Изобретение относитс к области производства манганата кали .This invention relates to the field of potassium manganate production.
Известен способ получени манганата кали путем сплавлени окисной марганцевой руды со щелочью (гидроокисью кали ) в среде кислородсодержащего газа.A method of producing potassium manganate is known by fusing manganese oxide ore with alkali (potassium hydroxide) in an oxygen-containing gas.
Недостатком указанного способа вл етс низка степень превращени марганца в манганат .The disadvantage of this method is the low degree of conversion of manganese to manganate.

Дл повышени степени превращени по предлагаемому способу марганцевую окисную руду, содержащую Мп+2 и Мп+, предварительно смещивают с ферромарганцем, вз тым в количестве, соответствующем превращению его в окись марганца за счет активного кислорода , содержащегос в исходной руде.In order to increase the conversion rate of the proposed method, manganese oxide ore containing Mn + 2 and Mn + is preliminarily shifted with ferromanganese, taken in an amount corresponding to its conversion into manganese oxide due to active oxygen contained in the original ore.
Степень превращени марганца в манганат достигает 807о (см. таблицу).The degree of conversion of manganese to manganate reaches 807 ° (see table).
