Iron Ore Mining | Techniques | Metal Extraction
Iron ore is the unrefined substance utilized to formulate pig iron, which is one of the most important untreated materials to compose steel. 98% of the hauled out iron ore is used to produce steel. Uncontaminated iron ore is almost nameless on the exterior of the Earth apart from the combination of Fe-Ni alloys from meteorites and very atypical forms of unfathomable mantle xenoliths.

What Is Involved in Pig Iron Production? (with pictures)
Iron ore is combined with charcoal in a blast furnace to create pig iron. The process of pig iron production involves the combination of iron ore, charcoal, and an intermediary material known as a flux inside a blast furnace. As the materials combine with intense heat, much of the iron ore melts, creating a superheated, liquid form.

What Is Involved in the Processing of Iron Ore? (with pictures)
The main goal for the processing of iron ore is to take the ore extracted during the mining effort, break the ore into usable units and then purify those units before the actual smelting begins. Doing so makes it easier to produce a higher grade of iron that in turn can be used to create materials for use in everything from manufacturing lawn furniture to cookware to building materials.

The BOF process uses 30% of recycled steel, while EAF uses up to 90-100%. This is a far more sustainable option instead of mining more iron ore as a fresh ingredient in the steelmaking process. There is also an alternate steelmaking process called HIsarna ironmaking. In HIsarna, iron ore is processed immediately into hot metal.

Coal. Lime stone. The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace. Temperature raised to 1600 o F. This high temp causes the coke to burn and melt the iron.
