Humphry Davy
Magnesium/Discoverers
A pure, but tiny, amount of the metal was isolated in 1808 by Humphry Davy by the electrolysis of magnesium oxide. However, it was the French scientist, Antoine-Alexandre-Brutus Bussy who made a sizeable amount of the metal in 1831 by reacting magnesium chloride with potassium, and he then studied its properties.
How is manganese mined?
The Manganese Mining Process
Most manganese mining occurs in open pits. Although there are processes in place to mine manganese nodules in the ocean floor, they cannot complete with land-based mining production. Once the ore is mined, it’s transferred to a processing plant for electrolytic processing or smelting.

History and Uses: Proposed to be an element by Carl Wilhelm Scheele in 1774, manganese was discovered by Johan Gottlieb Gahn, a Swedish chemist, by heating the mineral pyrolusite (MnO2) in the presence of charcoal later that year.
Who Discovered Iron?
The first person to explain the various types of iron was René Antoine Ferchault de Réaumur who wrote a book on the subject in 1722. This explained how steel, wrought iron, and cast iron, were to be distinguished by the amount of charcoal (carbon) they contained.
Where is manganese found in Kenya?
Kenya: A Natural Outlook
Manganese deposit occurrences are within Kilifi district along the coast, Samburu and Moyale Districts in the Rift Valley and in parts of Isiolo in Eastern Province. Production of this mineral has commenced albeit in a small scale.
Why do they mine manganese?
One of its primary uses is as a component in ferromagnetic alloys. The importance of Manganese exploded with the development of modern steelmaking technology in the 1860s. As an alloy, it decreases the brittleness of steel and imparts strength.
