Oxygen yog cov txheej txheem reagent hauv kub cyanidation ntau dua li cov roj siv hluav taws xob. Hauv cov pa roj carbon-hauv-Leach (CIL) thiab Carbon-hauv-Pulp (CIP) cov nroj tsuag, cov pa oxygen yaj ncaj qha cuam tshuam rau kub dissolution kinetics, siv cyanide, slurry oxidation tej yam kev mob, thiab tag nrho cov kev ua tau zoo.
Raws li ore throughput nce, oxygen xav tau nyob rau hauv lub leaching Circuit Court kuj nce. Ntau qhov kev ua haujlwm mining nyob rau hauv thaj chaw deb ib txwm nyob ntawm kev xa cov pa oxygen ua kua lossis lub tog raj kheej thauj mus los kom tswj tau cov pa oxygen. Txawm li cas los xij, kev thauj mus los deb, kev nkag mus tau yooj yim, huab cua huab cua, thiab kev tswj cov khoom lag luam tuaj yeem ua rau nce nqi khiav lag luam thiab qhia txog kev pheej hmoo ntawm cov khoom siv.
Txhawm rau txo qis kev vam khom rau kev thauj mus los ntawm cov pa oxygen sab nraud, cov neeg ua haujlwm mining tau nce ntxiv rau ntawm -site PSA oxygen tsim tshuab. NEWTEK PSA Oxygen Plant hloov cov cua compressed rau hauv cov pa oxygen ntawm qhov chaw mine thiab tsis tu ncua muab cov pa oxygen rau cov txheej txheem leaching yam tsis muaj kev cia siab rau cov khoom xa tawm tsis tu ncua.
Kab lus no piav qhia txog yuav ua li cas PSA oxygen thev naus laus zis txhawb nqa CIL thiab CIP kev ua haujlwm, yuav ua li cas lub kaw lus ua ke nrog cov txheej txheem mining, thiab vim li cas cov nroj tsuag ntim cov pa oxygen tau dhau los ua ib qho kev daws teeb meem rau tej thaj chaw deb mining.
Yog vim li cas Oxygen thiaj yuav tsum tau nyob rau hauv CIL thiab CIP kub rov qab
Oxygen Txhawb Kub Dissolution Reactions
Kub cyanidation yuav tsum tau sodium cyanide thiab yaj oxygen. Cov tshuaj tiv thaiv leaching tuaj yeem sawv cev los ntawm Elsner Equation:
Cov tshuaj tiv thaiv no qhia tau hais tias cov pa oxygen ncaj qha koom rau hauv kev sib cais ntawm cov hlau kub. Thaum yaj cov pa oxygen txo qis, cov tshuaj tiv thaiv yuav qeeb txawm tias cyanide concentration tseem tsis hloov. Vim li no, kub ua cov nroj tsuag niaj hnub saib xyuas:
· Dissolved oxygen concentration
· Cyanide concentration
· Slurry pH
· Lub sijhawm khaws cia
· Slurry ceev
kom ruaj khov leaching tej yam kev mob.
Kev txhaj tshuaj yog feem ntau tsis txaus
Feem ntau cov leaching circuits pib cia siab rau compressed cua txhaj. Txawm li cas los xij, huab cua hauv huab cua tsuas muaj: 21% oxygen thiab 78% nitrogen. Raws li slurry ceev nce thiab ore throughput nce, oxygen hloov los ntawm huab cua yuav tsis zoo.
Cov kev sib tw ib txwm muaj xws li:
· Cov pa oxygen qeeb qeeb
· Txwv tsis pub oxygen hloov efficiency
· Ntau lub sij hawm khaws cia
· Txo cov pa oxygen concentration hauv cov tso tsheb hlau luam hauv qab
Kev txhaj tshuaj PSA- tsim cov pa oxygen tso cai rau cov neeg ua haujlwm kom nce cov pa oxygen ntau ntxiv yam tsis muaj roj ntau ntxiv.
Oxygen Demand nce nrog throughput
Raws li lub peev xwm milling nthuav dav, kev siv oxygen nce ntxiv. Piv txwv li, cov nroj tsuag kub ua 1,500 TPD ore yuav xav tau cov pa oxygen tsawg dua li cov nroj tsuag ua 5,000 TPD ore. Cov pa oxygen yuav tsum tau cuam tshuam los ntawm: ore mineralogy, sulfide cov ntsiab lus, leaching nyob rau lub sij hawm, thiab yaj lub hom phiaj oxygen. Vim tias kev siv cov pa oxygen yog txheej txheem- nyob ntawm, lub peev xwm tsim cov pa oxygen yuav tsum tau txiav txim siab los ntawm cov ntaub ntawv tsim cov hlau tsis yog kwv yees los ntawm cov nroj tsuag loj ib leeg.
Yuav ua li cas NEWTEK PSA Oxygen Plant Ua haujlwm
