SOURCES OF IRON
Iron is the fourth most abundant element, by mass, in the Earth’s crust. The core of the Earth is thought to be largely composed of iron with nickel and sulfur. The most common iron-containing ore is haematite, but iron is found widely distributed in other minerals such as magnetite and taconite.
WHAT IS IRON LUMPS USED FOR
Iron lumps, also known as lump ore, are used in the production of steel and other metals:
-
Steelmaking
Iron lumps are a key component of the blast furnace ironmaking process, making up 5–25% of the ferrous burden.
-
Foundry processes
Iron lumps are used to improve the quality and strength of cast iron products.
-
Metal alloys
Iron lumps are a raw material used to produce metal alloys.
-
Recycling
Iron lumps can be used in recycling processes to produce lower-grade steel products.
Iron ore is the primary source of iron for the world’s steel and iron industries. Almost all iron ore is used in steelmaking, which is essential for a strong industrial base.
