Recovery of dense minerals as derivative in the exploitation of the alluvial terraces of the miño river

Times the main objective of this work is to define an industrial protocol to recover dense minerals present in the alluvial quaternary terraces of the Miño River (NW Spain), rich in a fine-grained and high-density material identified as black sands. The recovery and sale of these sands implies the c...
