摘要： A method and a device for recovering zinc from electric furnace steelmaking dust, which are capable of recovering high-purity metal zinc for relatively short time. A Ca mixing and heating means obtains ZnO and 2CaO·Fe 2 O 3 by mixing electric furnace steelmaking dust with calcium compound and performing heat treatment in a non-reducing atmosphere at not lower than 960°C and not exceeding 1100°C for one to three hours. An iron powder mixing means mixes the ZnO and 2CaO·Fe 2 O 3 with iron powder, and compact the mixture. A reduction and volatilization means obtains a solid metal zinc piece by disposing a green compact in a decompression container 21, decompressing and heating the inside of the decompression container to generate zinc vapor, and cooling and coagulating the zinc vapor. A zinc acquisition means acquires lumpy zinc by immersing the metal zinc piece in a NaCl-KCl based multi-component chloride flux and cooling the flux solution.
