From the Soil to the Iron Product

During this process the water content of the iron ore is released, and its structure becomes looser, which makes it easier to smelt. Finally, we break up the burnt iron ore into 2-3 cm pieces to make it easier to load the iron ore into the furnace during the smelting process (See Figure 3). Step 3. Building furnaces.

Iron Ore Analysis & Process Optimization Solutions | …

To efficiently process iron ore for high quality steel production, frequent ore grade monitoring, during all steps of downstream processing, is mandatory.
