In December 2023, the European Union adopted the Critical Raw Materials Act (CRMA) to secure essential resources for its energy transition and strategic sectors like aerospace and healthcare
Bioleaching is a hydrometallurgical process using microorganisms to extract metals from rocks. Even if it is slower than some other chemical leaching technologies, bioleaching offers several advantages compared to conventional metallurgical processes, such as lower energy and chemical consumption, lower CO2 footprint and lower capital and operational costs.
Blanca Perdigones reports that the University of Seville (USE) team visited the facilities of Atalaya Mining S.A. at the start of February, which allowed them to disseminate the key aspects of the RAWMINA project to the company as a potential final user.
