Example text

The iron having higher specific gravity, settles down at the bottom of the melt and thereby forming a layer of the molten iron metal. The molten oxide layers in the anionic form, called slag, floats on the surface of the molten melt. This process continues till all the molten iron oxide melts reduced to metallic iron. After the reaction is over, the entire melt is cooled in the crucible of the reactor and the metal and slag layers are separated manually. The details of the reaction mechanism are adumbrated below at Figure 6.
