Description
При действии сернистого газа на водную суспензию пиролюзита образуетс на р ду с сульфатом марганца значительное количество дитионата марганца по уравнени м:Under the action of sulfur dioxide on the aqueous suspension of pyrolusite, a significant amount of manganese dithionate is formed over a series of manganese sulphate according to the equations:
MnO2 + SO, MnSOi .... (1) МпОз + 2S6, МпЗгОб . . (2)MnO2 + SO, MnSOi .... (1) MnO3 + 2S6, Mn3yOb. . (2)
Предлагаемый авторами способ получени сернокислого марганца из природного пиролюзита и сернистого газа заключаетс в том, что предварительно измельченный пиролюзит обрабатываетс раствором серной кислоты в количестве не ниже 10% от требуемого по теории количества H2SO4 дл перевода МпОз в сульфат марганца.The method proposed by the authors for the production of manganese sulphate from natural pyrolusite and sulfur dioxide is that pre-crushed pyrolusite is treated with a solution of sulfuric acid in an amount not lower than 10% of the required amount of H2SO4 to convert MnO3 to manganese sulfate.
Полученна суспензи подвергаетс действию SO2, причем реакци между пиролюзитом и SOj полностью протекает по приведенному уравнению (1).The resulting suspension is subjected to the action of SO2, and the reaction between pyrolusite and SOj proceeds completely according to the above equation (1).
Образование дитионата марганца при этом совершенно устран етс и вс заданна серна кислота регенерируетс по уравнениюThe formation of manganese dithionate is completely eliminated and all given sulfuric acid is regenerated by the equation
МпОз + S02 + H,SO,i MnSO4 + HgSOiMnOz + S02 + H, SO, i MnSO4 + HgSOi
Реакци между SOa и МпОз в присутствии серной кислоты протекаетThe reaction between SOa and MnOz in the presence of sulfuric acid proceeds
как на холоду, так и при нагревании.both in cold and when heated.
В слабо кислой среде реакци с образованием сернокислого марганца протекает при температуре 70-80°. В более концентрированном растворе HoSO4 реакци протекает без дополнительного подогрева за счет теплоты реакции.In a weakly acidic medium, the reaction with the formation of manganese sulphate occurs at a temperature of 70-80 °. In a more concentrated solution of HoSO4, the reaction proceeds without additional heating due to the heat of reaction.
Полученный раствор сернокислого марганца отфильтровываетс от SiO;, и прочих примесей, и MnSO может быть выделен кристаллизацией. Маточный щелок, содержащий серную кислоту, возвращаетс обратно в процесс .The resulting manganese sulphate solution is filtered off from SiO ;, and other impurities, and MnSO can be isolated by crystallization. The mother liquor containing sulfuric acid is recycled back to the process.
Дл получени сернокислого марганца по предлагаемому способу может быть применен печной газ сернокислотного производства, содержащий 7-8% SO2, или же отбросные промышленные газы, содержащие незначительный процент SO2.In order to obtain manganese sulphate according to the proposed method, furnace gas of sulfuric acid production containing 7-8% SO2 or industrial waste gases containing a small percentage of SO2 can be used.
Предмет изобретени .The subject matter of the invention.
Способ получени сернокислого марганца обработкой водной суспензии пиролюзита сернистым газом, отличающийс тем, что перед обработкойA method of producing manganese sulphate by treating an aqueous suspension of pyrolusite with sulfur dioxide, characterized in that prior to treatment
сернистым газом водную суспензию пиролюзита подкисл ют серной кислотой , примен емой в количестве,the sulfuric acid aqueous solution of pyrolusite is acidified with sulfuric acid, used in an amount
не меньше 10% от теоретически потребного дл перевода МпОз в сульфат марганца.not less than 10% of the theoretically required for the conversion of MnO3 to manganese sulfate.
