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 frotation, lawv tuaj yeem faib ua cov neeg sawv cev, cov neeg sawv cev, cov neeg sawv cev hauv nruab nrab, thiab lwm yam tuaj yeem txhim kho lub peev xwm ntawm cov khoom siv ntxhia rau Adsorb cov neeg sau khoom. Kev ua kom lub tshuab ua kom muaj zog yog: (1) sib sau ua kom muaj cov yeeb yaj kiab insoluble ua rau cov ntxhia saum npoo av uas yooj yim los cuam tshuam nrog tus sau; (2) tsim cov ntsiab lus nquag ntawm cov ntxhia uas yooj yim los cuam tshuam nrog tus sau; (3) Tshem tawm cov khoom siv hydrophilic ntawm cov ntxhia. Zaj duab xis txhawm rau txhim kho cov ntab ntawm cov av hauv av: (4) Tshem tawm cov hlau ions hauv slurry uas tabkaum lub flotation ntawm lub hom phiaj ntxhia. Tooj liab sulfate activator yog ib qho tseem ceeb activator.
Cov khoom thiab kev faib tawm ntawm tooj liab sulfate activator
Lub luag haujlwm ntawm cov kua liab activator hauv pob zeb hauv ntxhia ntxig yog feem ntau los txhim kho nws txoj kev ua tau zoo ntawm cov tshuaj lom neeg ntawm cov ntxhia. Ntawm no yog nws ua haujlwm li cas: 1. Tshuaj lom neeg sulfate (cuso₄) ua raws li tus txheej txheem thaum lub flotation txheej txheem ntawm qee yam meralals. Nws tuaj yeem hnov cov tshuaj nrog cov pob zeb hauv av, tshwj xeeb yog cov khoom siv sulfide (xws li cov pyrite, sphalerite, thiab lwm yam) thiab lwm yam sib txuas. Cov tooj liab ions tuaj yeem sib txuas nrog cov sulfides ntawm cov ntxhia thiab hloov cov tshuaj lom neeg ntawm cov ntxhia. 2. Hloov cov khoom saum npoo av: Ntxiv rau ntawm tooj liab sulfate tsim cov tshuaj lom neeg tshiab, ua rau lub pob zeb me me lossis hydrophobicity ntawm cov ntxhia saum npoo kom hloov. Piv txwv li, tooj liab ions tuaj yeem ua kom cov ntxhia cov khoom ntau dua hydrophobic, nce lawv lub peev xwm los ua raws li huab cua bubbles thaum flotation. Qhov no yog vim tias tooj liab sulfate tuaj yeem ua rau cov neeg sulfate tuaj yeem hnov mob ntawm cov zaub mov ntawm cov zaub mov, yog li hloov chaw sib txawv ntawm cov ntxhia. 3. Txhim kho kev xaiv: tooj liab sulfate tuaj yeem txhim kho kev xaiv ntawm cov txheej txheem frotation los ntawm kev ua kom cov flotation ntawm cov zaub mov tshwj xeeb. Rau qee cov minerals, nws tuaj yeem nce lawv cov kev ua haujlwm ntawm kev ua kom zoo thiab rov qab los. Qhov no yog vim los ntawm kev ua kom muaj zog, cov pob zeb hauv av yog qhov yooj yim dua nrog cov neeg ua kom sib xyaw ua ke (xws li kev txhim kho cov frotation efficiency ntawm cov ntxhia. 4. Txhawb nqa cov adsorption ntawm cov neeg sib sau: tooj liab sulfate tuaj yeem txhawb nqa cov ntawv sau ua ke (xws li Xantoration Flotation (tshuaj ntsuab, thiab lwm yam khoom ntawm cov ntxhia. Cov txiaj ntsig nce qib no ua rau lub colle collector los khi rau cov ntxhia saum npoo ntau dua, txhim kho lub peev xwm sib sau thiab xaiv lub sijhawm thaum lub sij hawm flotation. Hauv cov ntsiab lus, tooj liab sulfate ua raws li cov activator hauv cov tshuaj txhuam me, thiab kev txhawb nqa cov khoom siv roj hmab ntawm cov roj av, thiab kev txhawb nqa cov khoom siv roj av, thiab kev txhawb nqa cov pob zeb ua kom zoo thiab xaiv cov zaub mov.
Daim ntawv thov ntawm tooj liab sulfate activator
Tooj liab sulfate yog dav siv nyob rau hauv cov ntxhia flotation. Ib rooj plaub classic yog lub flotation ntawm tooj liab mines. Nyob rau hauv cov txheej txheem kho mob ntawm tooj liab ore, tooj liab sulfate feem ntau siv los ua kom muaj pyrite los txhim kho nws txoj kev ua kom zoo nkauj nrog cov neeg sau (xws li Xanthate). Los ntawm kev nqis tes ua ntawm tooj liab sulfate, lub saum npoo ntawm pyrite tau yooj yim dua rau adsorb cov neeg sau, yog li kev txhim kho kev rov qab tus nqi thiab flotation efficiency ntawm tooj liab ore. Lwm qhov piv txwv yog cov flotation ntawm cov txhuas-zinc ore, qhov twg tooj liab sulfate yog siv los qhib sphalerite thiab txhim kho nws qhov kev ua tau zoo thaum lub sijhawm flotation. Cov ntawv thov no qhia txog qhov tseem ceeb ntawm tooj liab sulfate ua ib tug activator hauv cov ntxhia plab mog.
