The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot combustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron.
Iron produced in the blast furnace contains a high proportion of carbon, typically 4%, and lacks any of the additives needed to give the steel its various special properties. The early ironmaking process. The raw materials for ironmaking, iron ore, limestone and coke, were usually found close to the foundry.
Iron ore pellets are spheres of typically 6–16 mm (– in) to be used as raw material for blast typically contain 64%72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.. The process of pelletizing combines mixing of ...
A blast furnace converts iron ore into hot metal, or pig iron, which will be tapped and transported to another part of the plant for conversion into steel. A tap hole drill removes the plug in the tap hole so the molten iron can be tapped and directed by troughs towards the torpedo car.

is providing BHP 18 autonomous upgrade packages to convert their fleet of Pit Viper 271 rotary blasthole rigs throughout their WA iron ore operations. The contract includes repair work and audits associated with installation, as well as the provision of training, on site service, and support.
A blast furnace is a special type of are used to make iron from furnaces are very large. They can be up to 60 metres (200 ft) tall and 15 metres (49 ft) in blast furnace is the biggest chemical reactor.
The sintering process converts finesized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast .
Ore Mountain, a mile west of the furnace, was the source of the iron ore that was refined to pig iron. Mining was relatively easy because a ... workers broke a clay plug in the tap hole. The ... From the first firing of the blast furnace in 1844, Katahdin Iron Works had to cope with its remote location and problems in smelting the local iron

Kolomela set new record with big blast. Staking started on 12 June 2014 and took just over seven hours to complete, followed by the drilling of 2,542 holes to an average depth of m. The charging of the holes started on 20 June 2014.
This illustration shows the principles common to all coldblast furnaces. Men and boys on the charging bridge tap raw materials from baskets and barrows into the blast furnace. The furnace works continuously, with iron ore and charcoal gradually descending through the stack.

Lump ore can be loaded directly into blast furnaces, is easier to handle during transportation and can be shipped during wet seasons (liquefaction can be an issue with the shipment of iron ore fines during wet weather). For steelmakers it cuts pollution and lowers cost and lump now constitutes between 15%–20% of blast furnace feedstock.
Iron ore is a mineral block found underground. It is the most common mineral that can be used to make tools and armor. It is the most common mineral that can be used to make tools and armor. Contents
