| titleOfInvention | A kind of method to dechlorinate in zinc electrolyte |
| abstract | The invention discloses a kind of method to dechlorinate in zinc electrolyte, specific steps are as follows: low-grade zinc oxide is carried out neutral leaching, then liquid injection after the leaching containing chlorine is dechlorinated in filling, stirring, antichlor, that is, cuprous oxide is added in whipping process, adds industrial sulphuric acid, obtains dechlorination slag and the liquid that dechlorinates；Then sampling analysis copper content is stirred according to copper content plus iron powder when adding iron powder, stirs 30-40min, then analyze copper content, carries out filters pressing when content of copper ion is less than 0.1g/L to get copper ashes is removed；By dechlorination slag and except reaction tank is added in copper ashes, regenerated liquid is then added, adds piece alkali, adjusts Ph, reaction 3-4h is to get regeneration slag and sodium chloride solution；High chlorine water will be added in obtained sodium chloride solution, be first concentrated by evaporation, make high chlorine water close to the crystalline temperature of sodium chloride, then crystallisation by cooling, obtains sodium chloride powder and mother liquor through seperator, regeneration slag can also be recycled.The present invention have it is at low cost, high-efficient, do not have waste water, do not have waste residue, exhaust gas is not a little. |
