making steel from iron ore-XinHai Mineral Processing

As iron is the main component of steel it firstly needs to be made. Iron ore, lime, and coke are placed into a blast furnace and melted. The resulting liquid known as molten iron is then formed. As molten iron still contains around 4% 4.5% impurities such as carbon which in turn make the metal brittle, they need to be eradicated.

Wrought iron is quite soft and easily worked and has little structural strength. It was once used to make decorative gates and railings, but these days mild steel is normally used instead. Mild steel. Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes.

The Ironmaking Process New Zealand Steel

In each of the two melters, electricity is used to achieve the final reduction of iron oxides present in the RPCC and to liquify the iron. For the reduction, the carried over carbon (char) is used and it is very important that a constant amount is present in RPCC in order to produce quality iron in the melter. The mix of iron and oxide impurities is heated above melting temperature so that the iron and slag may be

Iron ore BHP

It takes around 1.6 tons of iron ore to produce one ton of steel. The chemical symbol for iron is 'Fe' because of its Latin name Ferrum. We use 20 times more iron (in the form of steel) than all other metals put together. Our iron ore trains are over 2.5km (264 ore cars) long, meaning it can take half an hour from one end to the other.

During the iron-making process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes (minerals, such as limestone, which are used to collect impurities). Air which is heated to about 1200°C is blown into the furnace through nozzles in the lower section. The air causes the coke to burn, producing carbon monoxide which reacts with the iron
