Abstract：Experiment or industrial practices on disposal of dust generated by iron and steel plant, production of sponge iron and comprehensive utilization of compound mineral were introduced briefly and the development of Rotary Hearth Furnace(RHF) was comprehensively discussed in domestic and overseas. American, Japan, China and Korea had disposed the dust and sludge generated by iron and steel plant. Hazardous elements were removed from the dust and the zinc was recycled for improving the environment. At the same time metallized pellets and hot briquette iron(HBI) were produced by RHF used as raw materials of BF. In addition, DRI produced by RHF was used as raw materials of steelmaking which can be simplified the steelmaking process. Many compound iron ore containing vanadium, titanium, boron, magnesium, rare earth were investigated in lab and industry.
