مصنع لتجهيز البوكسيت/Gas Based Sponge Iron Plant Using Magnetite Ore
GoodRich offers a new technology from China, which can beneficiate low grades of hematite / limonite / goethite ores (including BHQ BHJ) and also recover the leftover tailings from the conventional beneficiation plants, by converting them into magnetite ores, using the fluidised bed reductionroasting method. Once the iron ore becomes magnetite, it is much easier to beneficiate pelletise it.

The Höganäs process is a direct reduction method for production of sponge iron powder using magnetite ore (Fe3O4) and carbon as raw materials. The reduction process takes place in a gas fired tunnel kiln at around 1200°C for 60 hours producing a sponge iron cake that is crushed, milled and magnetically separated from impurities. The final reduction is made in a continuous furnace under ...

A new route for making steel from iron ore based on the use of hydrogen to reduce iron oxides is presented, detailed and analyzed. The main advantage of this steelmaking route is the dramatic reduction (90% off) in CO2 emissions compared to those of the current standard blastfurnace route. The first process of the route is the production of hydrogen by water electrolysis using CO2lean ...
though the use of fossilbased reducing agents for the iron and steel making cause the highest share of CO 2 emissions.

Iron ore reactor is a moving bed reactor to produce sponge iron product from iron ore. Gas and solid phases are passed in counter current. In general, sponge ore reactor is divided by 3 zones, which are referred to as reduction, isobaric, and cooling zones. The simple scheme of iron ore reactor is shown in Figure 1. In the reduction zone, there are some reactions occurring between reduction ...
