Extraction Of Manganese From Its Ore

2 · The modern name "manganese" was derived from the 16 th century name for manganese dioxide, manganesum. The pigments from several colored manganese oxides, such as manganese dioxide, have been used by men since the Stone Age, as is the case in the Gargas cave paintings. These have been dated as 24,000 to 30,000 years old.
