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.

摘要： A zinc production method including a chlorination step 101 at which crude zinc chloride vapor 3 and an oxygen gas 2 are obtained by bringing electric furnace dust 1 containing zinc oxide or secondary dust 1 generated at the time of reducing the electric furnace dust in a reduction furnace into contact with a mixed gas containing a chlorine gas 8 and an oxygen-containing gas 10, converting a zinc oxide component in the electric furnace dust 1 or the secondary dust 1 into zinc chloride, and vaporizing the zinc chloride. The zinc production method further includes purification steps 102, 104, and 105 at which a zinc chloride component contained in the crude zinc chloride vapor 3 is separated from components 5 and 7 other than zinc chloride contained in the crude zinc chloride vapor 3 to obtain a purified zinc chloride melt 6, and an electrolysis step 103 at which the purified zinc chloride melt 6 is electrolyzed to obtain a zinc melt 9 and the chlorine gas 8.

摘要： The present invention belongs to hydrometallurgical technology, which relates to the technology of lead production using the wholly hydrometallurgical technology to lead sulfate(PbSO4) residue accompanied the process of zinc smelting through hydrometallurgy or lead mud of lead storage battery. The present technology use CaCl 2 + NaCl as leaching solvent, leach the high leaching slag containing lead sulfate of hydrometallurgical zinc smelting, lead slag of the zinc oxide containing lead after lead leaching or the lead mud of the lead acid storage battery after being disassembled, use zinc to displace lead in the leached solution, recycle lead in the displaced solution, the recycled lead is returned back to the process of displacing of lead, the solution containing CaCl2 + NaCl after zinc recycling is recycled to the process of leaching of chlorine salt of lead sulfate. The present invention has the advantages of low energy consumption, low cost and easy popularization and application, and eliminate utterly the fume pollution of lead fume, lead dust and SO2 etc.
