ABSTRACT:
A closed-cover hot cyclone reactor is used to melt and partially reduce particulate iron or ferro-alloy ores fed to it in a stream. Tangential streams of fuel gas or, preferably, producer gas supplied by an associated bath smelter, interact with the spiralling particles as they pass through the reactor. The molten metal travels downwardly along the reactor walls and can be discharged by gravity onto the receiving bath. The system eliminates the need for pelletizing ore and coking coal in smelting of iron products.
