FIELD: process engineering.SUBSTANCE: invention relates to processing of iron-bearing wastes of nuclear industry produced in pickling of contaminated metal surfaces. Claimed process comprises the steps that follow, i.e. dissolution of contaminated surfaces by phosphoric acid, oxidation of iron ions, increasing of the solution pH, separation of settled salts from the liquid phase and thermal treatment of the mix of settled solid substances by vitrification.EFFECT: minimised volumes of liquid phase to be treated, recycling of by-products.13 cl, 1 dwg |
