Ferro Manganese
Ferro Manganese is produced by reduction of Manganese Oxide in blast furnaces or electric furnaces. It is a very flexible process in that the slags can be reprocessed into Ferro Silico Manganese which in turn can be further refined into Medium and Low Carbon Ferro Manganese.
Ferro Manganese was invented in 1860 by Sir Henry Bessemer as a way to add Manganese during steel making with the advantage that a combination of Iron and Manganese Oxide results in a lower melting point for the alloy Ferro Manganese compared to pure Manganese Oxide.
Standard Ferro Manganese (or High Carbon Ferro Manganese) is a commonly used alloy produced by the reduction of manganese ore in the presence of carbon. Typically it contains 75% manganese and 7% carbon. Worldwide production of Ferro Manganese in 2008 was approximately 4.5 million tons, with China being the worlds largest producer.

Manganese
is used
for:
- It is the principal deoxidizing agent in steel making and an important alloying element used for the production of ordinary mild steel as well as sophisticated low and high alloy steels.
- It also has the property of controlling the effect of sulphur, which when manganese is present, forms manganese sulphide and tends to float out of the liquid steel.
- Manganese has the effect of stabilizing austenite.
- Steel with 12 to 14% Mn is fully austenitic, and is used on a large scale for its wear and abrasion-resisting characteristics
