Thread: Manganese!

Hey

Basically I am trying to isolate manganese metal from both its chloride and carbonate.

Thing is though all the sources online give conflicting answers when I ask if I can simply displace it with Aluminium powder.

Before I waste anything - separating the manganese - is it just a simple displacement with Aluminium

on this topic does anyone know of a compiled re-activity series with all the metals so I don't run into such a frustration again

Thanks
Joshua

Never worked with manganese so answer to first part is dunno.

Reactivity series: Reactivity series - Wikipedia, the free encyclopedia

You can produce metallic manganese using aluminium via the Goldschmidt process, more commonly known as the thermite reaction.

Experimental details here:

The mangano-manganic oxide can be prepared by from the carbonate by heating.
The carbonate can be prepared from the chloride by precipitation with sodium carbonate.

Since manganese decomposes water even in the cold, I don't think that you will have success with a simple displacement reaction in aqueous solution.

Warron, you seem to be a "mine" of solid information about metals, minerals and their extraction. Do you work in this industry by any chance?

Hi exchemist. Thanks for the comment. I am a Chemical Engineer so have industrial experience, but I have had long interest in chemistry for its own sake. I was given my first chemistry book at the age of 11 ( a copy of Partington's Inorganic Chemistry) and I have been adding to the collection and browsing them for the subsequent 50 years.

From your name I take it that you have some experience in the industry too?

Chemistry degree and a career in the downstream oil industry (lubes mostly), after a short spell training as a patent agent. Retired now, though.

Re other members, they remain a mystery to me, apart from PhDemon. Some months ago we found my old tutor in physical chemistry at Oxford had been PhDemon's supervisor in his research year, and that HIS old tutor was the don whose lectures I had found the most mind-expanding as an undergraduate. Which was nice to know.
