The two largest exporters are Brazil and Australia, with about 33% of total world exports each.

Developments in iron ore comminution and classification ...

As mentioned earlier, pebble mills are widely used in the North American taconite iron ore operations. Since the weight of pebbles per unit volume is 35–55% of that of steel balls, and as the power input is directly proportional to the volume weight of the grinding medium, the power input and capacity of pebble mills are correspondingly lower.

Principles of Extractive Metallurgy

• Carbothermic reduction of iron ore (Hametite) in blast furnace is a well known process. Overall process is written as: • Ironore oxide mineral + gangue + Reducer (C) + flux + hot blast oxygen enriched air = Pig iron (liquid) + Slag (liquid) + waste gas (CO,CO2,N2) • Iron ore contains Fe2O3, along with gangue materials such as SiO2, Al2O3.
