Peb Hom Kub Ore Leaching Txheej Txheem

Hauv Cov Txheej Txheem Leaching ntawm cov ntaub ntawv, raws li qhov sib txawv ntawm cov kev taw qhia ntws ntawm cov ntaub ntawv leached thiab cov tshuaj reagents leaching, peb cov txheej txheem leaching tuaj yeem txheeb xyuas tau.

1. Co-tam sim no Leaching

Hauv co - tam sim no leaching, cov ntaub ntawv leached thiab leaching reagents ntws mus rau tib qho kev taw qhia (Daim duab 1). Txoj kev no tuaj yeem tso tawm cov dej xau nrog cov ntsiab lus siab ntawm cov hom phiaj thiab yuav tsum tau siv qis dua ntawm cov leaching reagents. Txawm li cas los, nws leaching ceev yog qeeb. Lub sijhawm leaching ntev dua yog xav tau kom ua tiav qhov siab leaching.

2. Hla - tam sim no Leaching

Nyob rau hauv cross - tam sim no leaching, cov ntaub ntawv leached yog cais leached nrog ob peb feem ntawm cov tshiab leaching reagents. Cov leachate tau los ntawm txhua qhov kev ua haujlwm leaching yog uniformly xa mus rau kev ua haujlwm tom ntej (Daim duab 2). Hla - tam sim no leaching nta ib tug kuj ceev leaching ceev thiab ib tug luv luv leaching lub sij hawm, ua rau ib tug siab leaching tus nqi. Txawm li cas los xij, qhov ntim ntawm cov leachate yog loj, nrog rau siab concentration ntawm residual reagents. Raws li qhov tshwm sim, kev noj cov tshuaj reagents yog qhov tseem ceeb, thiab cov ntsiab lus ntawm lub hom phiaj ntawm cov tshuaj leachate yog qhov tsawg.

3. Counter - Tam sim no Leaching

Nyob rau hauv txee - tam sim no leaching, cov ntaub ntawv leached thiab leaching reagents txav mus rau qhov sib txawv. Ntawd yog, cov ntaub ntawv depleted tom qab ob peb leaching ua hauj lwm los rau hauv kev sib cuag nrog cov leachate tshiab, thaum cov ntaub ntawv thawj leached hu rau leachate (Daim duab 3). Counter - tam sim no leaching tuaj yeem tsim cov leachate nrog cov ntsiab lus siab ntawm lub hom phiaj cov khoom thiab ua kom tag nrho siv cov residual reagents nyob rau hauv cov leachate, yog li txo cov kev noj cov tshuaj leaching. Txawm li cas los xij, nws qhov leaching ceev yog qis dua li ntawm tus ntoo khaub lig - tam sim no leaching. Ntau cov theem leaching ntau dua yuav tsum tau kom tau txais qhov leaching siab.

Percolation tank leaching tuaj yeem txais cov txheej txheem co - tam sim no, hla - tam sim no, lossis counter - tam sim no leaching txheej txheem. Heap leaching thiab nyob rau hauv - situ leaching feem ntau ntiav cov co - tam sim no cyclic leaching txheej txheem. Nruam stirred leaching feem ntau yog siv cov txheej txheem leaching tam sim no. Yog hais tias tus ntoo khaub lig - tam sim no los yog counter - tam sim no leaching yog yuav tsum tau siv, khoom - kua sib cais kev khiav hauj lwm yuav tsum tau ntxiv ntawm txhua theem. Batch - ua haujlwm nplawm leaching feem ntau yog co - tam sim no leaching, tab sis hla - tam sim no lossis txee - tam sim no leaching tuaj yeem siv tau. Txawm li cas los xij, cov khoom sib cais yuav tsum tau ua tom qab txhua qhov kev ua haujlwm leaching, ua rau kev ua haujlwm nyuaj thiab tsis tshua siv hauv kev tsim khoom. Percolation leaching tuaj yeem tau txais cov kua dej ntshiab ncaj qha, thaum lub slurry los ntawm kev sib xyaw leaching yuav tsum tau ua kom tiav - kua sib cais kom tau txais cov kua dej ntshiab los yog dilute slurry uas muaj me me ntawm cov khoom siv rau kev ua haujlwm tom ntej.
