Unpublished paper, 'On some new and simple methods of detecting manganese in natural and artificial compounds and of obtaining its combinations for economical or other uses' by Edmund Davy

Description

Davy outlines the growing importance of manganese since its discovery, and its extensive distribution in nature. Manganese is chiefly found combined with oxygen, but its oxides are commonly mixed with those of iron, and though different methods of separating them have been recommended, yet no very simple or unobjectionable test for manganese seems to be known. Two methods for detecting manganese are recommended: firstly, the pure hydrated fixed alkalies, potash and soda, and especially potash, secondly, sulphur. Davy describes these methods.
