| titleOfInvention | Process for extracting metal zinc from high chlorine zinc-containing soot |
| abstract | The invention discloses a process for extracting metallic zinc from high chlorine zinc-containing soot, which comprises the steps of zinc soot alkali washing dechlorination, leaching, goethite-like ore method purification and impurity removal, copper salt deep dechlorination, three-stage purification, electrodeposition and casting; the process adopts a wet alkali washing dechlorination process, realizes zero discharge of wastewater, and has the advantages of simplicity and high chlorine removal rate compared with the traditional fire dechlorination process; the recovery rate of zinc is effectively improved by the specific leaching process; the method adopts a goethite-like method to purify and remove impurities, effectively improves the impurity removal rate and the removal rate by adding modified magnesium diboride and combining three-stage antimony salt continuous purification treatment, and has high zinc recovery efficiency and high grade. |
