Data on development of sewage treatment of zinc production from anions in experimental conditions (SO₄^2–, Cl^–) is resulted. Sewage before dump in reservoirs of fisheries and general use, as a rule, demand additional cleaning. It is offered the barium sulphide use as reagents for a sulphate-ion conclusion. Clearing of chlorides can be spent by known in zinc hydrometallurgy methods. Water is suitable for return to a water circulation sewage treatment from sulphates-ions.
