FIELD: metallurgy.
SUBSTANCE: proposed method comprises decomposing wastes in electrolyte solution containing sulphuric acid and hydrogen dioxide. Note here that redox potential varies from initial potential of thallic amalgam of -0.35 V to that of mercury of +0.69 V to produce pure mercury and saturated electrolyte. Note here that saturated electrolyte is in equilibrium with univalent thallium sulphate precipitate that is extracted by filtration and used as finished high-purity chemical reagent.
EFFECT: high process rate, better ecology.
