Kub txiaj

Kub txiaj

Cov peev txheej kub refractory feem ntau tuaj yeem muab faib ua peb hom:
Thawj hom yog siab arsenic, carbon, thiab sulfur hom kub ore.Hauv hom no, cov ntsiab lus arsenic ntau dua 3%, cov ntsiab lus carbon yog 1-2%, thiab cov ntsiab lus sulfur yog 5-6%.Siv cov txheej txheem cyanide kub rho tawm, qhov kub leaching tus nqi yog feem ntau 20-50%, thiab ntau npaum li cas ntawm Na2CN tau noj.Thaum enriched los ntawm flotation thev naus laus zis, txawm hais tias qib kub siab dua tuaj yeem tau txais, cov concentrate muaj qib siab ntawm cov teeb meem xws li arsenic, carbon, thiab antimony.Nws yuav muaj kev cuam tshuam rau cov kauj ruam tom ntej ntawm cov txheej txheem kub rho tawm.

Hom thib ob yog kub-muaj ore uas kub yog qhwv hauv gangue minerals thiab teeb meem impurities nyob rau hauv zoo hais thiab microscopic daim ntawv.Hauv hom no, cov ntsiab lus hlau sulfide yog me me, txog 1-2%, thiab yog embedded nyob rau hauv gangue minerals.Cov khoom kub zoo hauv cov muaju suav nrog 20-30%.Cov txheej txheem cyanide extraction los yog flotation enrichment txoj kev yog siv los rho cov kub, tab sis cov kub rov qab yog tsawg heev.

Hom thib peb yog kub ore nrog kev sib raug zoo ntawm kub, arsenic thiab sulfur.Nws cov yam ntxwv yog tias arsenic thiab sulfur yog cov khoom tseem ceeb ntawm cov khoom kub, thiab cov ntsiab lus arsenic yog nruab nrab.Cov kub leaching Performance index ntawm hom ore no siv ib qho txheej txheem cyanide kub rho tawm yog qhov tsawg.Yog hais tias kub yog enriched los ntawm flotation, ib tug ntau dua rov qab tus nqi yuav tau, tab sis nws yog ib qho nyuaj rau muag vim hais tias nws muaj ntau arsenic.

tshuab mining

kev xaiv tshuaj

1. Kub mineralization thiab sib cais

Txoj kev siv tshuaj lom neeg ntawm cov mines kub feem ntau suav nrog txoj kev dej sov thiab txoj kev cyanide.Txoj kev sib xyaw yog qhov qub thiab haum rau coarse-grained ib qho kub.Txawm li cas los xij, nws yog qhov qias neeg thiab tau maj mam hloov los ntawm kev txawj ntse.Muaj ob txoj kev cyanidation, stirring cyanidation thiab percolation cyanidation.

2. Cov khoom siv tshuaj thiab kub xaiv

Cov txheej txheem tshuaj yog siv los xaiv cov ore kub, feem ntau yog cov txheej txheem cua.Cov khoom siv muaj xws li zinc hmoov pauv khoom, leaching stirring tank, thiab lwm yam. Lub zinc hmoov hloov khoom yog ib qho cuab yeej uas hloov kub av nkos los ntawm cov leachate nrog zinc hmoov.

Lub leaching stirring tank yog ib qho khoom siv rau nplawm cov slurry.Thaum cov ore particle loj yog qis dua 200 mesh thiab cov kev daws teeb meem yog qis dua 45%, kev ncua tuaj yeem tsim los ua kom cov concentration ntawm cov kub yaj hauv lub tank adsorption thiab ceev lub sij hawm leaching.
