How hydrogen can help to decarbonise iron making

Once the iron ore is crushed, it goes into the blast furnace (either as lump ore or as agglomerates like sinters and pellets) where a reducing agent, usually a carbon-based material such as coal or coke (a special kind of coal) or natural gas, is burned to produce both heat and carbon monoxide. The carbon monoxide reacts with iron oxides …

Iron Production

Iron ore is usually a mixture of iron and vast quantities of impurities such as sand and clay referred to as gangue. The iron found in iron ores are found in the form of iron oxides. As a result of these impurities, iron must be first separated from the gangue and then converted to …

Kumba Iron Ore Limited production and sales report for …

On the market front, steel production cuts in China have weighed on iron ore prices in recent months. However, increased sales to markets outside of China have supported an average year to date realised price of US$181 per wet metric tonne (wmt) for the third quarter, 17.5% above the benchmark price. ... Year to date, Kumba achieved an average ...

Adapting to Raw Materials Challenges: Part 1

From research and testing in plants by iron ore companies, it has been established that the optimum composition of a DR-grade oxide pellet depends on specific plant conditions. ... Lump ore also can change the chemistry and impact the final product. When moving to lump ore, attention should be paid to the chemical properties. Some lump has been ...

Estimating the lump to fines composition split in iron …

composition, not only in iron, but also in phosphorus, silica and alumina. The customer blast furnaces are tuned to receive ore of the agreed target composition. Issues relating to quality control in iron ore production are discussed in [1,2]. When ore is crushed and split into lump and fines components, there are

HYL Process for Direct Reduction of Iron Ore – IspatGuru

Energiron direct reduction process (HYL process) uses a shaft reduction furnace to produce DRI. It is designed to convert iron pellet/lump ore into metallic iron by the use of reducing gases in a solid-gas moving bed shaft furnace. O2 is removed from the iron ore by chemical reactions based on H2 and CO, for the production of highly …
