Wynalazek niniejszy dotyczy sposobu umozliwiajacego otrzymanie z siarczanu cynkowego tlenku cynkowego w postaci bryl, W mysl wynalazku niniejszego siarcza¬ nowi cynkowemu i siarczanowi metalu w stanie surowym pozwala sie reagowac w ilosciach odpowiednich w ten sposób, iz siarczan cynkowy ulega calkowitej reduk¬ cji na tlenek cynkowy.Mozna równiez na siarczan cynkowy dzialac mieszanina siarczków w stanie su¬ rowym lub tez mieszanina siarczków suro¬ wych i siarczków prazonych lub wreszcie mieszanina siarczków surowych i wegla.Skoro do reakcji z siarczanem cynko¬ wym stosuje sie blende, natenczas reakcje te mozna przedstawic w postaci równania nastepujacego: 3 Zn SO4 + ZnS = 4 ZnO -f 4 S02 Reakcje mozna przeprowadzic w apa¬ racie aglomeracyjnym o dmuchu ssanym lub wdmuchiwanym, jak np, w aparatach Dwight Lloyd, Huntigton, Heberlein, Gre- enawalt i t. d.Siarczan cynku mozna stosowac w po¬ staci bezwodnych krysztalów lub tez w po¬ staci roztworu; w celu nadania mu zwarto¬ sci i zapewnienia mu dostepu powietrza mozna go zmieszac z odpowiednia iloscia blendy uprzednio wyprazonej lub tez pod¬ dac go uprzedniej aglomeracji.Siarka zawarta w blendzie surowej spa¬ lajac sie dostarcza niezbedne do reakcji cieplo.Korzystne jest do masy dodanie takze pewnej ilosci topników, np, zuzla, w celu ulatwienia aglomeracji.Blende mozna zastapic calkowicie lub czesciowo pirytem.Siarke pirytu mozna zastapic weglem.Przyklad I. 500 kg siarczanu cynkowe¬ go miesza sie z 1000 kg masy prazonej (blendy lub aglomeratu otrzymanego u- przednio) i z 500 kg blendy surowej. Mie¬ szanine te ewentualnie sie zwilza i umie¬ szcza w aparacie aglomeracyjnym, w któ¬ rym przebiega reakcja, o której mowa po¬ wyzej .Zapomoca sposobu powyzszego cala za¬ wartosc S w masie mozna zmniejszyc do 1% i mniej i otrzymac produkt dokladnie aglomerowany. PLThe present invention relates to a process which makes it possible to obtain a solid zinc oxide from zinc sulphate. In the context of the present invention, the zinc sulphate and the metal sulphate can be reacted in the raw state in sufficient amounts, in such a way that the zinc sulphate is completely reduced to zinc oxide. The zinc sulphate can also be treated with a mixture of crude sulphides or a mixture of crude sulphides and calcined sulphides, or finally a mixture of crude sulphides and carbon. Since the reaction with zinc sulphate is blended, these reactions can be presented in The following equation forms: 3 Zn SO4 + ZnS = 4 ZnO -f 4 SO2 The reactions can be carried out in a suction or blown agglomeration apparatus, such as Dwight Lloyd, Huntigton, Heberlein, Gre-enawalt and td Zinc sulphate apparatus to be used in the form of anhydrous crystals or also in the form of a solution; In order to give it compactness and to provide it with air, it can be mixed with an appropriate amount of previously calcined blend or it may be agglomerated beforehand. The sulfur contained in the raw blend as it coalesces provides the heat necessary for the reaction. also a certain amount of fluxes, e.g. slag, in order to facilitate agglomeration. Blende can be replaced completely or partially with pyrite. Pyrite grinders can be replaced with carbon. Example I. 500 kg of zinc sulphate is mixed with 1000 kg of roasted mass (blends or agglomerates obtained from - front) and with 500 kg of raw blende. This mixture is possibly wetted and placed in the agglomeration apparatus in which the reaction described above takes place. By the above method, the total S content by weight can be reduced to 1% or less and the product obtained is exactly agglomerated. PL
