Kev txawj ntse sorting ntawm tin ore: ib qho tseem ceeb thev naus laus zis rau kev txhim kho kev ua tau zoo thiab cov peev txheej muaj nqis

Tin, raws li ib qho tseem ceeb ntawm kev lag luam hlau, plays lub luag haujlwm tseem ceeb hauv cov khoom siv hluav taws xob, tin plated steel daim hlau, tshuaj lom neeg thiab hlau. Nrog rau kev txhim kho txuas ntxiv ntawm kev lag luam hluav taws xob thoob ntiaj teb thiab kev txhawb nqa ntawm kev lag luam ntsuab ncig, qhov kev thov kom muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo ntawm cov khoom siv tin yog nce zuj zus ib hnub. Nyob rau hauv cov ntsiab lus no, ntse sorting cov kev daws teeb meem raws li kev soj ntsuam cov cuab yeej ua tau zoo yog coj cov kev tsim kho tshiab thiab kev ua kom zoo rau cov nqi ua ntej - ua cov tin ore.
Tin ore cov peev txheej thiab cov teeb meem kev lag luam
Lub ntsiab kev lag luam ntawm tin yog cassiterite, uas feem ntau coexists nrog ntau yam gangue minerals xws li quartz, feldspar, mica, pyrite, thiab lwm yam., tsim complex mineral deposits. Ib txwm tin ore beneficiation hnyav heev nyob rau hauv lub ntiajteb txawj nqus sib cais txheej txheem (xws li jigs thiab shakers), uas yog rhiab heev rau particle loj thiab muaj zog noj. Qhov teeb meem tseem ceeb ntawm kev lag luam tam sim no yog:
Qib ntawm cov ore qub tseem poob qis: qib siab - qib thiab yooj yim tau txais txiaj ntsig tin ore cov peev txheej tau nce zuj zus, thiab cov phiaj xwm tsuas tau hloov mus rau qib qis - qib thiab cov khoom siv sib xyaw ua ke.
Cov nqi ua haujlwm siab: Cov txheej txheem ib txwm xav tau crushing, sib tsoo, thiab rov xaiv cov khoom loj ntawm cov qis-qib cov ore raw, ua rau muaj hluav taws xob loj, tsis tshua muaj nqi rov qab zoo- cov nplej cassiterite, thiab poob loj.
Environmental pressure: Qhov loj ntawm cov tailings tsim los ntawm kev ua cov ore loj heev ua rau muaj teeb meem rau kev tswj hwm ib puag ncig thiab av reclamation.
Txoj Kev Thov Kev Txawj Ntse Xim Xaiv Technology
Nyob rau hauv teb rau cov ntsiab lus mob saum toj no, ntse xim xaiv technology muab ib tug npaum thiab qhuav tov rau lub pre enrichment ntawm tin ore. Cov thev naus laus zis no tuaj yeem ua tau tiag tiag -lub sijhawm hauv online sorting cov ntaub ntawv tom qab ntxhib crushing ntawm ores (feem ntau nyob rau hauv cov particle loj ntawm 10-50mm).
Technical zoo thiab cov txiaj ntsig tseem ceeb:
Ua ntej pov tseg thiab txhim kho qib kev xaiv: Qhov kev xaiv xim ntse ntse tuaj yeem txheeb xyuas qhov sib txawv ntawm cov xim thiab spectral reflectance yam ntxwv ntawm cassiterite (feem ntau yog xim av, xim av, dub, thiab lwm yam) thiab feem ntau lub teeb xim gangue (xws li quartz, feldspar). Los ntawm kev sib cais ntau ntawm cov pob zeb pov tseg ua ntej, qib pub nkag mus rau tom qab rov- cov txheej txheem xaiv tsa tuaj yeem txhim kho tau zoo, thiab qee zaum cov pov tseg pov tseg tuaj yeem ncav cuag ntau dua 40%.
Qhov tseem ceeb txo cov nqi khiav lag luam: Ua ntej muab pov tseg pob zeb ncaj qha txo cov peev txheej ntawm kev sib tsoo thiab cov khoom sib nqus sib cais, txuag txog li 30% -50% ntawm kev siv hluav taws xob (hluav taws xob) thiab khoom siv (dej, tshuaj), thiab txo cov nqi kho tailings.
Txhim kho qhov kev siv tau zoo ntawm cov peev txheej: Cov thev naus laus zis no ua rau nws muaj peev xwm ua rau kev lag luam mine qis -qib ore lub cev, txheej txheem nyuaj symbiotic ores, thiab rov qab cassiterite los ntawm keeb kwm tailings, muaj txiaj ntsig rau kev pab cuam lub neej ntawm mines.
Txhawb nqa ntsuab thiab ruaj khov mining: qhuav sorting tshuab txuag dej thiab txo cov khoom pov tseg los ntawm qhov chaw, pab cov tuam txhab mining ua kom tiav ib puag ncig kev ua tau zoo thiab ESG cov hom phiaj.
Kev lag luam Outlook
Tau ntsib nrog ob lub zog tsav tsheb ntawm qhov tsis txaus ntawm cov peev txheej tin thiab kev xav tau ntawm kev lag luam, cov neeg ua haujlwm mining tau nquag nrhiav kev tsim kho thev naus laus zis los xyuas kom meej cov khoom siv thiab txhim kho kev ua haujlwm zoo. Kev koom ua ke cov kev txheeb xyuas ntse nyob rau hauv pem hauv ntej- kawg ntawm cov txheej txheem tin ore tau txais txiaj ntsig tau dhau los ua ib lub tswv yim tseem ceeb los txhim kho qhov kev ua tau zoo ntawm kev lag luam thiab daws cov teeb meem ntawm qib qis - cov peev txheej. Cov thev naus laus zis no tsis yog tsuas yog lub cuab yeej rau kev ua kom zoo dua qub, tab sis kuj yog ib qho tseem ceeb rau kev tsav tsheb thoob ntiaj teb tin mining kev lag luam mus rau kev txawj ntse, ua tau zoo, thiab kev coj noj coj ua.
