The final sulphate includes all four of the most economically important rare earth elements (NdPr, Dy and Tb) in economic quantities in line with the Phalaborwa mineral resource. These are known as the \"magnet rare earths\" as they are used to make the permanent magnets essential to decarbonisation via their use in electric vehicles and wind turbines.\nPhotos of the mixed rare earth sulphate can be viewed at https://www.rainbowrareearths.com/projects/gallery/\nThe mixed rare earth sulphate produced by the Phalaborwa pilot p...
