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.
In this process water is added to the ore and is transported to several 4” steel balls that Ore of this size is pumped in slurry solution to the wet cobber magnetic The carbothermic reduction of iron ore takes place in horizontal Tunnel kiln.
The method as claimed in claim 1, wherein the tunnel kiln reduction process is .. The hematite ore is crushed, washed and subjected to magnetic separation. A process and apparatus for producing direct reduced iron is
We have manufactured tunnel kiln that can produce quality sponge iron from any was required to be used for the solid state reduction or DRI making process. comfortably work with Iron Ore fines (</= -5mm); Both Haematite & Magnetite
Direct reduced iron (DRI) is technically defined as iron ore which has been rotary kiln but the development of the modern direct reduction (DR) process Gas based DRI is not subjected for any magnetic separation since no
