A Direct Reduced Iron (DRI) plant
DR pellets – the raw material – are fed into the reactor. Hydrogen is the reducing gas and is circulated in a closed-loop system and then recycled. Hot-reducing gas flows through the iron ore, from the bottom to the top, according to the counterflow principle. Oxygen content in the iron ore is reduced and "direct reduced iron (DRI)" is ...

Direct-reduced iron
Most of the iron used by humanity goes through the process of direct reduction. The main and most economical method of recovering iron from its ore known is the carbothermal method of direct reduction from the ore by means of carbon-bearing materials: FeХOY+C=Fe+CO2. The oldest and most common method is to smelt iron (pig iron) in …

Sponge Iron or Direct Reduce Iron Plant
Sponge Iron or Direct Reduced Iron is produced by reducing Iron Ore (in the form of lumps/pellets) using non-coking coal in a rotary kiln. The coal acts as the fuel as well as a reducing agent & Oxygen is removed from the Ore to produce Sponge Iron. Since the reduction takes place in the solid phase only it is called Direct Reduction.

3 key steps for forging a path to green steel | BCG
Here are three actions they should consider taking. Accelerate high-grade production. Iron ore mining companies already prioritize the production of better-quality ores, but they need to do more. Ores with more iron content and fewer impurities enable manufacturers to produce higher-value-added green steel efficiently.

Direct Reduction of Iron Ore with Green Hydrogen
declining price of shale gas, there has been an upsurge in the installation of DRI plants in the US [44]. Shaft furnaces, rotary kilns, rotary hearth furnaces and fluidized bed reactors are used for direct reduction of iron ore. Most of the DRI plants use shaft furnace reactors developed by MIDREX [43] and HYL-Energiron [45] technologies.
