Iron ore is converted into various types of iron through several processes. The most common process is the use of a blast furnace to produce pig iron which is about 9294% iron and 35% carbon with smaller amounts of other elements.
Iron Ore Agglomeration Processes and their Historical Development. There are four types of agglomerating processes which have been developed (Fig 1).
Evolution of Blast Furnace Iron Making. The origin of the first smelting of iron is concealed in the unrecorded history of human civilization. The first evidence of iron implements being used in ancient times actually comes from Egypt where an iron tool was found in a joint between two stones in a pyramid.
The Saga of New Zealand Steel An External Advisor. In March 1961, the Battelle Memorial Institute of Columbus, Ohio, was chosen as adviser on process selection, giving the investigating company the services of an expert noncommercial organisation.
Mineral Processing. If the mineralogy of the ore shows that you can separate discrete particles of the mineral you want from the gangue components of the ore, then it is possible to physically concentrate the valuable mineral and reject the rest.

Metallurgical ContentImpurities in Iron OresHematiteIron Ore FormationOrigin of Iron OreBodiesMagnetiteLimoniteSiderite The iron minerals that are at present used as ores are hematite, magnetite, limonite, and siderite; also, occasionally ankerite, goethite, and turgite. Hematite is the most important iron ore.
then reacts with the iron ore to form carbon dioxide and pure iron. Separating the iron from the slag 2 The melted iron sinks to the bottom of the furnace.
Chalcopyrite ores are usually processed by means of hydrometallurgical or pyrometallurgical processes, but due to environmental aspects and the possibility of increased exploitation of mixed and lower grade ores and relatively small isolated deposits, there has been a worldwide upsurge of interest in the hydrometallurgical processes of this ore .

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace fuel (), ores, and flux (limestone) are continuously supplied through the top of .
