Gravity Separation. Gravity-based procedures have been used in the processing of REE minerals for many years, especially when the REE minerals are found in alluvial or sand deposits. These procedures are applicable for REE ores that show a difference in specific gravities of the contained minerals, i.e. bastnaesite, monazite, and xenotime all ...
