| titleOfInvention | A kind of recovery method of leaching acid lead mud |
| abstract | The invention discloses a recovery method of acid-leaching lead mud, belongs to the technical field of lead-acid batteries, and solves the problems of high desulfurization cost and untreated by-products of acid-leaching lead mud in the prior art. In the recovery method of the present invention, the mother liquor ammonium chloride is used as the desulfurizing agent to carry out the desulfurization reaction of the lead mud to be treated, the ammonium sulfate solution obtained from the desulfurization is subjected to a regeneration reaction with calcium hydroxide, and the ammonia water obtained from the regeneration is reacted with the lead paste obtained from the desulfurization to obtain oxidation Lead paste and regenerated ammonium chloride, lead oxide paste is used in the battery paste mixing process, and regenerated ammonium chloride is used as mother liquor ammonium chloride, so as to complete the recovery of acid-sprayed lead sludge. The recovery method of the invention can be used for the recovery of acid-sprayed lead mud. |
