Hauv cov chaw ua cov khoom siv hauv av, theem sib tsoo yog qhov tseem ceeb uas siv nyiaj ntau thiab siv zog ntau. Theem sib tsoo tswj kev hloov pauv ntawm cov noob hauv tag nrho cov txheej txheem ua cov khoom siv hauv av, uas muaj feem cuam tshuam loj rau qhov nrawm rov qab thiab qhov nrawm tsim khoom. Yog li ntawd, nws yog ib qho teeb meem uas yuav tsum txo cov nqi thiab txhim kho qhov nrawm tsim khoom raws li tus qauv sib tsoo zoo.
Muaj ob hom kev sib tsoo, kev sib tsoo qhib thiab kev sib tsoo kaw. Ob txoj kev sib tsoo no muaj dab tsi tshwj xeeb? Txoj kev sib tsoo twg thiaj li siv tau zoo thiab ua kom cov khoom tsim tau zoo dua? Hauv cov kab lus tom ntej, peb yuav teb cov lus nug no.
Cov yam ntxwv ntawm ob txoj kev sib tsoo
Kev sib tsoo qhib-circuit yog tias, thaum lub sijhawm sib tsoo, cov khoom siv raug pub rau hauv lub tshuab zeb thiab tso tawm tom qab kev sib tsoo, ncaj qha mus rau hauv lub tshuab zeb tom ntej lossis cov txheej txheem tom ntej.
Qhov zoo ntawm kev sib tsoo qhib-circuit yog kev ua haujlwm yooj yim thiab tus nqi qis dua. Thaum qhov tsis zoo yog qhov tsim khoom tsawg dua thiab siv hluav taws xob ntau.
Kev sib tsoo kaw yog tias, thaum lub sijhawm sib tsoo, cov khoom siv raug pub rau hauv lub tshuab zeb rau kev faib tawm tom qab kev sib tsoo, thiab cov hlau tsis tsim nyog raug xa rov qab mus rau lub tshuab zeb rau kev sib tsoo dua, thiab cov hlau tsim nyog raug xa mus rau theem tom ntej.
Qhov zoo tshaj plaws ntawm kev sib tsoo kaw yog qhov nrawm ntawm kev sib tsoo zoo, thiab qhov zoo ntawm kev tsim khoom siab dua. Nyob rau tib lub sijhawm, kev sib tsoo kaw muaj qhov nrawm ntawm kev tsim khoom ntau dua. Txawm li cas los xij, qhov tsis zoo yog tias cov txheej txheem tsim khoom ntawm kev sib tsoo kaw yog qhov nyuaj dua, thiab raug nqi ntau dua li kev sib tsoo qhib.
Cov ntaub ntawv tsis ua raws li txoj cai raug sib tsoo ntau zaus hauv theem sib tsoo kaw kom txog thaum muaj qhov loj me me. Thaum sib tsoo, ntau cov zaub mov tuaj yeem thauj mus rau hauv cov khoom siv sib tsoo, yog li lub zog ntawm lub pob zeb tuaj yeem siv ntau li ntau tau, txhim kho kev siv cov khoom siv sib tsoo, yog li kev ua haujlwm ntawm cov khoom siv sib tsoo tau zoo dua.
Cov khoom siv ntawm ob txoj kev sib tsoo
Thaum xaiv cov khoom siv sib tsoo, lub pob zeb tsis muaj peev xwm tswj tau qhov loj ntawm cov khoom me me. Muaj cov noob zoo tsim nyog thiab cov noob ntxhib tsis tsim nyog hauv cov dej ntws ore, uas tsis haum rau kev sib tsoo qhib sib tsoo cov khoom siv. Rob zeb yog qhov sib txawv, qhov muaj cov pas hlau ntawm cov thaiv tuab yuav raug tawg ua ntej, kev txav mus rau saum toj ntawm cov pas hlau zoo li ntau lub grille, cov khoom zoo tuaj yeem hla dhau qhov sib txawv ntawm cov pas hlau. Yog li ntawd, lub pob zeb pas muaj peev xwm tswj tau qhov loj ntawm cov khoom me me thiab tuaj yeem siv ua cov khoom siv sib tsoo qhib.
Txawm hais tias lub tshuab zeb pob tsis muaj peev xwm tswj tau qhov loj ntawm cov khoom me me, nws tuaj yeem tswj tau qhov loj ntawm cov khoom me me nrog kev pab los ntawm cov khoom siv faib tawm. Lub tshuab zeb yuav tso cov hlau tawm rau hauv cov khoom siv faib tawm. Cov khoom zoo tsim nyog nkag mus rau theem tom ntej los ntawm lub voj voog sib tsoo-kev faib tawm. Yog li ntawd, kev sib tsoo kaw-circuit cov khoom ntxhib tsis tsim nyog tuaj yeem hla dhau lub tshuab zeb ntau zaus, yuav tsum tau sib tsoo kom txog thaum qhov loj ntawm cov khoom me me tsim nyog tuaj yeem tso tawm los ntawm cov khoom siv faib tawm. Yuav luag tsis muaj kev txwv rau cov khoom siv sib tsoo uas tuaj yeem xaiv tau hauv theem sib tsoo kaw.
Kev siv ob txoj kev los ntxuav cov plaub hau
Raws li ntau hom minerals, yam ntxwv, thiab cov kev cai sib txawv ntawm kev ua haujlwm, qhov yuav tsum tau ua kom zoo sib txawv. Lub xeev ntawm cov ntaub ntawv nrog cov khoom sib txawv mus txog qib kev sib cais tsim nyog kuj tsis zoo ib yam.
Hauv kev sib tsoo kaw-circuit, cov khoom siv rov qab mus rau cov khoom siv sib tsoo yuav luag tsim nyog. Tsuas yog me ntsis rov sib tsoo tuaj yeem dhau los ua cov khoom tsim nyog, thiab kev nce ntawm cov khoom siv hauv lub zeb, cov khoom siv los ntawm lub zeb sai dua, lub sijhawm sib tsoo luv dua. Yog li ntawd, kev sib tsoo kaw-circuit muaj cov yam ntxwv ntawm kev tsim khoom siab, qib sib tsoo me me, qhov loj me me thiab sib npaug. Feem ntau hais lus, lub tshuab flotation thiab lub tshuab sib cais sib nqus feem ntau siv cov txheej txheem sib tsoo kaw-circuit.
Qhov kev sib tsoo qhib-circuit yog qhov tsim nyog rau thawj qhov kev sib tsoo. Cov khoom siv tawm ntawm ib ntu ntawm lub tshuab sib tsoo pas nrig nkag mus rau lwm cov khoom siv sib tsoo thiab tom qab ntawd raug sib tsoo (zoo). Ua li no, thawj ntu ntawm lub tshuab sib tsoo pas nrig muaj qhov sib tsoo me dua thiab muaj peev xwm tsim khoom ntau dua, thiab cov txheej txheem yooj yim heev.
Hauv kev xaus lus, nws tuaj yeem pom tias kev xaiv hom kev sib tsoo yog qhov nyuaj heev, uas yuav tsum tau xav txog ntau yam xws li cov khoom siv, cov nqi peev, thiab cov txheej txheem thev naus laus zis. Nws raug pom zoo tias cov tswv lub qhov av yuav tsum sab laj nrog cov chaw tsim khoom siv ua khoom siv nrog cov qauv tsim lub qhov av kom tsis txhob muaj kev poob nyiaj txiag.
