iron ore extraction process of crude

Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route). The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

Iron oreis produced in around 30 countries – in 2017, the largest producers were Australia, Brazil and China. Around 98% ofiron oreis used in steel-making. During theiron-makingprocess, a blast furnace is fed with theiron ore, coke and small quantities of fluxes (minerals, such as limestone, which are used to collect impurities).

The extraction of iron from its ore is thethirdand the penultimate process inmetallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in …

Ironprocessing -Ironprocessing - Ores:Ironores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributediron-bearing minerals are oxides, andironores consist mainly of hematite (Fe2O3), which is ...

Extraction of CrudeMetals from ConcentratedOre. The concentratedoreis usually converted to oxide before reduction, as oxides are easier to reduce. Thus, isolationof crudemetal from concentratedoreinvolves two major steps: Conversion to oxide. Reduction of the oxides to metal. Conversion to oxide

Theiron-orefines that enter the BF need to go through a pelletizing and sinteringprocess. In other cases, such as the smelting reduction (SR) processes that use the fluidized bed technologies theiron-orefines can directly be charged into the reductionprocessmaking it highly advantageous.

This page looks at the use of the Blast Furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel. Extracting iron from iron ore using a Blast Furnace The common ores of iron are bothiron oxides, and these can be reduced to iron by heating them with carbon in the form of coke.
