Ferromanganese facts for kids
Ferromanganese is a special type of metal. It is an alloy, which means it is a mix of two or more metals. This alloy is mostly made of iron and manganese. Imagine mixing iron, which is used to make steel, with manganese, a silvery-gray metal. Ferromanganese usually has about 15% manganese and 85% iron. It is also sometimes called spiegeleisen.

How is Ferromanganese Made?
Making ferromanganese involves a process called reduction. This is a chemical reaction where oxygen is removed from a substance. To make ferromanganese, a mix of iron ore and manganese ore is heated. An element like carbon is added. Carbon acts as a "reducing agent." This means it helps to take the oxygen away from the metal ores. This process leaves behind the iron and manganese metals, which then combine to form the ferromanganese alloy.
Why is Ferromanganese Important?
Ferromanganese is very important in making steel. Steel is a strong metal used in buildings, cars, and many other things. When ferromanganese is added to steel, it helps to remove unwanted oxygen and sulfur. This makes the steel stronger and less brittle. It also helps to make the steel easier to work with. Because of this, ferromanganese is often how manganese is sold for industrial use.
