Hace 3 días · Green Gold: Turning E-Waste Into a Treasure Trove of Rare Earth Metals. ETH doctoral student Marie Perrin presents the new recycling approach. In her left hand, she is holding the raw material in the form of a fluorescent lamp and, in her right, the yellow reagent that can separate rare earth metals. Credit: Fabio Masero / ETH Zurich.
Hace 5 días · The first could be an important source of a number of critical metals, such as yttrium, neodymium and gadolinium, used in catalysts and magnets. The latter could be a major source of germanium and gallium, used in semiconductors, LEDs, electrical transmission components, solar panels and electric vehicle motors.

Hace 1 día · Rare earth from a newly discovered sedimentary rare earth ore (SREO) in Guizhou Province, China, was extracted through ammonium sulfate ((NH4)2SO4) activated roasting and leaching with sulfuric acid. The phase changes and reaction mechanism during the roasting process were explored through thermodynamic analysis, XRD, thermogravimetric analysis and scanning electron microscopy. When roasted at ...
