Researchers realize selective recovery of high-value rare earth elements from waste NdFeB

Recycling high-value rare earth elements from NdFeB waste can save resources, reduce industrial waste, protect the environment and bring considerable economic benefits. However, most traditional recovery methods take a long time to process, have high acid consumption, and low selectivity.

In a study published in Separation and Purification Technology, the research group led by Prof. Yang Fan from Fujian Institute of Research on the Structure of Matter of the Chinese Academy of Sciences proposed a new integrated method for recycling permanent magnet waste by betaine hydrochloride ([Hbet]Cl) solution extraction.

The researchers first carried out leaching experiments on fully roasted magnetic clay samples, and selected [Hbet]Cl as the leaching agent.

They found that when leaching temperature was 200° Celsius, leaching time was eight hours, lixiviant [Hbet]Cl concentration was 0.2 mol/L, and solid–liquid ratio was 1:150 g/ml. They were able to get optimum leaching results of 99.81% Pr, 97.05% Nd, 95.51% Gd, 56.24% Ce and 0.20% Fe, and almost all iron oxide remained in the residue.

Exploring the Uses of Rare Earth Elements

Rare earth elements find applications in technologies ranging from high-tech devices, clean energy, and hybrid vehicles to wind power turbines, hard disk drives, and defence systems. All elements in the lanthanide series share similar chemical, magnetic, and spectroscopic properties; their role in a wide range of applications is attributed to these shared characteristics. 

The Applications of Rare Earths

The primary sources of rare earth elements are bastnaesite and monazite. In India, monazite tops the list of mineral materials for the production of rare earths. It includes many lanthanides; approximately 50–70% of them are light rare earth elements (LREE).

Here are the various uses of rare earth elements:

Cerium (Ce) is one of the most abundant rare earth elements in the Earth’s crust. It is used to polish glass items such as lenses, liquid-crystal displays and plasma-display panels. It is also used as a fuel additive in fuel material like petrol and diesel. In combination with lanthanum, it has a use as an environmentally friendly substitute of cadmium in red pigments. Mischmetal, a mix of cerium and some other rare metals, is used to keep steel clean during its production phase.

Lanthanum (La) and neodymium (Nd) find application as glass additives in optical lenses and display screens. Along with yttrium (Y), they help store elements like magnesium, aluminum, and hydrogen. They act as catalysts to minimise sulphur dioxide emissions in automobiles. Nd also finds uses in welding in heavy industries and in medical equipment like MRI scanners.

Samarium (Sm), dysprosium (Dy), praseodymium (Pr), and terbium (Tb) are utilized in electronics, electric motors and audio equipment for their magnetic properties. Pr is used as neodymium’s replacement in magnets.

Scandium (Sc) is primarily used in aluminium alloys for sports equipment. This metal is mixed in small amounts in semiconductors and halogen bulbs.

Rare earth magnets, such as neodymium-iron-boron (NdFeB), are used in anti-lock brakes in cars to prevent the wheels from locking when you brake hard. These magnets also find applications in small gadgets such as digital cameras.

Nickel metal hydride (NiMH) batteries are considered special batteries. They have a mix of rare metals, including mischmetal, and are used in laptops, camcorders, and mobile phones to power them.
