Lub inhibition lub hauv paus thiab daim ntawv thov ntawm zinc sulfate inhibitors

Txhawm rau txhim kho kev xaiv cov txheej txheem (txhim kho cov txiaj ntsig thiab cov neeg sawv cev ua npuas dej uas muaj txiaj ntsig zoo ntawm cov roj hmab, cov tswj hwm feem ntau siv hauv cov txheej txheem frotation. Cov kev kho hauv cov txheej txheem frotation suav nrog ntau cov tshuaj lom neeg. Raws li lawv lub luag haujlwm hauv cov txheej txheem frolotation, lawv tuaj yeem faib ua cov neeg tsis muaj yeeb yaj kiab, cov neeg sawv cev hauv nruab nrab, cov neeg sawv cev nruab nrab, discidants, thiab lwm yam.

Thaum lub sijhawm flotation flotation, inhibitors yog cov neeg sawv cev uas tuaj yeem tiv thaiv lossis txo cov zaub mov tsis yog-fydrophilic zaj duab xis nyob rau saum npoo ntawm cov merals.

Zinc Sulfate yog ib qho tseem ceeb inhibitors hauv cov txheej txheem frolotation.

Lub inhibition txoj ntsiab cai ntawm zinc sulfate inhibitor
Hauv kev ua lag luam pob qij txha, zinc sulfate, kua qaub cyanide, sodium sulfide, thiab lwm yam zoo zinc sib xyaw ua ke thaum siv ua ke nrog lwm cov neeg sawv daws.

Dab tsi yog qhov inhibition txoj cai ntawm zinc sulfate?

Feem ntau, lub qhov cuam tshuam tsis ua haujlwm tsuas yog ua haujlwm hauv alkaline pulp. Qhov siab dua qhov pH, qhov pom tau cov nyhuv ntau. Hauv dej, zinc sulfate reacts raws li hauv qab no:

ZSO4 = ZN (2 +) + So4 (2-)

ZN (2 +) + 2h2o = ZN (Oh) 2 +) [Zn (Oh (Oh (Oh)

ZN (Huag) 2 + h2o4 = Zso4 + 2h2o

Hauv kev tshaj tawm cov medolaline, Hzno2 (-) thiab Zno2 (2-) yog tsim tawm, uas tau tshaj tawm ntawm cov zaub mov thiab txhim kho lub hydrophilicity ntawm cov ntxhia saum npoo.

ZN (Huag) 2 + NAOH = Nahzno2 + H2O

ZN (OH2 + 2NONOH = NA2ZNO2 + 2H2O

Hauv kev ua tiav ntawm cov ntxhia, zinc sulfate feem ntau tsis siv ib leeg ua cov neeg ua haujlwm, socium carbonate, socium carbonate, socle carbonate, socle carbonate, socle carbonate, socle carbonate yog: zinc sulfate = 1: 2 ~ 5. Cov kev siv ua ke ntawm cov sulfuric acid thiab cyanide tuaj yeem txhim kho cov kev tiv thaiv kev tiv thaiv ntawm sphaalerite.

Daim ntawv thov ntawm zinc sulfate inibitors
Zinc sulfate yog cov kua qaub alkali tsis muaj zog, ntau zaus nrog 7 cov khoom lag luam huv (Znsdly (Znaus), yooj yim soluble hauv dej. Cov ntsiab lus zinc sulfate cov ntsiab lus hauv nws cov tshuaj noo yog 29.4%, thiab cov tshuaj aque yog acidic. Cov. Hauv kev tsim khoom, nws feem ntau siv los ua 5% kev daws teeb meem.

Thaum zinc sulfate yog tov nrog txiv qaub, nws yog ib qho ua tau zoo inhibitor ntawm zinc sulfide cov zaub mov (zinc tov lossis hlau sib xyaw). Qhov siab dua tus nqi ntawm cov slurry, tus muaj zog dua inhibitos cov nyhuv ntawm zinc sulfate ntawm zinc sulfide cov zaub mov.

Nws yog feem ntau ntseeg tias inhibitos nyhuv ntawm zinc sulfate ntawm zinc sulfate cov zaub mov yog vim yog cov adlo2 (2-) tsim tawm hauv cov khoom siv tshuaj pleev ib ntus ua hydrophilic zaj duab xis. Tshwm sim los ntawm.

Zinc Sulfate qee zaum sib xyaw nrog cyanide thiab txiv qaub. Qhov kev txiav txim nqis ntawm lawv cov kev txwv ntawm cov txiv ntoo uas yog: Sphalerite> Pyrite> Marcasite> Chertite Chalcocite kuv. Yog li ntawd, thaum sib cais polymetallic sulfide cov zaub mov, noj ntau npaum li cas ntawm inhibitors yuav tsum raug tswj hwm nruj.
