Jun 21, 2016· The word basic is added with it for the chemical nature of the refractories magnesium oxide and calcium oxide. The basic principal of it is to lower carbon content in pig iron in order to make pure steel from it. In this method, iron ore is mixed with coke and heated highly in order to form an ironrich clinker called 'sinter'.
Blast furnace, a vertical shaft furnace that produces liquid metals by the reaction of a flow of air introduced under pressure into the bottom of the furnace with a mixture of metallic ore, coke, and flux fed into the top. Blast furnaces are used to produce pig iron from iron ore for subsequent
International Iron Metallics Association. The IIMA is dedicated to those involved in the orebased metallics value chain raw material supply, production and transformation, trading and distribution, transportation and logistics, technology and equipment.
Apr 25, 2017· China, followed by Australia and Brazil are the three top ranking iron ore producing countries in the world. Iron ore being extracted at the massive Mikhailovsky Mine in Russia.

A Blast furnace is a gigantic, steel stack lined with refractory where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. All the three ingredients are crushed into small round pieces and mixed and put on a hopper which controls the input.
Sep 19, 2017· Sintered iron ore and coke are layered inside a 100 m long furnace, then hot air at 1200 degree Celsius is blown into the blast furnace from the bottom causing the coal to burn and this heat, in turn, burns the iron ore to create molten iron at a temperature of 1500 degree Celsius. This is also called hot metal (pig iron) in the industry.
This statistic displays the iron ore production in Mexico from 2006 to 2016, by gross weight and metal content. In 2016, the metal content of the iron ore produced in Mexico was some million ...
Of this, approximately 570 million tonnes were used by the global steel industry, and the rest were used in foundries or in some very small and outdated iron steel production facilities around the world (which are not counted in official steel production statistics). Iron ore and metallurgical coal are used mainly in the blast furnace process ...
depend on production techniques and on the quality of the basic materials. Iron Ore classification – The basic material for iron and steel production is iron ore or ferrous scrap. Iron ores are classified based on shape and volume. Iron fines have a majority of particles with a diameter of < mm; iron lump ore .
The figure shows a flowchart of the integrated manufacturing process for iron and steel using the blast furnace and basic oxygen furnace (denoted BF and BOF hereinafter, respectively), which is presently the most commonly used method (51% of world steel production).
BACKGROUNd TO KUMBA IRON ORE Kumba Iron Ore Ltd is the fifth largest supplier of seaborne iron ore in the world. Operating through its 74%held subsidiary Sishen Iron Ore Company (SIOC), Kumba has two operational mines at Sishen and Thabazimbi, with a third, Kolomela, scheduled to begin production in .
Coal is cleaned of impurities in a coke furnace, yielding an almost pure form of carbon. A mixture of iron ore and coal is then heated in a blast furnace to produce molten iron, or pig iron, from which steel is made. ArcelorMittal has a diversified fleet of production facilities to make steel, both basic oxygen furnaces and electric arc furnaces.
