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.
Direct reduction technologies offer an alternative route to ironmaking, bypassing the conventional blast furnace. Processes like the Midrex and HYL/Energiron systems utilize …

The Cloud Break iron ore mine is located in Pilbara, Western …
During this process the water content of the iron ore is released, and its structure becomes looser, which makes it easier to smelt. Finally, we break up the burnt iron ore into 2-3 cm pieces to make it easier to load the iron ore into the furnace during the smelting process (See Figure 3). Step 3. Building furnaces.
Galinheiro is the second biggest holding 563.1 million tonnes (45.4%Fe) of iron ore in proven and 410.5 million tonnes (43.8% Fe) of probable reserves. Sapecado and Galinheiro open pits have been in operation since 1948, whereas the Segredo and Joao Pereira open pits have been operational since 2003.

In an attempt to shed its reputation as an environmental polluter, the mining industry is increasingly deploying greener technologies to ensure its operations are more energy efficient and have a less degrading impact on the environment. Here is a round up of some of the best green technologies on the market. Heidi Vella July 25, 2013.
For some unknown reason, this technology lagged in the iron industry for an additional fifty years. From the time in which the first serious demands for the substitution of coal for charcoal came about, almost 200 years elapsed before coal could be used effectively in the iron production process. The combination of the difficulty of using coal ...
