Introduction In 2011, many industrialized countries were facing a rareearth crisis. For the first time in history, the demand for these elements was higher than the supply and the rareearth metal prices dramatically increased, some of them by a factor of 20. 1 This issue was due to three different reasons. First, China had a monopoly on the rareearth market at that time and supplied ...
Mining has advanced primarily through the use of two strategies: pyrometallurgy and hydrometallurgy. Both have been used successfully to extract valuable metals from ore deposits. These strategies, without a doubt, harm the environment. Furthermore, due to decades of excessive mining, there has been a global decline in highgrade ores. This has resulted in a decrease in valuable metal supply ...

Overview. The rare earth elements (REEs) are comprised of the lanthanide elements plus scandium and yttrium, which have similar physical properties and are often found in the same ores and deposits. Specifically, REEs include the light REEs (LREEs) such as lanthanum, cerium, praseodymium, neodymium, samarium, europium, and the heavy REEs (HREEs ...
After screening, the particles will be further reduced to less than 20 mm to separate rare earth minerals and gangue minerals. Step 2 Grinding. The screened rare earth ore enters a ball mill for dry grinding, improving mineral powder fineness and uniformity. Overgrinding can waste resources and reduce recovery of brittle minerals.
