For the tailings treatment process, Dasen mining has a tailings dry discharge process and a tailings re-concentration process. Dry discharge of tailings is a tailings dewatering technology independently launched by Dasen Mining and effective treatment technology for building a green mine.

In Current years, tailings dry discharge is a gradually emerging new tailings treatment process. It means the tailing pulp from the dressing plant through multi-concentration, then uses dewatering vibrating screen to treat and get low moisture, easy sediment solidify and is good for stockpiling slag. Slag can be transported to a fixed position for dry stockpiling.
