e-HydroMat Lab works with (Electro)Hydrometallurgy, a new concept of hydrometalurgical process using electrochemical reactions and separations to obtain critical minerals, promoting Sustainable Mining to achieve the energy transition. We define sustainable mining as a set of mining processes and activities related to producing raw minerals from primary and secondary sources near- to-zero waste generation.
