Photograph byCurrently, the primary method for leaching rare earth ores is through in situ leaching. This approach involves contact between clay minerals and liquids, which can lead to the potential swelling of clay minerals with water, triggering natural disasters such as landslides.

Review on the Development and Utilization of Ionic Rare Earth Ore
The results show that when ammonium bicarbonate is used as an impurity removal agent, at the optimal pH value of 5.4, the removal rate of aluminum ion can reach 91.03 ± 0.1% and the removal rate of iron ion can reach 92.53 ± 0.2%, but the loss rate of rare earth is as high as 23.27 ± 1.3%.A Norwegian study has found a "substantial" amount metals and minerals ranging from copper to rare earth metals on the seabed of its extended continental shelf, authorities said on Friday in theirNorway finds 'substantial' mineral resources on its seabed

Rare Earth Element Deposits: Sources, and Exploration
Rare earth elements (REE) include the lanthanide series (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) plus Sc and Y. All these metals occur together in different types of REE deposits such as carbonatites, alkali syenites and monaziterich placers, and are found in more than 250 minerals in the Earth’s crust. The Rare earth elements (REE) are indispensable for industries such as magnetic, phosphorus, metal alloys, catalysts, ceramics, glass, polishing and defense systems due to their unique physical and chemical properties. Currently, China is the largest supplier in the world, accounting for production of more than 95% of the world’s rare Minerals Free Full-Text Descriptive Process Mineralogy to

The electrical resistances of the rare earth metals are between 25 and 131 micro-ohm-cm (μΩ-cm), which fall in the middle of the electrical resistance values of the metallic elements. Most trivalent rare earth metals have room temperature values from about 60 to 90 μΩ-cm.In August 2022, SRC announced that it produced the first rare earth metal ingots in Canadian history at its under construction Rare Earth Processing Facility using metal smelting technology.
