Iron ore was won by drilling and blasting (Figure 7.1).As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as "dogger") allowing mine drivages to be self-supporting. However, he states …
The process of iron ore mining. Mining iron ore is a physically and chemically demanding process that takes place in remote locations around the world. The process begins with exploration, which can be done through surface or underground methods. Once a deposit is discovered, mining can begin. Open-pit mining.

Over 300 minerals contain iron but five minerals are the primary sources of iron ore. They are (i) magnetite (Fe3O4), (ii) hematite (Fe2O3), (iii) goethite (Fe2O3.H2O), (iv) siderite (FeCO3), and (v) pyrite (FeS2). The first three are of major importance because of their occurrence in large economically minable deposits.

The efficiency of iron ore mining plays a pivotal role in advancing both low-carbon transition and green recovery initiatives. A key focus in these endeavors is the imperative to improve iron ore mining efficiency, emphasizing the reduction of waste and environmental impact (Tang et al., 2023). In the context of a low-carbon transition ...
For iron ore this involves crushing the ore and then concentrating it in different ways, for example by milling, flotation or magnetic separation. At some sites the ore is processed further and pelletised for use in direct reduced iron (DRI) steelmaking. In the processing stage, the mined material is transformed into usable raw material.
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.
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.
