Ferro Manganese

MANGANESE ALLOYS

Manganese is the twelfth most abundant metal found within the Earth's crust and derives its name from the Latin word Magnes which means Magnet. It is the fourth most used metal in terms of quantity behind iron, aluminium and copper. It was first used in the steel industry in Ancient Greece, the presence of manganese in the iron ore is most likely the reason that the weapons made by the Spartans were superior to their enemies. It was first isolated and recognised as an element in 1771 by a Swedish chemist called Scheele.

USES OF MANGANESE

Approximately 90% of all manganese consumed worldwide goes into the steel industry as an alloying element, and because of its relatively low price and technical benefits it has no real substitute. Apart from its uses in industry, trace amounts of manganese are very important to good health. It makes bones strong but flexible and it aids the body in absorbing Vitamin B12. It also acts as an important activator for the body to use enzymes. Manganese also has important uses in aluminium as an alloying element. It is a versatile addition to copper alloys and its largest non-metal application is in the form of portable dry batteries. It also has chemical applications and is used as a ceramic and brick colourant.

PROPERTIES OF MANGANESE

Widespread use of manganese in steel making began in the UK and France at the beginning of the 19th Century. At the time it was noted that manganese increased the hardness of iron without a reduction in its malleability or toughness. In modern steelmaking manganese is added in the form of manganese alloys because of its sulphur fixing, deoxidising and alloying properties. Nearly all steels contain some manganese, in proportions that vary from 0.05% to as high as 12%. There are numerous grades of steel each requiring a different amount of manganese. The average consumption of manganese is approximately 7-10kgs of manganese per ton of steel.

PRODUCTION OF MANGANESE ALLOYS

Production of manganese ferro alloys is dominated by China, accounting for nearly half of worldwide production from a combination of domestic low grade manganese ores and imported high grade ores. Total worldwide production of manganese alloys peaked in 2008 at approximately 15 million tons, mostly as Silico Manganese and Ferro Manganese, with a number of higher grade alloys produced in lower volumes making up the difference

Available Grades:

1.     High Carbon 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 world’s largest producer.

2.     Low Carbon Ferro Manganese:

When liquid Silico Manganese is reacted with Manganese Ore or a high MnO rich slag, the silicon is oxidised increasing the Mn content of the alloy without an increase in the carbon content. This method is commonly used in South Africa to produce grades of refined (Medium and Low Carbon) Ferro Manganese with Mn 75%-80% and higher with varying carbon contents from 0.1% to 2%. The price of the alloys increases as the carbon content is reduced and unlike standard Ferro Manganese is usually sold per unit of manganese contained.
