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.

In the paper are shown the history, processing and applications of hematite. Hematite is an oxide of iron having the composition Fe2O3. Pure hematite, also called "red ore" contains 70% Fe.
A laboratory experiment was carried out to extract iron from oolitic iron ore by a deep reduction and magnetic separation technique. The raw coal with fixed carbon of 66.54% was used as the reductant. The iron was successfully extracted from the oolitic iron ore which otherwise is nearly impossible to be separated due to its extremely fine …
Iron is extracted in a large container called a blast furnace from its ore, hematite. Modern blast furnaces produce approximately 10,000 tonnes of iron per day.
This paper mainly highlights the formation of magnetite ore (Fe 3 O 4) by reduction of hematite iron ore (Fe 2 O ). Here, Fe and Fe 3 O 4 are magnetic, while FeO and Fe 2 O 3 are non-magnetic in nature. 2. MATERIALS AND METHODOLOGY EMPLOYED IN THE STUDY 2.1. Materials. A sample of low-grade hematite iron ore …
The reduction equipment for coal-based reduction test was a self-designed one-way heating furnace.

Ores of this type were formed extensively in Precambrian iron formations by leaching of silica, which commonly constituted in excess of 50 % of the rock. Oxidation changed iron carbonate, silicate minerals, and magnetite to hematite or limonite. The potential iron ore known to exist in an area is called iron ore resource.
