Sodium Hydrosulfide Method rau Cov Hlau Zoo Tshaj Plaws los ntawm Acid Dej

Tom qab

Hauv ob xyoos dhau los, nrog rau kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis thiab kev tsim kho kev lag luam, kev thov rau cov khoom siv ntxhia tau nce zuj zus ib hnub. Qhov muaj cov mined yooj yim thiab xaiv ib qho nplua nuj ores yog qhov tsawg zuj zus. Cov mining ntawm complex ores nrog nplua embedded particle qhov ntau thiab tsawg thiab qib qis yog nce, thiab muaj kev xav tau ntau ntxiv rau cov khoom ntau thiab zoo. Txhawm rau ua kom tau raws li qhov xav tau ntawm ntau yam kev lag luam ntawm lub teb chaws kev lag luam rau cov khoom siv ntxhia, nws yog qhov yuav tsum tau ua sai sai los tsim cov txheej txheem tshiab ntawm cov ntxhia uas ua tau zoo, muaj txiaj ntsig zoo, thiab muaj txiaj ntsig zoo rau kev tswj hwm ib puag ncig.

Cov txheej txheem ntawm kev rov qab cov hlau muaj txiaj ntsig los ntawm cov dej acidic siv Sodium hydrosulfide muaj tus nqi rov qab siab thiab cov txiaj ntsig kev lag luam tseem ceeb. Cov txheej txheem suav nrog cov kauj ruam hauv qab no:

01.High-Level Dej Cia Tank

Cov dej acidic tsim thaum lub sij hawm mining txheej txheem ua ntej ntws los ntawm cov qib siab dej cia tank mus rau hauv thawj cov hlau tshem tawm cov tshuaj tiv thaiv tank, qhov twg txiv qaub ntxiv. Lub trivalent hlau ions nyob rau hauv cov dej acidic precipitate nrog calcium sulfate, thiab feem ntau ntawm trivalent hlau ions raug tshem tawm los ntawm cov dej acidic.

02.Thawj Iron Removal Reaction Tank

Cov tshuaj tiv thaiv kua ntws los ntawm cov hlau tshem tawm cov tshuaj tiv thaiv tank rau hauv thawj lub tank degassing, qhov twg ntxiv flocculant.

03.Second Iron Removal Reaction Tank

Cov dej nyoos, uas tau muab sib xyaw nrog cov txiv qaub slurry thiab flocculant, ntws mus rau hauv cov hlau tshem tawm cov thickening tank, qhov twg hlau hydroxide thiab calcium sulfate precipitate nyob rau hauv qab ntawm lub thickening tank.

04.Thawj Degassing Tank

Cov dej acidic uas muaj cov hlau ions tseem ceeb, los ntawm qhov ntau ntawm cov hlau ions tau raug tshem tawm, ntws los ntawm lub ntiajteb txawj nqus mus rau hauv cov hlau sulfide reactor.

05.Metal Sulfide Reactor

Nyob rau hauv cov hlau sulfide reactor, cov dej acidic yog tov nrog hlau sulfide precipitate thiab sodium hydrosulfide, tsim cov hlau sulfide hais.

06.Second Degassing Tank

Cov kua sib xyaw uas muaj hlau sulfide concentrates ntws los ntawm lub ntiajteb txawj nqus mus rau hauv lub degassing tank thib ob txuas nrog cov hlau sulfide reactor, qhov twg flocculant ntxiv los txhawb cov agglomeration ntawm hlau sulfide hais rau hauv cov khoom loj.

07.Metal Sulfide Thickening Tank

Cov concentrated hlau sulfide precipitate nyob rau hauv qab ntawm cov hlau sulfide thickening tank. Ib tug scraper tshem tawm cov av nyob rau hauv nruab nrab ntawm lub hauv qab ntawm lub thickening tank. Lub twj tso kua mis reflux tsis tu ncua rov ua dua ib feem ntawm cov dej nag los ntawm hauv qab ntawm lub tank thickening rov qab mus rau cov hlau tshem tawm cov tshuaj tiv thaiv tank, thaum cov dej nag uas tseem tshuav raug xa mus rau cov khib nyiab pob zeb los ntawm lub twj tso kua mis conveying.

08.Metal Sulfide Thickening Tank

Lub twj tso kua mis tsis tu ncua rov ua dua ib feem ntawm cov dej nag los ntawm hauv qab ntawm cov hlau sulfide thickening tank rov qab mus rau cov hlau sulfide reactor. Lwm feem ntawm lub hauv qab precipitate yog xa mus rau lub phaj-thiab-thav duab lim xovxwm kom concentrated rau hauv hlau sulfide concentrate.

Qhov zoo ntawm txoj hauv kev kom rov qab tau cov hlau muaj txiaj ntsig los ntawm cov dej acidic siv sodium hydrosulfide yog raws li hauv qab no:

Ncaj nraim rov qab tau cov hlau muaj txiaj ntsig los ntawm cov dej khib nyiab uas tsim los ntawm cov mines raug nqi txog ib nrab ntawm cov txheej txheem kev ua ntxhia. Qib ntawm cov khoom muaj txiaj ntsig zoo ntawm cov hlau sulfides yog ze li ob npaug ntawm cov txheej txheem kev ua cov ntxhia, nrog rau kev rov zoo siab thiab cov txiaj ntsig tseem ceeb ntawm kev lag luam. Cov dej khib nyiab tom qab rov qab muaj tsawg dua cov hlau hnyav ions, ua rau cov nqi kho cov dej khib nyiab qis dua thiab cov txiaj ntsig zoo ib puag ncig
