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 Silicon 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 world’s largest producer.

We typically supply Ferro Manganese in High, Medium and Low carbon forms in lumps and powder, however, our sources manufacture all forms of ferromanganese and we can supply in any form or density.
