  • How To Make Filtered Tailings Feasible E Amp Mj

    Dewatering to create thickened tailings paste or filter cakes for dry stacking removes residual process water from the tailings making it less risky and bulky to store. It allows process water to be returned to the concentrator for reuse helping mines drive down their operating costs and it opens up multiple options for tailings storage including backfill and dry stacking.
