W procesie elektrolizy, olów znajdujacy sie w roztworze osiada na katodzie wraz z podstawowym metalem co powoduje jego zanieczyszczenie.Dotychczas w celu usuniecia olowiu z roztworu, a tym samym poprawienia czystosci metalu katodowego, na przyklad cynku, kadmu i miedzi wprowadza sie do elektrolitu czyste sole weglanu strontu lub weglanu baru co znacznie podwyzsza koszt produkcji.Zachodzila zatem potrzeba opracowania taniego i skutecznego sposobu oczyszczania roztworów siarczano¬ wych od olowiu i poprawienie przez to czystosci metalu katodowego.Postawione zadanie rozwiazuje sposób oczyszczania roztworów siarczanowych od olowiu wedlug wyna¬ lazku przez zastosowanie dodatku do elektrolitu preparatu skladajacego sie z zwiazków strontu i manganu.Preparat ten otrzymuje sie w nastepujacy sposób: koncentrat strontowy zawierajacy okolo 95% SrS04 poddaje sie trawieniu 10%-towym roztworem weglanu sodu w lugownikach z mieszadlem mechanicznym. Po uplywie 3—4 godzin mieszania do alkalicznej zawiesiny wprowadza sie nasycony roztwór nadmanganianu potasu w ilosci . 1—10 g/dcm3, a nastepnie nasycony roztwór siarczanu manganowego w ilosci potrzebnej do zredukowania nad¬ manganianu do dwutlenku manganu. Zawiesine filtruje sie, otrzymany osad stosuje sie jako preparat do oczysz¬ czania roztworów do olowiu. Tak otrzymany preparat sklada sie z ziarenek siarczanu strontu, powierzchnia których otoczona jest weglanem strontu, oraz z aktywnego dwutlenku manganu o rozwinietej powierzchni.Wprowadzenie tego preparatu do roztworu siarczanowego zawierajacego jony olowiu powoduje wspólstracanie siarczanu olowiu z solami strontu oraz adsorbcje jonów olowiu dwutlenkiem manganu. Preparat wprowadza sie do oczyszczaczy lub bezposrednio do elektrolizerów w postaci zawiesiny wodnej. Dosc stosowanego preparatu zalezna jest od stezenia olowiu w roztworze. Na przyklad do roztworu stosowanego przy elektrolitycznym2 75 303 otrzymywaniu cynku, który to roztwór zawiera olów w ilosci od 1 do 6 mg/dm3 wprowadzono 100 do 400 gramów preparatu na 1 m3 roztworu przy czym otrzymano cynk katodowy o czystosci 99,990 do 99,997% Zn.W porównaniu z dotychczas stosowanymi dodatkami SrC03 i BaC03 preparat wedlug wynalazku jest znacznie tanszy, bardzo aktywny i skuteczniejszy w dzialaniu a jego sposób otrzymywania jest prosty pod wzgledem aparaturowym i technologicznym.

In the electrolysis process, the lead in the solution settles on cathode together with the base metal, which causes its contamination. Previously, to remove lead from the solution and thus improve the purity of the cathode metal, for example zinc, cadmium and copper, pure strontium carbonate or barium carbonate salts to the electrolyte, which significantly increases the cost of production. Therefore, there was a need to develop a cheap and effective method of purifying sulphate solutions from lead and thus improving the purity of the cathode metal. The presented task solves the method of purifying sulphate solutions from lead according to the invention. The preparation of strontium and manganese to the electrolyte additive. This preparation is obtained as follows: a strontium concentrate containing about 95% SrSO4 is digested with a 10% sodium carbonate solution in skimmers with a mechanical agitator. After 3 to 4 hours of stirring, an amount of saturated potassium permanganate solution is added to the alkaline suspension. 1-10 g / dm.sup.3, followed by a saturated manganese sulfate solution in an amount needed to reduce the permanganate to manganese dioxide. The suspension is filtered and the precipitate obtained is used as a preparation for purification of lead solutions. The preparation obtained in this way consists of strontium sulphate grains, the surface of which is surrounded by strontium carbonate, and active manganese dioxide with a developed surface. Introducing this preparation into a sulphate solution containing lead ions causes the co-formation of lead sulphate with strontium salts and adsorption of the lead ions with manganese dioxide. The preparation is introduced into purifiers or directly to electrolysers in the form of an aqueous suspension. The amount of the preparation used depends on the concentration of lead in the solution. For example, into a solution used in the electrowinning of zinc, the solution containing lead in an amount of 1 to 6 mg / dm3, 100 to 400 grams of the formulation were added per m3 of solution, the cathodic zinc being obtained with a purity of 99.990 to 99.997% Zn. Compared to the SrCO 3 and BaCO 3 additives used so far, the preparation according to the invention is much cheaper, very active and more effective in operation, and its preparation method is simple in terms of equipment and technology.
