Manganese nitrate from batteries

In this Video I turn crude manganese dioxide I got from alkaline batteries into manganese nitrate by first reacting the crude manganese oxide with formic acid, isolating the manganese formate, turning it into manganese carbonate and reacting the latter with nitric acid to obtain manganese nitrate. Note that if a stronger acid was used to dissolve the MnO2 another purification step would have been neccessary to remove the resulting iron contamination.

the biggest source for manganese dioxide in battery form is C cell D cell and 6volt lantern battery, as you'll get the most bang for your buck. i dont think its worth it to extract from AA and AAA, cause they're so small. plus its a hassle so getting more for less work is always a plus.

Щавелевая кислота подойдет лучше. Карбонат марганца образуется сразу. И сразу добавляем азотную кислоту и потом только фильтруем.

Iron is a common impurity in manganese dioxide, so that may be the reason it's brown, you are dissolving the iron and then it precipitates out as the carbonate maybe

you tricked me, i thought i was gonna see an epik battery collection!

Und ist am Ende noch reines Mangan(II) Nitrat ausgefallen? Hatte mir überlegt einfach eine doppelte Umsetzung aus MnSO4 und Ca(NO3)2 zu machen, dann filtern und das Produkt kristallisieren zu lassen. Habe aber nicht das Gefühl, dass sich die Kristalle lohnen

Mit was für ein Löffel konntest du die Salpetersäure/mangancarbonat Mischung umrühren?

You should make more videos on how to make ammonium nitrate

[keidanmeradi]

does it have any pyrotechnic use? is it an oxidizer?

[omsingharjit]

And what is the process if i wanna use HCl ! After formation of MnCl2 how can i conver it to MnCo3 ?
Will NaCo3 double displacement methode do the job ?

[nicoschadjidemetriou]

Why my dear you don't react the Mn oxides with nitric acid?

Very cool! I'm getting into electrochemistry now too. You should check out the MysteriusBhoice channel, he does some awesome stuff, and his electrode designs might help you.
