IMIDRO Projects from Exploration

to Exploitation of Rare Earth Elements in Iran

The “Rare Earth Elements Project” was launched in July 2014 with the aim of identifying the potential capabilities and resources and indigenizing the production technology of these elements in light of the development standpoints of the Iranian Mines & Mining Industries Development & Renovation Organization (IMIDRO) in the mine industry and approval of IMIDRO managing director. The executive activities of the project are being carried out in two fields: 


Exploration of rare earth elements was carried out in an area of 24000 sq. km in central Iran. As a result, two promising zones with a total area of about 900 sq. km region in east of Bafq (Yazd Province) has the highest reserves of rare earth elements in the area under exploration.

Meanwhile, identification operations in Sangan region (in Khorasan Razavi Province) confirmed nine promising mining areas and at present exploration plan of these nine areas has been put on the agenda of “Rare Earth Elements Project”.

With respect to the above mentioned studies, it seems that in Iran the rare earth elements ore bodies also contains iron and phosphate minerals as well as radioactive elements and once the total rare earth elements are extracted in the processing studies, the concentrate of REEs oxide would gain double value added. 

Mineral processing studies

The rare earth elements extraction project was studies at laboratory scale in central Iran Zone in 2016 at the Iran Mineral Processing Research Center (IMPRC) by using the IMIDRO research sources and in cooperation with Indian company possessing the relevant technical know- how.

Consequently, As a result of research and study at laboratory scale, the concentrate of REEs oxide and mish metal bullion comprising four rare earth elements of cerium (Cr), lanthanum (La), neodymium (Nd) and praseodymium (Pr) could successfully produced at IMPRC on February 28, 2016.
