Ntau Yam Koj Yuav Tsum Paub Txog Kub Cyanidation

Kev siv cyanidation kub yog ib txoj kev rho kub los ntawm kev siv cyanide ua tus neeg sawv cev rau kev lim. Vim nws muaj kev txawj ntse, kev lim sai, thiab kev siv tau zoo rau cov hlau, txoj kev siv cyanidation tseem yog ib txoj hauv kev rho kub tseem ceeb tam sim no. Hauv cov txheej txheem cyanidation kub , txhua kauj ruam yuav tsum tau tswj kom ntseeg tau tias muaj txiaj ntsig zoo rau kev lag luam thaum txo qhov hnyav ntawm cov khoom siv thiab kev nqis peev.

1. Aeration thiab Cyanide Ntxiv

Tom qab sib tsoo, cyanide yog ntxiv rau lub pulp kom yaj kub thiab tsim cov hlau complexes. Cov qauv tshuaj tiv thaiv yog raws li nram no: 4Au + 8NaCN + O2 + 2H2O → 4NaAu(CN)2 + 4NaOH. Raws li tau pom los ntawm cov qauv saum toj no, cov pa oxygen yuav tsum tau nyob rau hauv cov txheej txheem ntawm leaching kub. Yog li ntawd, nyob rau hauv industrial ntau lawm, lub leaching tank yuav tsum tau aerated. Lub aeration siab feem ntau yog hais txog 1 kg, thiab aeration ntim ib feeb rau txhua cubic meter ntawm slurry yog ntau tshaj 0.002 m³.

2. Ntxiv kev tiv thaiv Alkali

Txhawm rau kom ntseeg tau tias cov ntsiab lus ntawm cyanide nyob rau hauv cov ntaub so ntswg, zam kev ua qias tuaj ib puag ncig, thiab tiv thaiv kev tsim cov tshuaj lom hydrogen cyanide (HCN) roj, alkali yuav tsum tau ntxiv rau hauv lub tank leaching kom muaj pH siab ntawm cov pulp. Txiv qaub los yog txiv qaub kua txiv feem ntau siv rau hauv kev tsim khoom, thiab qee zaum NaOH ntxiv rau kev hloov kho ntxiv.

3. Txhim kho Slurry Suspension

Cov txheej txheem kub cyanidation muaj qee yam yuav tsum tau ua rau kev ua haujlwm ntawm lub leaching agitation tank. Nrog kev siv hluav taws xob tsawg, cov khoom ntawm monomer-sib cais lossis nthuav tawm kub hauv cov tawv nqaij yuav tsum tsis txhob tso rau hauv lub tank. Lub pulp, cyanide, txiv qaub, thiab huab cua yuav tsum tau sib xyaw ua ke hauv lub tank kom ncav cuag lub xeev ncua. Lub slurry concentration nyob rau hauv txhua feem ntawm lub tank yuav tsum zoo ib yam, thiab yuav tsum tsis muaj stratification raws li qhov tob ntawm lub tank, thiab particle loj faib yuav tsum uniform.

4. Tswj kom tsim nyog Slurry Concentration

Thaum qhov ceev ntawm cov ore kub yog 2.65 - 2.8. Qhov dav dav leaching pulp concentration yog 40 - 45%. Thaum qhov ceev ntawm flotation concentrate yog 3 - 3.5. Qhov dav dav leaching concentration yog 30 - 40%. Feem ntau, cov ntaub ntawv uas muaj qhov zoo tsawg dua 200 mesh account rau 80 - 95%.

5. Txo qhov hnav thiab suab nrov ntawm cov khoom txav

Txhawm rau txo qhov hnav ntawm cov agitator thiab ua kom nws lub neej kev pab cuam, feem ntau impellers nyob rau hauv industrial ntau lawm yog roj hmab-lined. Kev xaiv ntawm cov khoom siv kis tau tus mob yuav tsum tau ua tib zoo xyuas kom muaj kev sib kis tau zoo thiab tsis muaj suab nrov.

6. Txo cov pa roj carbon hnav

Txoj kev Carbon -in-pulp ntxiv cov pa roj carbon rau hauv lub tank adsorption kom nqus tau kub. Yog tias lub zog agitation ntawm lub tank leaching muaj zog dhau, cov pa roj carbon yuav raug zom thiab poob. Yog tias lub zog agitation tsis muaj zog, cov av nkos yuav tsim tawm. Yog li ntawd, thaum tswj cov pulp hauv lub xeev suspended, ntawm ib sab tes, nws yog qhov tsim nyog los xaiv cov pa roj carbon siab-hardness rau kev tsim khoom, thiab ntawm qhov tod tes, nws yog qhov tsim nyog los txo qhov kev sib hloov ceev ntawm lub impeller kom txo qhov poob ntawm pulp, carbon, thiab lub zog nkag ntawm lub tank adsorption agitation.

7. Kev txiav txim siab tsim nyog

Tam sim no, lub peev xwm ua tau zoo ntawm cov nroj tsuag kub kub cyanidation ntau ntawm ntau kaum ntawm tons txog kaum txhiab tons hauv ib hnub. Qhov loj dua qhov muaj peev xwm ntau lawm, qhov loj ntawm thaj chaw cog, thiab qhov loj dua cov cuab yeej specifications thiab peev. Txhua tus tswv ntawm lub mine yuav tsum txiav txim siab txog qhov tsim nyog cov khoom tsim nyog raws li qhov xwm txheej tiag tiag.

8. Txo cov khoom hnyav thiab kev nqis peev

Thaum xaiv lub tank leaching, ntawm ib sab, cov txheej txheem leaching yuav tsum tau ua kom muaj zog thiab txuag hluav taws xob, thiab tib lub sijhawm, cov khoom siv sib kis yuav tsum muaj cov hneev taw me me thiab lub teeb yuag. Thaum lub peev xwm, qhov siab ntawm cov pulp, thiab lub sij hawm leaching yog txiav txim siab, tus naj npawb ntawm cov tso tsheb hlau luam tuaj yeem txiav txim siab. Txawm li cas los xij, cov lus qhia tshwj xeeb ntawm leaching tso tsheb hlau luam yuav tsum tsim nyog rau cov nroj tsuag muaj peev xwm. Thaum tsim 500t / d kub cyanidation cog, yog tias siv lub φ3.5X3.5m leaching tank, cov khoom siv yuav tsum tau nce ntxiv, nce kev nqis peev. Yog li ntawd, tsuas yog nrog cov khoom siv lub teeb thiab lub peev xwm tsim nyog tuaj yeem txo qis kev tsim kho kev lag luam.
