Although the rare earths have been around since the formation of Earth, their existence did not come to light until the late 18th century.In 1787 the Swedish army lieutenant Carl Axel Arrhenius discovered a unique black mineral in a small quarry in Ytterby (a small town near Stockholm). That mineral was a mixture of rare earths, and the first …

Apron feeders are a volumetric type feeder, which means bulk density is used to determine the speed and power (torque) needed to extract a certain tonnage per hour (tph) of material.
Most rare-earth metals have a valence of three; however, that of cerium is 3.2, and europium and ytterbium are divalent. This is quite evident when the metallic radii are plotted versus atomic number.The metallic radii of the trivalent metals exhibit the normal lanthanide contraction, but a noticeable deviation occurs for cerium, where its …
Rare-earth element - Abundance, Occurrence, Reserves: As noted above, the rare earths are fairly abundant, but their availability is somewhat limited, primarily because their concentration levels in many ores are quite low (less than 5 percent by weight). An economically viable source should contain more than 5 percent rare earths, …
This infographic features data from the United States Geological Society (USGS) which reveals the countries with the largest known reserves of rare earth elements (REEs). What are Rare Earth Metals?
