Raw materials

worldsteel expects that global end-of-life scrap availability will reach about 600 Mt in 2030 and 900 Mt in 2050, a growth of more than 500 Mt in one of our main steelmaking raw materials in the next 30 years. The steelmaking process is able to remove most impurities that may be present in scrap steel. Hence 'downcycling' of steel scrap ...

Making iron & steel

Before iron ore can be used, oxygen must be removed from it. Known as 'reducing', this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace …

What Raw Materials Do Auto Manufacturers Use?

Steel is produced from iron ore and is traditionally widely used in auto manufacturing. On average, 900 kilograms of steel is used in every car. Steel is used to construct a car's chassis and body ...

The first step in this process is crushing and grinding the ore to a fine powder. This powdered ore is then subjected to a process called magnetic separation, where magnets are used to separate the iron particles from other minerals present in the ore. This helps in purifying the iron ore and increasing its iron content.

Uses Of Iron Ore

Iron ore is a mineral or rock that contains a high amount of iron (Fe) minerals, typically in the form of oxides or hydroxides.These minerals can be economically extracted to produce iron, which is a metallic element used in the manufacturing of a wide variety of products, including construction materials, transportation equipment, and consumer goods.
