Abstract: The dust ash from the production phases of iron and steel metallurgical enterprises is rich in valuable elements such as iron, carbon, zinc, potassium and sodium. Directly recycling this dust back into the blast furnace smelting process not only leads to the waste of resources such as zinc, potassium, and sodium. It also affects the furnace condition and reduces its service life due to the cyclic zinc accumulation in the blast furnace. In order to reduce the consumption of production resources, promote the economic benefit of enterprises, and realize the green development of the iron and steel industry, optimizing and implementing the treatment of dust removal ash is an inevitable option. The paper introduced the classification and sources of zinc-containing dust ash, systematically described the processes and mechanisms of various zinc-containing dust ash dezincification technologies, and discussed the progress of zinc dezincification technologies for zinc-containing dust ash. Finally, it presented the prospects and suggestions for developing dust ash dezincification technologies from zinc resource recovery, clean energy utilization, and development of low-carbon processes.
