Manganese ore production has continually increased since the beginning
of the century, passing from one million tons in 1900 to five million tons in
1950 and reaching over 25 million tons in the mid-70's. Between 1981 and 1998
production fluctuated between 20 and 24 million tons, representing a yearly
average of 8 to 9 million tons of manganese content. Between 1940 and 1998
approximately 350 million tons of manganese contained in ore were mined.
Today's world manganese ore production is shared by a few countries:
Australia, Brazil, Gabon and South Africa; and to a lesser extent Ghana, India,
Mexico, Ukraine, CIS and China.
This figure shows the evolution in recent years of manganese ore
production and the market shares of the main producers.
