— The flotation process is considered one of the most important techniques to separate rare earth minerals from associate minerals and is commonly applied to the beneficiation of rare earth ores. It is worth mentioning that this separation method is used to separate minerals by exploiting the differences in their surface wettability [ 12, 24 ].

— 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. Over-grinding can waste resources and reduce recovery of brittle minerals.

Step #2 Ore Processing and Refining Next, the Rare Earth Ore is crushed and milled. Then the ore goes through a flotation process where it is mixed with water and special reagents to separate the rare earth elements from the tailings. Depending on the source of the ore, the concentrate may also undergo electrolytic refining.
