Manganese ore: deposits, mining. Reserves of manganese ores …
To date, manganese ore has been found in 56 countries. Most of the deposits are in Africa (about 2/3). Total reserves of manganese ores in the world, according to theoretical calculations, are 21 billion tons (5 billion confirmed). Over 90% of these are stratiform deposits - deposits associated with sedimentary rocks.

Involvement of the Domestic Manganese Ores in Production
One of the most important parameters of manganese ores and concentrates is the phosphorus-to-manganese ratio (P/Mn), which must be ≤0.003. The domestic manganese-containing raw materials should be subjected to dephosphorization for melting standard manganese ferroalloys with the required phosphorus content.

Manganese
Manganese comprises about 1000 ppm (0.1%) of the Earth's crust, the 12th most abundant of the crust's elements. Soil contains 7–9000 ppm of manganese with an average of 440 ppm. The atmosphere contains 0.01 μg/m . Manganese occurs principally as pyrolusite (MnO2), braunite (Mn Mn 6)(SiO12), psilomelane (Ba,H2O)2Mn5O10, and to a lesser extent as rhodochrosite (MnCO3).
