Blast Furnace Process - an overview ScienceDirect Topics

2010-01-01  Nowadays, iron is primarily produced through the blast furnace process. However, this production route is characterized by several serious disadvantages, such as the dependence on high-quality coke and iron oxide feedstock, environmental constraints, and the requirement of auxiliary plants (Xu Da-qiang, 2010).

HOW A BLAST FURNACE WORKS - Foundry Gate

The Process . Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches. This ore is either Hematite (Fe 2O 3) or Magnetite (Fe 3O 4) and the iron content ranges from 50% to 70%. This iron rich ore can be charged directly into a blast furnace without any

2018-06-21  A further lowering of the iron ores in the blast furnace leads to the temperature zone of 400 °C to 800 °C. In this region, the so-called indirect reduction of iron ores to iron by carbon monoxide takes place. The carbon monoxide gas (C O) is oxidized to carbon dioxide (C O 2) by absorbing the oxygen contained in the iron oxide (O).

Ironsand - Wikipedia

Ironsand is found worldwide. Although the iron mineral composition of the ironsand is mostly magnetite, the sand is usually mixed with other types of sand that washes downriver or ashore from mountainous or underwater deposits. The exact composition of the sand mixture may vary drastically even in the same geographic region. In some areas the sand may contain mostly quartz, while in others the sand may be made primarily from volcanic rock such as basalt, depending o

The Ironmaking Process New Zealand Steel

The New Zealand Steel plant at Glenbrook is unusual in that the huge blast furnaces that dominate the processes at most steel works around the world are not present. This has eventuated because of the nature of the ore mined locally and used in the process. Early pioneering experiments failed to successfully smelt iron from New Zealand's west coast ironsand deposits because the magnetite ore ...
