The worldwide demand for REEs, that are important for inexperienced vitality applied sciences, has surged in recent times.
Regardless of being comparatively plentiful, these parts are sometimes troublesome to mine attributable to their tendency to happen in small concentrations or in complicated mixtures with different minerals. Surprising discoveries of REE-enriched rocks have been made in iron mines in locations like Sweden and Chile, situated on extinct iron-rich volcanoes with giant IOA deposits.
Michael Anenburg, an experimental petrologist at Australian Nationwide College and coauthor of the examine, famous that the presence of uncommon earth parts is commonly missed in such mines.
“In lots of instances, we discover REEs or different metals accidentally,” he stated. Whereas these mines primarily extract iron oxide, additional investigation might reveal untapped REE reserves.
Presently, China dominates the worldwide marketplace for uncommon earths, accounting for 70% of mine output and 89% of refining.
