Kev kho dej ntawm cov thee slime

Cov dej ntws los ntawm cov thee yog cov dej ntws los ntawm kev lag luam uas tsim los ntawm kev npaj cov thee ntub, uas muaj ntau cov khoom me me ntawm cov thee thiab yog ib qho ntawm cov chaw ua qias tuaj ntawm cov chaw tsuas thee. Cov dej ntws yog ib qho system polydisperse nyuaj. Nws yog tsim los ntawm cov khoom me me ntawm ntau qhov ntau thiab tsawg, cov duab, qhov ceev thiab lithofacies sib xyaw ua ke hauv ntau qhov sib txawv.

qhov chaw:

Cov dej slurry ntawm cov thee hauv qhov av tuaj yeem muab faib ua ob pawg: ib qho yog tsim los ntawm kev ntxuav cov thee nyoos nrog lub hnub nyoog geological luv dua thiab cov tshauv thiab cov ntsiab lus tsis huv siab dua; qhov thib ob yog tsim tawm thaum lub sijhawm ntxuav nrog lub hnub nyoog geological ntev dua thiab cov thee zoo dua ntawm kev tsim cov thee nyoos.

yam ntxwv:

Cov khoom siv minerals ntawm cov thee slime yog qhov nyuaj heev

Qhov loj me me thiab cov tshauv ntawm cov thee slime muaj kev cuam tshuam loj heev rau kev ua haujlwm flocculation thiab sedimentation

Ruaj khov nyob rau hauv qhov xwm txheej, nyuaj rau kov

Nws cuam tshuam txog ntau thaj chaw, xav tau kev nqis peev loj, thiab nyuaj rau tswj hwm

kev puas tsuaj:

Cov khoom khov uas raug tshem tawm hauv cov dej ntxuav thee ua rau lub cev dej qias neeg thiab cuam tshuam rau kev loj hlob ntawm cov tsiaj txhu thiab cov nroj tsuag

Kev Ntxuav Cov Thee Dej Pov Tseg Cov Tshuaj Lom Zem Ib puag ncig

Kev Ua Phem Rau Cov Tshuaj Lom Zem Uas Nyob Hauv Cov Dej Ntxuav Thee

Vim yog qhov nyuaj thiab ntau yam ntawm lub kaw lus dej slime, cov txheej txheem kho thiab cov teebmeem ntawm cov dej slime sib txawv. Cov txheej txheem kho dej slime feem ntau suav nrog txoj kev sedimentation ntuj, txoj kev gravity concentration sedimentation thiab txoj kev coagulation sedimentation.

txoj kev los nag ntuj

Yav dhau los, cov chaw ua cov thee feem ntau tso cov dej slime ncaj qha mus rau hauv lub tank slime sedimentation rau cov dej nag ntuj, thiab cov dej ntshiab tau rov ua dua tshiab. Txoj kev no tsis tas yuav ntxiv cov tshuaj lom neeg, txo cov nqi tsim khoom. Nrog rau kev txhim kho ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho ntawm kev siv tshuab thee mining, cov ntsiab lus ntawm cov thee zoo hauv cov thee nyoos xaiv nce ntxiv, uas coj teeb meem rau kev kho cov dej slime. Nws feem ntau siv sijhawm ntau hnub lossis txawm tias lub hlis rau ntau cov khoom me me kom nyob hauv cov dej slime. Feem ntau hais lus, cov dej slime thee nrog cov khoom loj, qhov concentration qis, thiab qhov nyuaj siab yog yooj yim rau precipitate ntuj, thaum cov ntsiab lus ntawm cov khoom me me thiab cov av nplaum yog loj, thiab cov nag ntuj nyuaj.

qhov concentration ntawm lub ntiajteb txawj nqus

Tam sim no, feem ntau cov chaw ua thee siv txoj kev nqus dej los kho cov dej slime, thiab txoj kev nqus dej feem ntau siv cov txheej txheem thickener. Tag nrho cov dej slime nkag mus rau hauv cov thickener kom concentrate, cov dej ntws dhau los siv ua dej ncig, thiab cov dej ntws hauv qab yog diluted thiab tom qab ntawd flotation, thiab cov tailings flotation tuaj yeem tso tawm sab nraum lub Hoobkas rau kev pov tseg lossis coagulation thiab sedimentation kho. Piv nrog rau cov nag los ntawm ntuj, txoj kev nqus dej muaj peev xwm ua tiav loj thiab ua haujlwm tau zoo. Cov khoom siv feem ntau siv suav nrog cov thickeners, lim xovxwm, thiab lim dej.

txoj kev coagulation sedimentation

Cov ntsiab lus ntawm cov thee metamorphic qis hauv kuv lub teb chaws yog qhov siab heev, thiab feem ntau ntawm cov thee metamorphic qis yog cov thee nyoos av nkos siab. Cov thee slime tshwm sim muaj cov dej ntau thiab cov khoom me me, ua rau nws nyuaj rau daws. Coagulation feem ntau siv rau hauv cov nroj tsuag npaj thee los kho cov dej slime, uas yog, los ntawm kev ntxiv cov tshuaj los daws thiab cais cov khoom seem hauv cov dej slime hauv daim ntawv ntawm cov khoom loj dua lossis cov flocs xoob, uas yog ib qho ntawm cov txhais tau tias tseem ceeb ntawm kev ua kom tob ntawm cov dej slime. . Kev kho coagulation nrog cov inorganic coagulants hu ua coagulation, thiab kev kho coagulation nrog cov polymer compounds hu ua flocculation. Kev siv ua ke ntawm coagulant thiab flocculant tuaj yeem txhim kho cov nyhuv ntawm kev kho dej slime thee. Cov neeg sawv cev siv feem ntau suav nrog cov inorganic flocculants, polymer flocculants, thiab microbial flocculants.
