20 µm, reducing by 51% the fraction by weight smaller than 200 mesh, which reduces the volume of unusable material and increases by 3.6 times the initial permeability that allows the greatest transit of water, optimizing the amount of material needed for the construction of tailings, requiring less volume to achieve the same structural capacity, which also decreases the cost per cubic meter of compacted tailings. KEYWORDS Mine-to-tailings integration, water management, dewatering screen, tailings storage facility, sustainability, clays, sands permeability.
