Description
Неоднократно делались попытки получени активной двуокиси марганца путем хлорировани как щелочного раствора гидрата окиси марганца, так и углекислого марганца; однако при этом получалс продукт, неприменимый в элементной промышленности.Attempts have been made to obtain active manganese dioxide by chlorinating both an alkaline solution of manganese oxide hydrate and manganese carbonate; however, a product was obtained that was not applicable in the element industry.
Предлагаетс способ получени двуокиси марганца, годной в качестве депол ризатора, основанный на предварительном процессе превращени пиролюзита в браунит с последующей обработкой последнего хлором в водной среде, что ведет к достаточно полному использованию марганцевой руды.A method is proposed for producing manganese dioxide suitable as a depot, based on a preliminary process of converting pyrolusite to brown, with subsequent treatment of the latter with chlorine in an aqueous medium, which leads to a fairly complete use of manganese ore.
Предлагаемый способ в целом сводитс к следующему.The proposed method generally boils down to the following.
Природный пиролюзит подвергаетс восстановлению или термической диссо-циации, причем образуетс браунит и частично гаусманнт .Natural pyrolusite is subjected to reduction or thermal dissociation, with brownite and, in part, hausmanth being formed.
МпОа -+ МпаОд -+ МпзО4 Процесс восстановлени руды восстановительными газами; протекает при тем пературе 250° в течение часов. В результате-, этой реакции получаетс браунит с примесью гаусманита.MpOa - + MpAOD - + MpzO4 The process of ore reduction by reducing gases; proceeds at a temperature of 250 ° for hours. As a result, this reaction produces brownish with an admixture of hausmanite.
Браунит получаетс и при термической диссоциации руды, дл чего пеобходимо нагревать ее при 750 в течение трех часов или же при 1000-1050° в течение 5-10 минут. Обожженный или восстановленньп продукт размалываетс до частиц 100 мещ и подвергаетс воздействию газообразного хлора в водной среде прн Т ; Ж 1 : 3,5.Braunite is also obtained during thermal dissociation of ore, for which it is necessary to heat it at 750 for three hours or at 1000-1050 ° for 5-10 minutes. The calcined or reconstituted product is milled to a particle size of 100 mes and is exposed to chlorine gas in an aqueous medium; G 1: 3,5.
Гидрат марганца, полученный из бедных руд, сначала окисл етс до браунита на воздухе лрн 120°, а потом подвергаетс процессу хлорировани .Manganese hydrate, obtained from poor ores, is first oxidized to braunite in air of lrn 120 °, and then subjected to the chlorination process.
Температура хлорировани восстановленной руды около 75°, а обожженной при высоких температурах - 75-85°.The chlorination temperature of the reduced ore is about 75 °, and calcined at high temperatures is 75-85 °.
Весь процесс окислени продолжаетс 3-5 часов.The entire oxidation process lasts 3-5 hours.
В результате предлагаемой обработки низщих окислов марганца газообразным хлором получаетс активна двуокись марганца со свойствами, необходимыми, дл элементной промышленности.As a result of the proposed treatment of low manganese oxides with chlorine gas, active manganese dioxide with the properties necessary for the elemental industry is obtained.
Готовый продукт отмывают от ионов хлора; при этом в раствор переходит только около 15% марганца , а преобладающа часть марганца из браунпта или : аусмапнта upeiipaiuacTcst к активную двуо:кись марганца.
