Video: Swedish rare earth discovery calls attention to mining’s effects on Sámi reindeer herders

By Lisa McDonald / February 22, 2023

In January 2023, Swedish state-owned mining company LKAB announced that it had identified more than 1 million tonnes of rare earth oxides near the town of Kiruna in northern Sweden. Though mining this deposit may reduce reliance on China for rare earths, the impacts of a new mine on Kiruna residents and the indigenous Sámi people cannot be overlooked.

A ‘fin’tastic development: One-step process turns fish waste into functionalized carbon nano-onions

By Lisa McDonald / November 29, 2022

Carbon nano-onions are a newer carbon nanostructure with great potential in application, but synthesizing these materials conventionally requires high temperatures, expensive feedstock, or corrosive environments. Researchers at Nagoya Institute of Technology used a one-step microwave pyrolysis process to turn fish scales into carbon nano-onions with highly crystalline and functionalized structures.

Video: US mining companies lay plans for domestic rare earth processing facilities

By Lisa McDonald / June 22, 2022

Mining rare earth ores is only the first step in securing the rare earths supply chain. These ores must undergo refining processes, and China controls nearly all of the world’s rare earth processing facilities. Two U.S. mining companies, MP Materials and USA Rare Earth, plan to open domestic rare earth processing facilities within the next year.
