Ntxiv rau cov zaub mov, cov khoom siv ntawm cov khoom siv ntxhia kuj suav nrog cov pob zeb pov tseg. Nws yog dab tsi? Vim li cas lawv thiaj tau lub npe zoo li no? Cov lus teb rau cov lus nug no yuav muab luv luv hauv kab lus. Nws tseem yuav piav qhia luv luv txog qhov kev tiv thaiv yog dab tsi thiab piav qhia nws cov txiaj ntsig zoo.

Kev txhais lus

Nyob rau hauv cov tsiaj khoob hauv kev tshawb fawb thiab kev lag luam nkag siab cov tsiaj uas tsis sawv cev rau qhov muaj nqis. Lawv feem ntau nrog cov pob zeb hauv av thiab feem ntau nyuaj rau kev sib cais, xav tau cov txheej txheem tshwj xeeb.

Yog li, pov tseg pob zeb ore, piv txwv li, muaj oxides ntawm txhuas, calcium, magnesium, silicon. Cov zaub mov tsim los ntawm lawv yog hu ua silicates, aluminosilicates.

Raws li "Mining Encyclopedia" piav qhia, cov pob zeb pov tseg tau muab rho tawm ntawm lub plab nrog rau cov zaub mov thiab xa mus rau cov khoom pov tseg - qhov chaw uas cov khoom siv tsis zoo hauv cov ntxhia tau muab tso rau saum npoo. Kev pov tseg feem ntau ua tiav qhov kev hu ua overburden ua haujlwm hauv quarries, uas qhib kev nkag mus tau zoofossils thiab npaj lawv rau excavation. Cov khib nyiab uas paub zoo tsis muaj dab tsi ntau dua li cov pob zeb pov tseg - roob ntawm cov pob zeb pov tseg uas tau muab rho tawm los ntawm cov mines los yog (ze rau cov mining thiab ua cov nroj tsuag) ua cov khoom pov tseg.

Dab tsi yog kev nplua nuj

Kev ua kom muaj txiaj ntsig yog siv rau hauv qhov xwm txheej uas cov pob zeb pov tseg tsis tuaj yeem sib cais tag nrho ntawm cov zaub mov vim li cas. Lub sij hawm no yog hais txog cov txheej txheem ntawm kev ua thawj zaug ntawm cov khoom siv ntxhia. Lub hom phiaj yog cais cov khoom muaj txiaj ntsig los ntawm cov pob zeb pov tseg thiab los ntawm ib leeg. Qhov tseeb, cov hlau ore, piv txwv li, ntxiv rau cov pob zeb peb tab tom xav txog, tej zaum yuav muaj lwm yam minerals tseem ceeb - oxides ntawm nickel, molybdenum, vanadium, chromium, manganese, tungsten.

Kev txhawb nqa suav nrog ntau theem, uas, dhau los, qee qhov haujlwm tau ua. Yog li, cov theem npaj muaj xws li cov txheej txheem ntawm crushing thiab sib tsoo, kev tshuaj ntsuam (sib cais ntawm pob zeb hais raws li qhov loj me) thiab kev faib.

Nyob rau theem tseem ceeb, cov khoom muaj txiaj ntsig tau muab rho tawm los ntawm cov khoom siv raw - ib lossis ntau dua. Ua li no, lawv cia siab rau qhov sib txawv ntawm cov pob zeb pov tseg thiab cov zaub mov thiab tom kawg los ntawm ib leeg hauv hluav taws xob conductivity, wettability, ntom, sib nqus susceptibility, tshuaj lom neeg, solubility, thiab lwm yam. Cov theem kawg yog lub cev qhuav dej thiab ziab ntawm cov khoom tiav.

Txoj kev ua kom muaj txiaj ntsig zoo

Raws li qhov txiaj ntsig ntawm kev nplua nuj, cov pob zeb muaj zog tau txais, npaj rau kev ua tiav, thiab lub npe hu ua dump tailings, suav nrogfeem ntau yog los ntawm cov pob zeb pov tseg. Cov zaub mov muaj txiaj ntsig yog xyaum tsis tuaj yeem nyob hauv lawv los yog tam sim no nyob rau hauv xws li ib qho kev xav uas ntxiv cov khoom siv raw li no tsuas yog siv tsis tau. Tsis tas li ntawd, nyob rau hauv cov txheej txheem ntawm enrichment, cov khoom nruab nrab kuj tuaj yeem tau txais, qhov concentration ntawm cov khoom siv tau zoo nyob rau hauv uas siab tshaj hauv cov khib nyiab, tab sis qis dua hauv cov khoom lag luam.

Txoj kev ua kom muaj txiaj ntsig yog ua tiav ntawm cov chaw ua haujlwm, nyob ib sab ntawm cov roob khib nyiab maj mam loj tuaj.

Recycling khib nyiab

Txawm hais tias lawv tsis muaj txiaj ntsig zoo, cov pob zeb no tuaj yeem siv rau hauv kev lag luam thiab kev tsim kho. Yog li, lawv tau siv rau hauv reclamation, hauv kev tsim kho, lawv sau kuv cov haujlwm, tsaug zog ravines. Ntau lub pob zeb pov tseg, yav tas los suav tias tsis tsim nyog, tau pom lawv daim ntawv thov hauv kev lag luam niaj hnub, piv txwv li, Khibiny nepheline. Yav dhau los, thaum tau txais apatite concentrate, nepheline raug xa mus rau khib nyiab, tab sis tam sim no, ua tsaug rau kev tshawb fawb tshawb fawb, nws tau siv ntau hauv kev lag luam. Yog li, cov pob zeb pov tseg, txawm hais tias lawv lub npe qhia, tuaj yeem ua tiav thiab tau txais txiaj ntsig.
