How iron is made

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 92-94 iron and 3-5 carbon with smaller amounts of other elements.

Numerical modeling of the iron ore sintering process

Iron ore sintering process. material mass and species, and momentum and energy conservations for both gas and solid phases are included. to solve the momentum equation for gas flow, the relationship between pressure and velocity is quantified using the simple algorithm.19 a simplified melting and solidification model is developed and the.

Blast furnace

The process of making iron is simple. iron ore is basically iron oxide. iron is made by removing the oxygen. this leaves crude iron called pig iron. this process of removing oxygen is called smelting. carbon is used in the reduction process, with the ore heated to a high temperature. carbon easily takes the oxygen off the ore in high temperatures.

Mineralogy of iron ores of different alumina levels from ...

72.1. mineralogy of iron ore the mineralogy of iron ore varies from quite simple hematite and quartzite with little of aluminium mineral to hydrated hematite along with complex gangue minerals like hydrated aluminium silicate or kaolinite al 4sio 10oh 8 and trihydratedaluminium oxide or gibbsite aloh 3. the hematite can be partially hydrat.

Process through multiscale process modeling

7the shaft furnace figure 2 is the core of the dr process. iron ore pellets are charged at the top, descend due to gravity, and encounter an upward counter-flow of gas. the reducing gas co and h 2, plus ch 4, co 2, and h 2o, at about 950 c is injected peripherally at mid-height and exits at the top.

Classification of iron ore

5each ore based iron taste different, there are points of lean iron ore and sub-depleted iron ore. as the yuanjiacun iron ore type is more, structure, structure complex and the various mineral disseminated granularity fine, cause great difficulty to the beneficiation process, resulting so far has not been a comprehensive development and utilization.

Blast furnace process

Combustion process. the iron in the processed ores must be dissolved out by chemical processes. this requires an element that binds oxygen more strongly than iron. this is exactly what carbon can do as a reducing agent.the carbon is fed to the blast furnace in the form of coke pyrolyzed coal from the coking plant.at sufficiently high temperatures, the carbon can participate directly in the ...
