Ucore Rare Metals (TSXV: UCU; US-OTC: UURAF) has completed the commissioning of its RapidSX commercial demonstration plant for separating rare earth elements (REEs), at its facility in Kingston ...

Ecological restoration of rare earth element (REE) mining areas has become a key component in the sustainable development of the ion-adsorption-type REE industry. Current studies on ecological restoration assessments are mainly based on a comparison of REE mining ranges conducted over two or more periods, therefore, the …

The Bear Lodge Project is positioned to be a major North American source of rare earth elements (REEs). The quality and quantity of the mineralization at Bear Lodge make it a world-class mining district and a dependable, long-term source for the REEs that technology demands. The Project is rich in the REEs critical to high-strength permanent ...

A small molecule that naturally serves as a binding site for metals in enzymes also proves useful for separating certain rare earth metals from each other. In a proof of concept, the process ...

The Lingbei rare earth mining area in Dingnan County in the red soil hill region was used as a case study since it is a representative ion adsorption rare earth mining area.

The process of extracting rare earth elements from ore is complex and environmentally intensive. It involves mining the ore, separating the rare earth elements through various chemical processes, and refining them into usable materials.

Electrokinetic mining (EKM) is a novel method for rare earth element (REE) mining that can achieve green and efficient recovery of REEs. However, as yet, there is no accurate model for describing the electrokinetic transport of REEs in weathering crusts, and this hinders the wider application of EKM. The conventional model fails to capture the …

Certainly, Rare Element Resources thinks it will. With plans for $400 million in infrastructure in and near the towns of Sundance and Upton, the mining company specializing in rare earth metals believes it has a rock-star project to compete with China's near monopoly on these useful substances. The deposit, nine miles northwest of …

The Mountain Pass Rare Earth Mine and Processing Facility is the only scaled site of its kind in the Western Hemisphere. The self-contained nature of its operations – with co-located mining, milling, separations, and finishing – creates significant cost advantages and mitigates operational risks.
