Ferromanganese crusts also contain mi- nor amounts of detrital minerals, such as quartz and feldspar. Most thick crusts (greater than about 60millimetres) also contain a phosphate mineral called carbonate fluorapatite, which is a secondary mineral that forms long after the manganese and iron oxides have precipitated from seawater.

Ferromanganese - Wikipedia
Ferromanganese is a ferroalloy with high manganese content (high-carbon ferromanganese can contain as much as 80% Mn by weight). It is made by heating a mixture of the oxides MnO 2 and Fe 2 O 3, with carbon (usually as coal and coke) in either a blast furnace or an electric arc furnace-type system, called a submerged arc furnace.The oxides undergo carbothermal …
