Gulhan Ozbayoglu, in Comprehensive Energy Systems, 2018. Coal is used in iron and steel industry. Coking coal is an essential input for production of iron and steel. The largest single use of coal in the steel industry is as a fuel for the blast furnace and for the production of metallurgical coke for reduction of iron ore or for injection with the hot blast.
Bituminous coal must meet a set of criteria for use as coking coal, determined by particular coal assay techniques. These include moisture content, ash content, sulphur content, volatile content, tar, and plasticity. Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. Coke from coal is gray, hard, and porous.
Highgrade hematite ore is referred to as direct shipping ore (DSO) because after it is mined, the ores go through a relatively simple crushing and screening process before being exported for use in steelmaking. Australia's hematite DSO from the Hamersley region in Western Australia averages from 56% to 62% iron. Like hematite ores, magnetite ores require initial crushing and screening, but ...
The first iron mining techniques used charcoal which was mixed with iron ... Iron ore, a type of coal called coke (which contains 85% carbon) and lime are added to the top of the blast furnace. Hot air provides the oxygen for the reaction. The temperature of a blast furnace can be up to 1200°C. The reaction takes place inside the furnace and molten iron is removed from the bottom. Lime ...

Crushing At the processing plant, the taconite is crushed into very small pieces by rock crushing machines. The crushers keep crushing the rock until it is the size of a marble. The rock is mixed with water and ground in rotating mills until it is as fine as powder. Separation The iron ore is separated from the taconite using magnetism. The remaining rock is waste material and is .
This process varies depending on the ore source, but typically involves various stages of crushing and grinding to reduce the size of the iron ore. Separation techniques such as magnetic separation or froth flotation are then used to separate the gangue (unwanted) materials from the iron content.

Iron ore fines are created as a result of mining, crushing and processing the larger pieces of ore. Iron ore fines are less desirable (and of lower value) as they need to be sintered before they can be utilised, otherwise it will effectively smother the air flow in the blast furnace. The reason lump is preferred is that when it is fed into a blast furnace for
