Cov Neeg Pab Nyiaj Kub

Cov Neeg Pab Nyiaj Kub

Refractory cov peev txheej kub feem ntau yuav muab faib ua peb hom loj:
Thawj hom yog siab arsenic, carbon, thiab sulfur hom kub ore. Hauv hom no, cov ntsiab lus arsenic yog ntau dua 3%, cov pa roj carbon yog 1-2%, thiab cov Sulfur cov ntsiab lus yog 5-6%. Siv cov txheej txheem cyanide cov roj ntau ntxiv, tus nqi xauj hauv kub yog feem ntau yog 20-50%, thiab cov nyiaj ntau ntawm NA2CN tau noj. Thaum enriched los ntawm flotation technology, txawm hais tias qib kub siab dua tuaj yeem tau, qhov siab dua muaj cov khoom muaj teeb meem siab xws li arsenic, carbon, thiab tshuaj pleev ib yam. Nws yuav muaj kev cuam tshuam rau cov kauj ruam tom ntej ntawm cov txheej txheem kub ntxiv.

Qhov thib ob hom yog kub-muaj cov ees uas kub yog qhwv hauv Gangue zaub mov thiab teeb meem impurities nyob rau hauv cov khoom zoo thiab cov ntawv me me. Nyob rau hauv hom no, cov ntaub hlau sulfide cov ntsiab lus yog me me, li 1-2%, thiab yog kos rau hauv Gangue Minerals. Cov nyiaj nplua nuj nyob rau hauv lub muaju account rau 20-30%. Cov kev sib xyaw ua ke ntau dua los yog cov txheej txheem flotation yog siv los rho tawm kub, tab sis cov nyiaj rov qab kub heev.

Qhov thib peb yog kub ore nrog kev sib raug zoo ntawm kub, arsenic thiab leej faj. Nws cov yam ntxwv yog cov arsenic uas yog cov neeg sab nrauv yog cov khoom siv tseem ceeb ntawm kub, thiab cov ntsiab lus arsenic yog nruab nrab. Qhov kub ceev cov ntsuas ntawm hom ore no siv ib tus txheej txheem cyanide kub extraction yog tsawg. Yog tias kub yog enriched los ntawm flotation, ib qho kev rov qab siab dua tuaj yeem tau txais, tab sis nws yog qhov nyuaj muag vim tias nws muaj cov arsenic ntau dhau.

Kev Siv Tshuab Mining

Kev Xaiv Xaiv

1. KUB Mineralization thiab Kev Sib Cais

Cov kev siv tshuaj lom neeg tau txais txiaj ntsig ntawm cov mines kub feem ntau yog suav nrog txoj kev dej sov thiab Cyanide txoj kev. Cov txheej txheem sib xyaw yog tus qub thiab haum rau cov ntxhib-grained ib kub. Txawm li cas los xij, nws yog qhov tseeb polluting thiab tau hloov maj mam hloov los ntawm kev txawj ntse. Muaj ob txoj hauv kev Cyanidation, nplawm Cyanidation thiab Percolation Cyanidation.

2. Tshuaj lom neeg thiab khoom siv kub

Cov qauv tshuaj siv tau siv los xaiv cov khoom siv kub, feem ntau yog cov huab cua txoj kev. Cov khoom siv siv suav nrog zinc hmoov sib pauv ntaus ntawv, ntshiv stampring tank, thiab lwm yam hloov chaw uas hloov av kub los ntawm kev ua kom zoo nkauj nrog zinc.

Cov noob ntshiv nplawm tank yog ib qho khoom siv rau nplawm cov slurry. Thaum lub ore particle loj yog qis dua 200 mesh thiab cov kev daws teeb meem yog qis dua ntawm 45% tuaj yeem tsim kom muaj kev xav txog kev tshaj tawm hauv lub sijhawm adsorption thiab nrawm lub sijhawm lav.
