Process for producing basic lead carbonate |
| abstract |
A process for producing basic lead carbonate is provided. The process comprises: (1) immersing neutralization slag to obtain sodium hydroxide solution; (2) leaching lead chloride slag with the aqueous solution containing sodium chloride and hydrochloric acid, adding sodium sulfide and filtering; (3) neutralizing the filtrate with sodium hydroxide solution, filtering and washing the precipitate; and (4) converting the precipitate to basic lead carbonate with ammonium bicarbonate, crystallizing and washing. Said neutralization slag and lead chloride slag are the redundant slag from fire refining bismuth. Said process makes better use of the redundant slag from fire refining bismuth, saves resources and reduces environmental pollution. |
