The HIsmelt Iron

The process works like this - iron ore fines coal and fluxes are injected directly into the melt in the SRV On contact the coal breaks up and the carbon reacts with the oxides in the iron-bearing feeds and forms carbon monoxide The rapid heating of the coal cracks the coal volatiles releasing hydrogen The rapid expulsion of the carbon monoxide hydrogen and nitrogen carrier gas from the

DRI production

DRI production Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state i e without melting as in the blast furnace The reducing agents are carbon monoxide and hydrogen coming from reformed natural gas syngas or coal Iron ore is used mostly in pellet and/or lumpy form The chemical reactions involved in the direct reduction of

Iron processing

Iron processing use of a smelting process to turn the ore into a form from which products can be fashioned Included in this article also is a discussion of the mining of iron and of its preparation for smelting Iron (Fe) is a relatively dense metal with a silvery white appearance and distinctive magnetic properties It constitutes 5 percent by weight of the Earth's crust and it is the


The result is a revolutionary technology which reduces the size of a typical pelletizing plant by half the Primetals Technologies Circular Pelletizing Technology – the world's most compact plant for pelletizing by far thanks to a low building profile short process air ducts and completely standardized equipment - is a milestone in the cost-minimized iron production with in-house made

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 Pig iron has only limited uses and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing the carbon

Blast Furnace operation HOW A BLAST FURNACE WORKS

Iron oxides can come to the blast furnace plant in the form of raw ore pellets or sinter The raw ore is removed from the earth and sized into pieces that range from 0 5 to 1 5 inches This ore is either Hematite (Fe 2 O 3) or Magnetite (Fe 3 O 4) and the iron content ranges from 50% to 70% This iron rich ore can be charged directly into a blast furnace without any further processing Iron

Emerging Technologies for Iron and Steelmaking

Simultaneous independent development of the direct iron ore smelting (DIOS) process in Japan 28-30 and the AISI direct steelmaking process in North America 31 23 produced two similar routes to hot metal production Both processes utilize a smelting reactor where the primary reactions occur in a deep slag bath as opposed to in the metal phase as in HIsmelt Pre-reduced iron ore coal and

Steps in the Modern Steelmaking Process

The Modern Steel Production Process Methods for manufacturing steel have evolved significantly since industrial production began in the late 19th century Modern methods however are still based on the same premise as the original Bessemer Process which uses oxygen to lower the carbon content in iron Today steel production makes use of recycled materials as well as traditional raw

091102 Iron ore

2 1 Description of the production process In the iron ore sector iron ores and concentrates (excluding roasted iron pyrites) are produced A distinction can be made between non-agglomerated iron ores and concentrates (sinter fines) and agglomerated iron ores and concentrates The main products within agglomerated iron ores are iron ore pellets which are used as raw material for primary iron
