Mamatwan type ore is rich in carbonates and has a high Mn/Fe ratio [8]. This is partly because Braunite I, the major component of Mamatwan type ore has considerably less iron as opposed to the higher iron content in the predominant Braunite II mineral in the Wessels type ore. Consequently, Wessels type ore has a lower Mn/Fe ratio.

Standard (or high carbon) ferromanganese, which is to manganese what pig iron is to iron, is a very commonly used alloy. It contains more than 76% of manganese and about 7% carbon, and can be produced either in the blast furnace or in the electric furnace. Production world-wide was about 3.3 million mt in 2009.
