Hence, heavy rare earths Dy and Tb which have less abundance in rare earth became more important but essential. Similarly, addition of less abundant Pr to Sm–Co alloy improves alloy corrosion resistance. The Sm–Co magnet is a high Curie temperature alloy that

Heavy rare earths, permanent magnets, and renewable

Whereas light rare earths can be processed outside of China, the more troublesome heavy rare earths are handled exclusively in China. At the moment, only one facility outside of China, Rhodia's La Rochelle plant in France, could potentially isolate heavy rare earths, including dysprosium.

Lofdal Heavy Rare Earths Project Namibia Critical Metals

The first systematic exploration for rare earths over Lofdal was initiated by Namibia Rare Earths in 2008. In 2011 the Area 4 heavy rare earth deposit was discovered and since that time exploration results have demonstrated the occurrence of rare earth mineralization on a district scale (Figure 2).

Difference Between Light Rare Earth Element & Heavy Rare

Elements with atomic numbers 63 to 71 make up the heavy rare earths. Elements in that group include europium and gadolinium. Yttrium is a heavy rare earth even though its atomic number is 39. Scientists place it in the heavy group because its properties resemble those you find in the heavy rare earth

How to Separate Heavy Rare Earth Elements

Equilibrium tests showed that iminodiacetic resin has a low affinity for heavy rare earths and a high affinity for light rare earths in an EDTA media. These tests also showed that sulfonic resin has about equal affinity for heavy and light rare earths in an EDTA media. Table 2 lists the total percentage of the rare-earth pairs that re-mained

Yttrium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium are the "heavy rare earths." Although yttrium is lighter than the light rare earth elements, it is included in the heavy rare earth group because of its chemical and physical associations with heavy rare earths in

Rare Earth Metals: Heavy vs. Light Magnets MPCO

Heavy rare earth metals. Heavy rare earth metals are defined by their higher atomic weights relative to light rare earths. They are less common, and some elements within the group are facing shortages as demand outpaces supply. That typically makes them more valuable than light rare earths, though they also have smaller markets.
