare Earth Elements

Rare earth elements are found in various geological formations around the world. The most significant deposits are often associated with alkaline igneous rocks (carbonatites and syenites) and in sedimentary environments where ancient heavy mineral sands have accumulated. Ionic clay deposits, particularly in southern China, are also important sources, as they allow for relatively easier extraction through chemical processes rather than traditional hard-rock mining. Scotland and other parts of the UK possess a geological history that includes igneous activity and sedimentary basins where rare earth mineralization might occur. Exploration efforts typically involve detailed geophysical surveys, geochemical sampling, and drilling to assess the potential economic viability of any discovered deposits. The presence of economically viable concentrations of REEs is the primary prerequisite for establishing a mining operation.

The Mining and Extraction Process

Rare earth mining typically begins with the extraction of ore from the ground, either through open-pit or underground mining methods, depending on the deposit’s characteristics. Once extracted, the ore undergoes a series of physical and chemical processing steps. Beneficiation processes, such as crushing, grinding, and flotation, are used to concentrate the rare earth minerals. This concentrated ore then undergoes hydrometallurgical processing, which involves leaching the rare earths from the minerals using strong acids or bases. This leaching step separates the rare earth elements from other elements in the ore. The resulting pregnant leach solution contains a mixture of all rare earth elements. The most complex and costly stage is the separation of individual rare earth elements from each other. This is typically achieved through solvent extraction, a process involving multiple stages of chemical treatments that selectively extract each element. Finally, the separated rare earth oxides are converted into metals, alloys, or compounds, depending on the end-use requirements. Ensuring environmental safety and efficient resource utilization throughout this complex chain is paramount for rare earth mining companies.
