It is the complexity of the purification process in itself that makes the product rare. In the same meticulous and precise way that we extract a flower’s precious essential oil to extract the most concentrated and powerful benefit, we must succeed in performing extremely precise and elaborate procedures to extract the purest material from rare- earth elements.

To date, the only tried and tested industrial technology for purifying rare-earth elements is liquid-liquid extraction. There are two types of liquid-liquid extraction: one that uses hydrochloric acid and one that uses nitric acid.

With robust know-how and industrial experience like no other in the world, the Carester experts are the only players in the sector able to master both methods and guarantee their industrial performance. This allows them to offer clients the most suitable option for their needs and their environment.

The company’s mission is to preserve these unparalleled and irreplaceable skills, perpetuating them and constantly improving them to better respect our planet.
