Description
В процессе производства активного пиролюзита образуютс отходы в виде кислых растворов сернокислого марганца.During the production of active pyrolusite, waste is generated in the form of acidic solutions of manganese sulphate.
В 1 л этих растворов содержитс от 10 до 50 г серной кислоты (счита на моногидрат) и от 250 до 300 г сернокислого марганца.1 l of these solutions contains from 10 to 50 g of sulfuric acid (counting on monohydrate) and from 250 to 300 g of manganese sulphate.
Но так как в растворах содержатс ен1е и примеси в виде сернокислых солей железа, кальци , кобальта , никел и др. элементов, выделение из этих растворов чистого сернокислого марганца представл ет значительные трудности.But since enle and impurities in the form of sulfate salts of iron, calcium, cobalt, nickel, and other elements are contained in the solutions, the isolation of pure manganese sulfate from these solutions presents considerable difficulties.
Описываемый способ позвол ет использовать сточные воды от производства активного пиролюзита дл получени сульфатного аммонийно-марганцевого микроудобрсни и отличаетс тем, что кислые растворы сернокислого марганца подвергают нейтрализации аммиаком с образованием смеси солей сульфатов марганца и аммони .The described method allows the use of wastewater from the production of active pyrolusite to produce ammonium manganese sulfate microfluidic fertilizers and is characterized in that acidic solutions of manganese sulphate are neutralized with ammonia to form a mixture of salts of manganese sulphate and ammonium.
Дл осуществлени описываемого способа сточные водЕзг от производства активного пиролюзита в виде кислых растворов сернокислого марганца заливают в мешалку, где при комнатной температуре нейтрализуют водным раствором аммиака при непрерывном перемешивании .To implement the described method, wastewater from the production of active pyrolusite in the form of acidic solutions of manganese sulphate is poured into a mixer, where it is neutralized at room temperature with an aqueous solution of ammonia with continuous stirring.
В результате получают нейтральный раствор, содержащий сульфат марганца, сульфат аммони , гидрат окиси аммони (в виде взвеси) и небольшое количество солей кальци , железа, кобальта и других.The result is a neutral solution containing manganese sulfate, ammonium sulfate, ammonium hydroxide (as a suspension) and a small amount of calcium, iron, cobalt, and others.
Нейтральный раствор уцаривают и затем прогревают до полного удалени гигроскопической и гидратной влаги, после чего сухую массу подвергают помолу на шаровой мельнице.The neutral solution is concentrated and then heated until complete removal of hygroscopic and hydrated moisture, after which the dry mass is subjected to grinding in a ball mill.
Получепный продукт содержит 10 - 15% сульфата аммони , 80-85% сульфата марганца, до 4% гидрата окиси марганца, до 1% сульфатов кальци , железа, кобальта и др. и используетс как микроудобрецие в тех случа х, когда сельскохоз йственные культуры нуждаютс в марганце.The final product contains 10-15% ammonium sulphate, 80-85% manganese sulphate, up to 4% manganese oxide hydrate, up to 1% calcium sulphate, iron, cobalt, etc., and is used as a microfertilizer in those cases when crops are in need. in manganese.
Предмет изобретени Subject invention
Способ получени сульфатного аммонийно-марганцевого микроудобрени , отличающийс тем, что, с целью введени в удобрение соединений марганца, сточные воды от производства активного пиролюзита в виде кислых растворов сернокислого марганца подвергают нейтрализации аммиаком с образованием смеси солей сульфатов мар1анца и аммони .The method of producing ammonium manganese sulfate microfertilizer, characterized in that, with the aim of introducing manganese compounds into fertilizer, wastewater from the production of active pyrolusite in the form of acidic solutions of manganese sulphate is subjected to neutralization with ammonia to form a mixture of salts of marlite and ammonium sulphates.
