Cleaner Rare Earth Separation Using Water and Manganese Oxide Channels

A solid-state "atomic channel" for separating rare earth elements

We developed a new method to separate rare earth elements using layered manganese oxide and water, avoiding toxic solvents. By engineering channels that match ion sizes and applying an electric current with magnesium, we achieved high purity levels. This approach offers a sustainable alternative to current industrial processes, potentially reshaping where and how rare earths are processed globally.
