Dotychczas techniczny siarczan manganawy otrzymuje sie z dwutlenku manganu, zwlaszcza kopalnego (piroluzytu (braunsztynu), przerabiajac go na sole manganawe prziez prazenie z kwasem siarkowym, przy czym proces ten przebiega we¬ dlug nastepujacego ischematu reakcji: Mn02+2H2S04- W procesie tym uzyskuje sie silnie spieczona, twarda mase, która nastepnie trzeba rozdrabniac, aby uzyskac techniczny siarczan manganawy nadajacy sie do dalszej przeróbki. Poza tym masa ta wykazuje zmienna zawartosc M11SO4 zaleznie od czystosci uzytego surowca.Sposób wedlug wynalazku polega na tym, ze dwutlenek manganu i odpowiednia ilosc kwasu *) Wlasciciel patentu oswiadczyl, ze twórcami wynalazku sa iinz.

AND; FsIsl-.rrinZBCzypDspcritei Ludowej Published on January 30, 1956 PATENT DESCRIPTION AcrO ^ C No. 38359 Spółdzielnia Pracy "Hydrochemia" *) Warsaw, Patent Polska The method of obtaining iganawego from December 7, 1956 1954 The subject of the invention is a method of obtaining manganese sulphate. Until now, technical manganous sulphate is obtained from manganese dioxide, especially fossil (pyrolusite (braunstein), transforming it into manganese salts by roasting with sulfuric acid, and the process takes place in The length of the following reaction scheme is: MnO2 + 2H2SO4- This process produces a strongly sintered, hard mass, which must then be crushed to obtain technical manganese sulphate suitable for further processing. The method according to the invention consists in the fact that manganese dioxide and a suitable amount of acid *) Owner of the pa Tent stated that the inventors of the invention are iinz. Jerzy Skotnicki and engineer Jeremiasz Jeszka. - MnSO4 + 2H2O + SO2 + O2 'sulfur is mixed with worthless incinerable vegetable waste, such as sawdust, peat flour, vegetable dust, etc., and then mixed with prase. The obtained product is a slightly sintered, easily disintegrating manganese sulphate, which does not require grinding before further processing. The method according to the invention makes it possible to reduce the consumption of sulfuric acid by about 40% and to avoid the comminuting activity of the obtained product. PL
