A blast furnace is a very large oven in which the temperature may reach 1,500°C (2,700°F). In the blast furnace, coke removes oxygen from iron ore: The limestone removes impurities in the iron ore. Iron produced by this method is about 91 to 92 percent pure. The main impurity left is carbon from the coke used in the furnace.

The charge (ore, limestone, etc.) is loaded at the top and the molten iron and slag are discharged at the bottom of the furnace. The molten iron was tapped and left to cool in moulds known as pigs. This pig iron was a brittle cast iron containing a high percentage of carbon (2–4%), which made it unsuitable for malleable or wrought iron.

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.

In 2018, Australia's EDR of iron ore increased by 3% from 2017 to 49 604 Mt (Table 3). Similarly, there was a 4% EDR increase of contained iron to 24 122 Mt (Table 4). EDR attributable to magnetite deposits have decreased by 1%, likely due to re-assessment of projects and inactivity in the magnetite industry.
