Combustion mechanism of benzene in iron ore sintering process …
The iron ore sintering process is the main source of VOCs emission in the iron and steel industry, and its VOCs emission accounts for about 69.6% . The organic compounds in the solid fuel and the oil components from the raw materials such as rolling oily sludge are pyrolyzed in the preheating layer (150–900 °C) to produce VOCs [ 9, 10 ].

The Assay Guide to Iron Ore
What is iron ore? Iron ore is a mineral substance that generates metallic iron (Fe) when heated with a reductant. Iron ore generally comprises iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). Hematite is widely considered one of the most important iron ores due to its high-grade concentrate of iron and its …

How to Extract Iron from Hematite: Methods and Plants
It is easy to extract iron from this kind of haematite by using gravity separation and magnetic separation. Medium-grained hematite refers to iron ore with an embedded particle size between 0.02 and 2mm. This type of hematite is also relatively easy to select, mainly using gravity separation, magnetic separation and magnetic roasting.

Ironmaking 101 – From Ore to Iron with Blast Furnaces
Iron is mainly extracted from hematite (Fe 2 O 3) and magnetite ores. Natural or direct shipping iron ores contain between 50-70% iron and can be fed directly into the blast furnace. Fe 3 O 4 decomposes when heated to ferrous oxide (FeO) and ferric oxide (Fe 2 O 3) via Fe 3 O 4 → FeO + Fe 2 O 3. A specialized type of coal, called hard coal ...
