Natural Occurrence

Neodymium is found in several minerals, including monazite and bastnaesite. Monazite is a phosphate mineral that contains rare earth elements, while bastnaesite is a carbonate mineral that also contains rare earth elements.

Both minerals are found in many countries around the world, including Brazil, China, and India.


Since neodymium is not found in its pure form, it must be extracted from the minerals that contain it. The extraction process usually involves a combination of several techniques, including ion exchange and solvent extraction.

In ion exchange, the mineral is first crushed and then treated with chemicals to separate the rare earth elements from other elements. The rare earth elements are then absorbed onto resin beads, which are washed with an acid solution to remove unwanted impurities.

The neodymium is then eluted from the resin with a strong acid solution, resulting in a purified solution of neodymium. In solvent extraction, the purified solution of neodymium is mixed with an organic solvent, which selectively extracts the neodymium from the solution.

The neodymium-rich organic phase is then treated with an acid solution, which separates the neodymium from the organic solvent. The neodymium is then obtained in a purified form, which is suitable for further processing.

Uses of Neodymium


One of the most important applications of neodymium is in the creation of powerful magnets. Neodymium magnets are the strongest permanent magnets available, with a magnetic strength up to 30 times stronger than regular magnets.

They are commonly used in various applications that require strong magnetic fields, including loudspeakers, power motor generators, and computer hard drives.

Glass Coloring

Neodymium is also used in the coloration of glass. When added to glass, neodymium produces a delicate shade that ranges from pale violet to light gray.

This effect is due to the absorption of certain wavelengths of light by the neodymium ions in the glass. The color is particularly sensitive to lighting conditions, and it can change from violet to blue depending on the lighting.
