We hope you enjoyed watching Treasure Hunters: Scientists Searching for Alternatives to Rare Earths.
Ready for more?
Because of the scarcity of rare earth deposits, the sky-rocketing prices on the international commodity market and the environmental problems associated with mining and processing, scientists around the world are looking for new, better ways to source these minerals. We follow researchers as they drill for new deposits in Europe and Australia, we see how they try and find new, more environmentally friendly ways of processing the materials, we discover how they try and recycle them out of old mobile phones and computers – and we reveal how physicists and chemists are working on ground-breaking new materials that could soon replace rare earths completely – a fascinating glimpse at cutting-edge research that could make our green technologies of the future even greener.
