| titleOfInvention | Cupric sulfate centrifuge mother liquor method for crystallising |
| abstract | The invention discloses a kind of Cupric sulfate centrifuge mother liquor method for crystallising, it includes：Stabilizer is added into Cupric sulfate centrifuge mother liquor, crystalline mother solution is obtained with insulation reaction after liquid caustic soda regulation pH value, thickening, centrifugation desalination；Crystalline mother solution is cooled to less than 30 DEG C under agitation, hydrochloric acid, which is added portionwise, finally makes the pH value of mother liquor to 5.3~5.7 and insulation reaction, continue to be cooled to and be incubated 4~10 hours at 0 DEG C, the temperature of mother liquor is set to be maintained at 5~8 DEG C before discharging, separation of solid and liquid after discharging, the liquid alkali isolated adjusts pH value and obtains dimehypo to 6.8~7.2, and the solid isolated obtains Cupric sulfate after drying.Each influence factor of the present invention in Cupric sulfate crystallization process, has formulated a kind of compound crystallization mode, Cupric sulfate flour extraction can be made to reach 45%, Determination of Shachongdan is maintained at more than 95%, and this method has more preferably prospects for commercial application. |
