World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore but before all that iron ore can be turned into steel it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

Its production process is basically similar melting pig iron into hot metal and then adding some substances in the hot metal such as oxygen and iron ore which makes it react with the carbon in the hot metal so as to reduce the carbon content in the hot metal. Then pour the purified hot metal into the mold and make it into steel after cooling.
Feb 23 2013· It is an agglomerating process of converting iron ore fines into uniformed sized iron ore pellets which can be charged directly into a blast furnace BF or into a vertical furnace or rotary kiln normally used for the production of direct reduced iron DRI. The iron ore pellets are shown in Fig 1.

Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used.

The raw materials mix or "charge" enters the furnace from the top and hot air is blown or blasted from the bottom causing the coke to burn and the oxygen to combine with carbon in the coke to form carbon monoxide. Now this carbon monoxide that is unstable reacts with the ore to form carbon dioxide and iron. The Separation Of Iron
the three main process steps of the process (fig 1) include (i) heating of iron ore to around 700 deg c (ii) contacting the hot iron ore with pressurized h2 and ch4 gas mixture at a temperature of around 600 deg c and an absolute pressure of around kg/sq cm in a fluidizedbed reactor for conversion of iron oxide to iron carbide with strong .
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.
