6.5 of CO2 emissions derive from iron and steel production IEA 2010 1 Mineral Extraction. Iron ore. Iron doesnt occur naturally. Being highly reactive,bines easily with other minerals to form ores. Those with the highest iron content are found near the surface of the earth and are relatively easy to mine.
The iron and steel industry, including primary and secondary producers,posed ofpanies . A general flow diagram for the production of raw steel from iron ore is presented in Exhibit 2. .. Extraction/Beneficiation Wastes. Chat
Extraction of Iron from its ores Iron dressing Reduction. S + O 2 SO 2. 4 P + 5 O 2 2 P 2 O 5. Roasting is the process of heating iron ore strongly in dry air for drying the ore and expelling humidity It is used to increase the percentage of iron in the ore and for the oxidation of some impurities such as sulphur and phosphorus..
Extraction of Iron from its ores. Extraction of iron or its metallurgy is the process of obtaining this metal in a form where it can be put to practical use, and this process of extraction consists of three stages Ore dressing, Reduction of ores and Iron production. Extraction of Iron from its ores.
Extraction of iron takes place on an industrial scale in blast furnaces. Blast furnaces aremon part of large industrial steelmaking plants, which also include coke ovens, sintering beds, and other areas for ore dressing. Iron is extracted from its ore using carbon in the form of coke.

Liquid phase extraction of iron from iron ore fines using acetyl acetone. Mineral Processing, Cape Town, South Africa, 78 August 2013
The plants for the production of pig iron or steel are called ironworks. An ironworks or iron works is an industrial plant for the production of steel from iron ores! Before the iron ores can be fed to the ironworks, they must first be mined ore extraction and specially processed for the blast furnace process ore processing.
Iron ore of 70 iron content and manganese ores were found. In 1881 the industrial extraction of iron ore began, alongside other developments such as the construction of Kryvyi Rih railway. By 1884 over 100 000 tons of iron ore had been extracted, and the railway though Kryvyi Rih, 477 versts 505,6 km long, from Yasynuvata station via Kryvyi
Iron Iron ore reserves in the country are estimated at 1750 crore tonnes. Major iron ore mining is done in Goa, Madhya Pradesh, Bihar, Karnataka, Orissa and Maharashtra. Aluminium Its chief ore, bauxite is available in India in abundance. The annual production of bauxite is estimated to be more than 2 million tonnes.
Suggested Approach for Various Sectors in an Integrated Steel Industry A single operation of pig iron production requires about 150 tons of water and 3.5 tons of air to produce one ton of iron. Likewise, every tonne of steel produced gives about 20 tonnes of liquid wastes, 5 tonnes of waste gases and 1 ton of solid wastes.
