Iron ore is a rock or mineral from which metallic iron can be extracted economically. It constitutes 5% of the earth's crust. Viable forms of ore contain between 25% and 60% iron. Ore greater than 60% iron is known as natural ore or direct shipping ore, meaning it can be fed directly into iron-making blast furnaces.
Karara comprises a large-scale, long-life magnetite orebody amenable to bulk mining and processing. Magnetite ore has lower iron content (34-36% Fe) than hematite ore (58-64% Fe). It must be upgraded by a complex ore treatment process (beneficiation) to produce a high-grade (+65% Fe) concentrate for steelmaking.

How steel is made. First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The ore-based process uses a blast furnace or smelter and the scrap-based process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster.
The chart starts with the raw materials like iron ore, coke, and lime being melted in a blast furnace to produce molten iron. Molten iron is then processed in a basic oxygen furnace where it is converted into steel by adding scrap metal and alloys. The final stage on the chart shows the casting process where steel is formed into various shapes ...

Other wastes may include small quantities of oil and grease spilled during extraction. Mine water usually contain dissolved or suspended constituents similar to those found in the ...
Now, first of all, pure iron is rarely available (except if one or two meteorites crash). It has to be derived from iron ore that occurs near the surface when mining. Then the iron derived after a long processing in the blast furnace is handed over to the iron and steel industry to make a huge amount of useful materials.

Iron ore is generally sourced from open pits on the planet's surface and typically requires only crushing before it is ready for the smelter. Like most mining, It all starts with a bang. Iron ore and its containing rock are blasted loose with high-explosives, making the ore accessible to machinery and small enough to be transported to the plant.
4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, low-capacity mines have rapidly disappeared.
