The sustainable supply of critical raw materials such as the rare earth elements (SEE) is of strategic importance to secure Germany as a business location. The joint development of resource-efficient processing technologies with resource-rich countries such as Vietnam promotes the environmentally friendly development of deposits and strengthens new raw material partnerships.

The joint project NAMXE aims to quantitatively investigate the mineralogy and microstructure of the SEE-containing ores of the Nam Xe deposits using the latest methods and to develop suitable processing strategies to enable the production of marketable SE concentrates. A new geometallurgical deposit model enables the precise determination of the SEE-containing minerals and their spatial distribution. The research project helps to minimize the economic as well as the ecological risks when processing the special ore from Nam Xe.
