Manganese possesses chemical properties that make it an ideal input into the making of alloys. It is commonly obtained through manganese ore in the form of manganese oxide (also known as pyrolusite), or through iron ores. Manganese production is thus often subsumed under iron mining.
Manganese Ore Uses: Manganese ore is used to alloy with steel to make it harder, an essential requirement when producing construction material. It also alloys well with aluminium to improve its anti corrosive tendencies, a feature that makes it ideal in the production of cans for the storage of beverages.
Manganese minerals do not occur freely in nature and most times consists of oxides, silicates, and carbonates, minerals with manganese ore includes pyrolusite (MnO2), braunite (Mn2+Mn3+6) (SiO12), psilomelane (Ba,H2O)2Mn5O10, and rhodochrosite (MnCO3).

Silicomanganese with 10–26 percent Si (the remainder is Mn, Fe, and impurities) is obtained from manganese ore, manganese slag, and quartzite and is used as a deoxidizer and alloying additive in the smelting of steel, as well as in the smelting of ferromanganese with reduced carbon content by the silicothermic process.
Manganese is a silverygray metal and is part of the group known as the transition metals. It is similar to iron. It is hard to melt, but easy to oxidize. Manganese forms chemical compounds in several oxidation states: +2, +4, and +7 are the most common.

Iron ore is the main ingredient in steel, which makes up 95 percent of the metals used in the world per year. Two billion metric tons of raw iron ore are produced in a year. The world's largest single producer of iron ore is Brazilian mining company Vale, which produces over 350 million tons of iron ore annually.
Manganese is a silverygrey metal. It has an atomic symbol of Mn, and its atomic mass is amu (atomic mass units). The atomic number of manganese is 25, which means there are 25 protons in its nucleus. Manganese is found in the transition metal section of the periodic table.

The Kisenge Manganese Mine is a surface mining operation. Initial production took place in 1951. Mine operations consist of surface workings. There is one known shaft. The mining method is open pit. The ore mined is composed of spessartite, rhodonite and pyrolusite. As of 1991 there were two known tabular shaped ore bodies of unknown dimensions.
