Kev txawj ntse sorting ntawm kub ore: ua ntej - kev hloov pauv rau kev ua kom zoo dua cov hlau zoo

Kev ua haujlwm ntawm cov ore kub tau dhau los ua ib qho kev hloov pauv uas tau tsav los ntawm kev siv thev naus laus zis. Raws li kev tswj tau yooj yim cov peev txheej kub thoob ntiaj teb tau nce zuj zus lawm, cov tuam txhab mining tau tig mus rau ntau dua thiab qib qis dua. Nyob rau hauv qhov kev hloov pauv no, kev txawj ntse sorting raws li kev siv thev naus laus zis zoo tshaj plaws muab kev lag luam muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo rau kev kho kub mine pretreatment.
Kev lag luam cov nyom thiab kev txheeb xyuas cov hauv kev
Kev lag luam kub ua haujlwm tsuas yog nyob ntawm lub zog siv cov txheej txheem xws li crushing, sib tsoo, thiab oxidation (carbon leaching lossis flotation). Qhov kev sib tw tseem ceeb nyob hauv:
Kev lag luam kev lag luam ntawm cov qib qis heev: Ntau lub lag luam kub mines muaj qib ntawm tsuas yog 1-2 grams ib tuj, uas txhais tau hais tias rau txhua ooj kub rho tawm, txog 30 tons ntawm ore yuav tsum tau ua tiav.
Cov nqi khiav lag luam siab, tshwj xeeb tshaj yog nyob rau hauv kev sib tsoo (uas suav txog ntau dua 50% ntawm tag nrho cov kev siv hluav taws xob ntawm cov nroj tsuag tau txais txiaj ntsig) thiab kev siv tshuaj reagent.
Kev cuam tshuam ntawm "robbing kub" cov zaub mov: arsenic, antimony, carbonaceous minerals, thiab lwm yam. ua rau muaj kev nyuaj siab thiab nqi ntawm kev ua.
Daim ntawv thov ntawm Intelligent Sorting Technology
Intelligent sorting technology, tshwj xeeb tshaj yog cov tshuab ua ke nrog X-ray kis tau tus mob (XRT) thiab hyperspectral imaging, muaj peev xwm ua tau zoo ua ntej sorting nyob rau hauv lub ntxhib crushing theem (feem ntau yog 10-100mm).
Nws cov txiaj ntsig tseem ceeb tau tshwm sim hauv:
Cov pob zeb pov tseg ua ntej ua rau kev lag luam txhim kho kev lag luam: Los ntawm kev txheeb xyuas lub sijhawm tiag tiag, lub kaw lus tuaj yeem txheeb xyuas thiab tshem tawm cov pob zeb pov tseg uas tsis muaj kub lossis qib qis heev. Ntau tus neeg mob tau pom tias cov cuab yeej no tuaj yeem ua tiav qhov kev pov tseg pov tseg ntawm 30% -70% nyob rau hauv qhov chaw ntawm kev tswj tau kub poob (feem ntau<10%). This directly reduces the amount of material entering the high cost grinding and leaching process by half, significantly lowers the processing cost per unit of ore, and lowers the breakeven grade of the project.
Targeted processing and process optimization: Intelligent sorting tuaj yeem cais cov ores rau ntau hom, xws li:
High qib ore blocks: tuaj yeem ncaj qha nkag mus rau qhov nrawm nrawm.
Ore muaj cov ntxhia kub: tuaj yeem coj mus rau kev ua haujlwm siab.
Pob zeb khib nyiab: muab pov tseg ncaj qha lossis siv los ua cov khoom siv hauv tsev.
Qhov "kev faib ua cov txheej txheem" ​​no zoo heev txhim kho tus nqi rov qab tag nrho thiab cov txheej txheem kev ruaj ntseg.
Ua kom qis -qib thiab cov peev txheej nyuaj: Cov thev naus laus zis no ua rau nws muaj peev xwm ua rau kev lag luam rho tawm cov qib marginal ores uas yav dhau los suav tias yog pov tseg, thiab muab txoj hauv kev zoo rau kev ua cov kub seem hauv cov pas dej keeb kwm yav dhau los, txuas ntxiv kuv lub neej.
Txhawb nqa kev lag luam mining kom ruaj khov: Los ntawm kev txo qis emissions ntawm qhov chaw, kev siv hluav taws xob, kev siv dej, kev siv tshuaj lom neeg, thiab kev tsim cov tailings ib chav tsev ntawm kub ntau lawm tau raug txo ncaj qha, uas ua rau txo qis cov pa roj carbon hneev taw thiab muaj zog txhawb rau ESG cov hom phiaj.
Technical Applicability thiab Prospects
Kev txawj ntse sorting yog tshwj xeeb tshaj yog tsim nyog rau deposits qhov twg kub muaj nyob rau hauv daim ntawv ntawm ntxhib hais los yog pom kub, ore lub cev muaj ib tug loj npaum li cas ntawm cov pov tseg pob zeb, thiab complex ores muaj minerals uas muaj kev cuam tshuam tsis zoo rau cov txheej txheem tom ntej.
Tau ntsib nrog ob qhov kev nyuaj siab ntawm kev nce nqi hluav taws xob thiab kev ua kom nruj ib puag ncig, kev xaiv ntse ntse tau hloov pauv los ntawm "kev xaiv thev naus laus zis" mus rau cov cuab yeej tseem ceeb rau cov phiaj xwm kub mining kom ua tiav cov nqi txo thiab txhim kho kev ua haujlwm, txhim kho kev ruaj ntseg, thiab ntxiv dag zog rau ib puag ncig kev ua haujlwm. Rau kev txiav txim siab- cov neeg tsim cov phiaj xwm tshiab lossis kho dua tshiab, kev sib koom ua ke cov kev txheeb xyuas ntse nyob rau hauv pem hauv ntej- kawg yog qhov peev txheej tseem ceeb los txhim kho kev lag luam kev lag luam thiab kev ruaj khov ntawm txoj haujlwm.
