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

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 txheej txheem, cov neeg sawv cev, cov neeg sawv cev hauv nruab nrab, cov neeg sawv cev hauv nruab nrab uas tuaj yeem tiv thaiv lossis txo cov adsorption lossis kev ua tiav ntawm cov Tus sau rau saum npoo ntawm tsis-flotation minerals, thiab tsim hydrophilic 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, txiv qaub cyanide, sodium sulfide, thiab lwm yam. Thaum zinc sulfate yog siv hauv kev sib xyaw nrog lwm tus neeg sawv ntxov, nws yog qhov zoo zinc fix inhibitor. Dab tsi yog qhov inhibition txoj cai ntawm zinc sulfate? Feem ntau, cov nyhuv inisitia tau tsuas ua haujlwm hauv alkaline slurry. Qhov siab dua qhov pH, qhov pom tau cov nyhuv ntau. Hauv dej, cov tshuaj tiv thaiv ntawm zinc sulfate yog raws li hauv qab no: ZNSO4 = ZN (2-) = ZN (+) [ZN (Oh) 2 yog Ib qho kev sib xyaw ua ke amphoteric, yaj hauv acid, tsim ntsev] Zn (Oh) 2 + h2so4 = zso4 + 2h2o. Hauv nruab nrab alkaline, hzno2 (-) thiab zno2 (2-) yog tsim tawm. Lawv adsorbed rau ntawm cov zaub mov thiab txhim kho lub hydrophilicity ntawm cov ntxhia npoo. ZN (Huag) 2 + NAAHH = NAHZNO2 + H2ozn (Oh2 + 2H2O hauv kev ua ke, socium, socium carbonate, socium carbonate, thiab lwm yam Cov. Feem ntau siv cov sib piv yog: cyanide: zinc sulfate = 1: 2 ~ 5 ~ 5. Kev sib xyaw ua ke ntawm cov sulfuric acid thiab cyanide tuaj yeem txhim kho 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 qis thaum lawv txwv tsis pub siv cov zaub mov ua haujlwm: Sphalerite> Chalcoprite> 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.
