Thallium ore sorting: kev tswj kev nyab xeeb thiab cov nqi rov qab rau cov hlau uas muaj tshuaj lom heev

Thallium yog cov hlau tsis tshua muaj siab heev, uas muaj cov ntawv thov tshwj xeeb hauv ob peb lub siab - thev naus laus zis xws li cov khoom siv kho qhov muag infrared, iav tshwj xeeb, thiab cov khoom siv kho mob. Txawm li cas los xij, kev pheej hmoo ntawm ib puag ncig thiab kev noj qab haus huv yog nws lub hom phiaj tseem ceeb ntawm kev tswj hwm. Thallium tsis tshua muaj tshwm sim raws li kev ywj pheej ntawm cov pob zeb hauv av thiab feem ntau tshwm sim raws li qhov teeb meem cuam tshuam hauv qee cov sulfide ores. Intelligent sorting technology muab ib qho kev txiav - ntug kev daws teeb meem uas muaj kev nyab xeeb, ua haujlwm tau zoo, thiab ua raws li cov cai tswj hwm thiab xaiv rov ua dua tshiab ntawm cov khoom muaj kev pheej hmoo siab.
Cov yam ntxwv thiab cov teeb meem tseem ceeb ntawm thallium ntxhia cov peev txheej
Kev lag luam thiab ib puag ncig qhov tseem ceeb ntawm thallium feem ntau yog los ntawm nws cov koom haum thiab tshuaj lom:
Tag nrho cov khoom muaj txiaj ntsig thiab muaj kev phom sij: Thallium feem ntau tshwm sim ua ib qho impurity hauv pyrite, sphalerite, galena, thiab qee cov poov tshuaj ntsev deposits. Nws cov zaub mov ywj pheej (xws li thallium) yog qhov tsawg heev. Thaum lub sij hawm mining thiab cov txheej txheem tau txais txiaj ntsig, thallium tuaj yeem nkag mus rau hauv lub cev dej thiab plua plav, ua rau muaj kev phom sij loj rau ib puag ncig thiab kev noj qab haus huv.
Cov ntsiab lus tsawg heev thiab kev sib cais nyuaj: Hauv cov ore raw, qib ntawm thallium feem ntau yog nyob rau hauv qhov chaw ib lab ntau yam. Nyob rau hauv cov txheej txheem ib txwm, nws yog dispersed nyob rau hauv cov khoom tseem ceeb mloog zoo los yog tailings thiab tsis muaj kev lag luam zoo ntawm lub cev sib cais txoj kev. Nws tsuas yog tso siab rau qhov kawg ntawm cov txheej txheem metallurgical rau kev sib cais lossis kev kho kom ruaj khov, uas yog kim thiab ua rau muaj kev pheej hmoo ntawm cov pa phem thib ob.
Cov kev txwv nruj dua: Cov qauv emission rau cov tshuaj lom xws li thallium tau dhau los ua nruj dua thoob ntiaj teb, yuam cov mines thiab smelters kom ntxiv dag zog rau kev txheeb xyuas, sib cais, thiab tswj cov thallium uas muaj cov khoom siv los ntawm qhov chaw.
Kev siv tshiab ntawm kev txawj ntse sorting technology
Cov kev txheeb xyuas ntse raws li cov khoom siv qib siab thiab cov cuab yeej txheeb xyuas cov ntxhia xws li laser-induced breakdown spectroscopy (LIBS) thiab hyperspectral imaging muab cov cuab yeej tawg rau pem hauv ntej- kawg tswj kev pheej hmoo thiab kev siv peev txheej ntawm thallium uas muaj ore. Cov thev naus laus zis no tuaj yeem ua tiav qhov kev txheeb xyuas meej hauv cov theem ntxhib crushing (10-50mm).
Nws qhov tseem ceeb daim ntawv thov tus nqi yog nyob rau hauv:
Kev txheeb xyuas ntxov thiab kev cais tawm ntawm qhov chaw muaj kev pheej hmoo: Cov tshuab ntse tuaj yeem txheeb xyuas cov sulfide ore blocks nrog cov ntsiab lus siab thallium (xws li thallium nplua nuj pyrite) raws li cov yam ntxwv ntawm lub hauv paus. Kev txheeb xyuas thiab cais tawm cov ntaub ntawv muaj kev pheej hmoo ntawm qhov ua ntej ntawm cov txheej txheem tsim khoom tuaj yeem tiv thaiv thallium los ntawm kev nthuav dav hauv cov txheej txheem qhib tom ntej xws li crushing, sib tsoo, thiab flotation, zoo heev txo cov pa phem rau tag nrho cov txiaj ntsig system (xws li dej ncig thiab tailings) los ntawm kev tswj thiab yooj yim.
Ua kom muaj zog kev coj ua thiab kev pov tseg raws txoj cai: Cov khoom sib cais siab thallium tuaj yeem raug rau hauv nruab nrab thiab kaw kev ua haujlwm tshwj xeeb. Qhov no tsim cov xwm txheej rau ob txoj hauv kev: ib qho yog ua kom me me - nplai thiab siab - kev ua tau zoo ntawm kev taw qhia metallurgical rov qab ntawm cov ntaub ntawv nrog cov nqi rov ua dua; Qhov thib ob yog kom muaj kev nyab xeeb thiab ua raws li kev ruaj ntseg ntawm cov khoom pov tseg uas tsis muaj nqi nyiaj txiag. Ob txoj hauv kev muaj kev nyab xeeb dua thiab tus nqi ntau dua - ua haujlwm zoo dua li cov qauv kev ua haujlwm sib xyaw ua ke.
Txhim kho qhov zoo thiab kev ruaj ntseg ntawm cov khoom tseem ceeb: Rau tooj liab, zinc, txhuas thiab lwm yam hlau tseem ceeb mines, sib cais ores nrog siab thallium cov ntsiab lus ua ntej tuaj yeem pab tsim cov hlau tseem ceeb nrog cov ntsiab lus qis impurity thiab ntau tus phooj ywg ib puag ncig, ua tau raws li kev muag khoom nruj dua, thiab txo thallium cuam tshuam hauv cov txheej txheem smelting thiab cov nqi ib puag ncig tom ntej.
Txhawb nqa kuv qhov kaw thiab kev tswj hwm keeb kwm yav dhau los: Cov cuab yeej no muab kev tshuaj ntsuam xyuas zoo thiab txhim kho txoj hauv kev rau kev soj ntsuam kev nyab xeeb thiab kev tswj xyuas cov pa phem thallium hauv keeb kwm tailings pas dej thiab cov pob zeb pov tseg. Nws tuaj yeem cais cov khoom muaj kev pheej hmoo siab ntawm tus nqi qis rau kev tswj hwm hauv nruab nrab, txo qhov ntev - lub luag haujlwm ib puag ncig.
Kev lag luam Outlook
Niaj hnub no, nrog lub ntiaj teb no ESG (Environmental, Social and Governance) lub moj khaum thiab lub tswv yim ntawm "lub luag haujlwm mining" dhau los ua cov qauv kev lag luam, kev tswj xyuas muaj peev xwm ntawm cov tshuaj lom neeg muaj feem cuam tshuam xws li thallium ncaj qha cuam tshuam rau kev khiav hauj lwm daim ntawv tso cai thiab kev sib raug zoo lub koob npe nrov ntawm cov tuam txhab mining. Kev txheeb xyuas qhov chaw thiab kev pheej hmoo cais tawm muaj peev xwm muab los ntawm cov cuab yeej ntse sorting yog cov thev naus laus zis tseem ceeb kom ua tiav lub hom phiaj no.
Rau cov tuam txhab lag luam uas cuam tshuam nrog cov txheej txheem polymetallic sulfide deposits, kev nqis peev hauv kev sib xyaw ntse sorting tshuab tsis yog tsuas yog kev txhim kho thev naus laus zis, tab sis kuj tseem yog ib qho kev nqis peev tseem ceeb hauv kev tsim kev pheej hmoo tiv thaiv kev muaj peev xwm, ua tiav kev ua raws li ib puag ncig, thiab ua tiav cov luag haujlwm hauv zej zog. Nws cim qhov kev hloov pauv ntawm kev tswj hwm ntawm siab - cov teeb meem cuam tshuam los ntawm tus qauv "kawg ntawm cov yeeb nkab kho" mus rau lub sijhawm tshiab ntawm kev txawj ntse "qhov chaw tiv thaiv thiab kev tswj xyuas meej".
