From 18 to 20 October, the fourth edition of the largest European mining event known as Mining and Minerals Hall (MMH) was held at the Seville Congress and Exhibition Centre (FIBES). During these days, professionals and companies from the mining industry from all over the world met. A BrineRIS booth was part of the event, which was represented by María José Jurado from CSIC. During the event, very valuable interactions and connections were generated with other participants. The objective of putting on the table the issue of recovery of metals through deep groundwater was a success on this occasion.
