Mineral deposit Iron deposits Britannica
Manganese deposits. Manganese is very similar to iron in chemistry and in the way it is distributed and concentrated in rocks. Such is the case because manganese, like iron, has two important valence states, Mn 2+ and Mn 4+. In the +2 state, manganese forms soluble compounds and can be transported in solution.IRON AND MANGANESE. USGS,BED IRON OEES IN TENNESSEE, ALABAMA, AND GEORGIA. 283 such rocks.

Manganese Mining and Processing: Everything you Need to Know
More than 25 million tons of manganese are mined every year. 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.Manganese and Iron Ore Deposits CIMERA,Manganese and Iron Ore Deposits Champion: Prof Bertus Smith.
