I have compiled a list of sources for the elements that are available to the amateur chemist. Manganese will be discussed here.


Manganese is a silvery hard corrosion-vulnerable metal. It is not commonly used as an element. Ferromanganese, the form in which it is sold, is about 85% manganese and 15% iron. Manganese compounds are used in batteries, pyrotechnics and pigments.


In element form: Reduction of manganese(II) chloride produced by dissolution of manganese dioxide in hydrochloric acid should produce manganese. (If the solution is yellow not light pink then there is contamination and you will reduce iron not manganese.) Manganese steel has 10-15% manganese in it.


In compound form: Impure manganese dioxide is found in alkaline and carbon-zinc batteries. Manganese chloride can be made by dissolving purified manganese dioxide in hydrochloric acid.


Here is my sample of manganese. It is produced by magnesium reduction of a manganese chloride solution.
