Kab laum Qib CMCRau cov pob zeb hauv ntxhia tau siv nyob rau hauv frotation, sib tsoo, sedimentation conctrtration, pom thiab lwm qhov txuas tseem ceeb hauv kev ua haujlwm hauv ntxhia. Los ntawm kev tswj hwm cov khoom ntawm ore pulp lossis tus cwj pwm ntawm cov zaub mov, yog li qib ua tiav cov txiaj ntsig ntawm kev txhim kho cov qib ntawm mloog zoo. Mineral ua cov qib CMC ua cov luag haujlwm tseem ceeb hauv ntau qhov txuas ntawm cov ua haujlwm hauv cov ntxhia:
1. Kev khawb avCov txheej txheem flotation:Tsuas yog qib CMC ua haujlwmRaws li kev muaj kev ntxhov siab lossis kev tswj hwm
Tsuas yog cov ntxaij vab tshausyog cov txheej txheem tseem ceeb ntawm cov ntxhia ua. Nws lub hom phiaj yog cais cov hom phiaj me me los ntawm cov zaub mov Gangue los ntawm kev nqis tes ua xws li cov neeg sau thiab inhibitors. CMC ua si lub luag haujlwm tseem ceeb hauv kev ua pob tawb, txo cov tub rog ua haujlwm lossis kho cov viscosity ntawm cov orgposity.
1.1. Kab laum Qib CMCtauinhibit gangue minerals thiab txhim kho kev xaiv ntawmkhoom ntawm avkev cais
Yog tias cov zaub mov Gangue (xws li Quartz, Talc, silicate, thiab lwm yam xws li cov hlau thiab cov roj av thiab cov kab mob siab) yuav raug txo kom tsawg. Mining qib CMC tuaj yeem inhibit gangue los ntawm nws tus kheej kev kawm adsorption thiab zaj duab xis- deing khoom:
Adsorption: cov pab pawg carboxyl (- caangu molecule tuaj yeem ua rau cov neeg laib) los ntawm hydogen daim ntawv cog lus los ua cov yeeb yaj kiab hydrophilic.
Therinding cov ntawv txuas ntawm cov neeg sau khoom: Lub Nom Hydrophilic zaj duab xis yuav tiv thaiv cov adsoret ntawm cov neeg ua haujlwm, yog li cov neeg gangeSs, yog li cov neeg ncaws pob ua ke thiab nyob hauv cov slurry es tsis txhob ua npuas.
Cov Kev Siv Raug:
Thaum flotating tooj liab, txhuas thiab zinc sulfide ores, mining qib CMC tuaj yeem Inhibit silicate Gangrue xws li Gangue nkag mus rau hauv lub siab xav;
Thaum floating hlau ore, Mining Qib CMC tuaj yeem ua rau tsis muaj qhov tsis zoo xws li Quartz thiab APATite thiab txhim kho cov qib hlau ua kom zoo.
1.2.Kab laum Qib CMCtauKho cov viscosity ntawm ore pulp thiab txhim kho cov flotation ib puag ncig
Ntau dhau qhov siab slurry viscosity tuaj yeem ua rau tsis ncaj fubble dispersion thiab nrawm fab me me partlet daws, cuam tshuam kev ua kom cov kev ua tau zoo. Carboxymethyl cellu cov khoom thickening tuaj yeem txhim kho cov roj kev ua tau zoo los ntawm kev tswj hwm viscosity. Thaum tsawg tsawg tshuaj, mining qib CMC tuaj yeem tawg cov khoom zoo (xws li av nplaum) hauv slurry) nyob rau hauv lub slurry) nyob rau hauv lub slurry) nyob rau hauv lub slurry) nyob rau agglomeration thiab qhov ua kom muaj kev nce siab hauv viscosity. Ntawm cov kev muaj koob tshuaj ntau, tsuas yog qib CMC tuaj yeem ua rau muaj kev sib cuam tshuam ntawm cov ntxhia thiab lub sijhawm ua haujlwm qeeb ntawm cov ntxhia thiab lub reagent (tshwj xeeb haum rau cov ntxhib flotation).
2. Sib Tsoo Txheej Txheem:Mineral ua qib CMC tuaj yeemsiv raws li akev khawb avDispersant kom txhim kho kev sib tsoo.
Lub hom phiaj ntawm kev sib tsoo yog los tsoo ore rau qhov tsim nyog me me thiab cais cov pob zeb cov pob zeb cov ntxhia. Txawm li cas los xij, cov khoom zoo (tshwj xeeb tshaj yog cov zaub mov sib xyaw) nyiam agglomerate, ua rau "dhau {{2} - burilling sib tsoo equiciencing.
Ntxhia Qib Cakc ua raws li tus neeg tsis txaus siab hauv kev sib tsoo, txhim kho kev sib tsoo ua haujlwm los ntawm nws cov qauv molecular. Nws adsorbs mus rau saum npoo ntawm cov ntxhia cov nplais, cais cov nqi tsis zoo rau lawv thiab tiv thaiv agglomeration los ntawm xws li- Hloov pauv, los ntawm stacer hill cellu cellulose molecular cellule molecular thaiv daim ntawv ib tug, tiv thaiv lub cev, tiv thaiv ib leeg thiab txhim kho cov haujlwm sib tsoo.
Thaum lub sij hawm sib tsoo, mining qib CMC rau cov khoom siv ntxhia uas muaj kev txo qis, ua rau cov khoom loj me me ntawm cov khoom siv hauv av ntau dua thiab tsis txhob muaj "kev thaj av" tshwm sim. Nyob rau tib lub sijhawm, nws txo cov kev sib tsoo ntawm cov xov xwm sib tsoo (thiab thaum kawg tuaj yeem siv hluav taws xob ntau, thiab tsim cov kev ua kom haum xeeb rau kev ua kom huv si.
3. Tsuas yog siv CMC yog sivRaws li cov flocculant lossis dispersant nyob rau hauv cov sedimentation thiab concentration txheej txheem kom nrawm tau cov khoom khov kho {{}}} kua sib cais.
Cov slurry uas tsim tawm thaum cov txheej txheem pob zeb hauv pob zeb (xws li flotation tailings thiab sib tsoo hauv cov tawv nqaij- cov khoom siv dej sib cais, thiab txo cov khoom siv dej, thiab txo cov khoom siv dej, thiab txo cov khoom siv dej, thiab txo cov khoom siv dej, thiab txo cov khoom ntim ntawm cov tailings. Tsuas yog qib carboxymethyl cellulose plays ib tug xov tooj ntawm cov luag haujlwm hauv tus txheej txheem no.
3.1. Kev khawb avCMC sivRaws li cov flocculant kom nrawm nrawm ntawm sedimentation ntawm cov khoom zoo
Cov nplais zoo (xws li cov av nkos) hauv cov txheej txheem pob zeb hauv cov txheej txheem yog yooj yim rau hauv dej vim lawv qhov loj me me, thiab yog qhov nyuaj rau kev sib haum xeeb. Tsuas yog qib CMC tuaj yeem txhawb kev flocculation los ntawm nws cov yam ntxwv:
Adsorption Bridging: Mining Qib CMC molcular chains tuaj yeem adsorb ntau cov lus yog agle ua ke nyob rau hauv cov flocs loj, yog li nce cov bedimentation tus nqi;
Kev nruab nrab ntawm kev them nqi: Tsuas yog CMC tuaj yeem pub tus nqi zoo nyob rau ntawm cov hlau thiab manganese cov hlau (xws li cov hlau uas tsis tshua muaj zog), txo qhov kev quab yuam ntawm cov lus ntawm cov khoom, thiab txhawb aggomeration.
Daim ntawv thov kev xaiv ntawm Mining Qib CMC rau cov ntxhia ua hauv cov txheej txheem sedimentation:
Tailings thickening pond: Mining carbookyhly cellulose tuaj yeem nrawm nrawm (txo cov dej ntshiab) (rov qab ua dua tshiab);
Mas nrho cov concentration: tsuas cmc tuaj yeem nce cov kev xav ntawm thiab npaj rau kev lim dej kom ua kom pom kev thiab lub cev qhuav dej.
3.2. Muaj qib miningCMC sivRaws li akev khibHauv kev ua lag luam hauv ntxhia ua rau tiv thaiv coarse hais los ntawm kev nthuav dav dhau.
Hauv qee kis (xws li tso tsheb hlau luam hauv nruab nrab uas muaj kev sib tw slurry kev sib tw tau sai dhau sai, nws yuav ua rau tsis ncaj slurry convenation. Hauv qhov no, tsawg tshuaj ntawm tsuas yog qib carboxymethyl cellulose tuaj yeem tawg cov ntxhib thiab tiv thaiv sai sai los ntawm kev ruaj khov.
4. MINING CMCyog sivRaws li cov kev pab lim hauv cov txheej txheem kev ua haujlwm los txhim kho kev ua kom muaj kev ua tiav
Pom yog ib qho ntawm cov kauj ruam kawg hauv kev ua tiav ntxhia. Nws lub hom phiaj yog rau lub cev qhuav dej kom muaj slurry (mloog) kom tau txais cov roj ncuav mog qab zib (kua) thiab lim (kua). Ntxhia qib Carboxymethyl cellulose tuaj yeem siv los ua cov kev pab lim los ua kom tiav cov txheej txheem kev pom zoo. Nws cov haujlwm tseem ceeb muaj raws li hauv qab no:
Txo cov lim lim daim ntaub: Cov ntxhia ua yeeb yam ntawm cov npoo ntawm cov khoom zoo kom tiv thaiv lawv los ntawm clogging daim ntaub lim;
Txhim kho cov lim ncuav mog qab zib cov qauv: Mining Qib CMC tuaj yeem ua rau lub lim ncuav mog qab zib thiab cov qauv hluav taws xob tsis kam thiab nce kev lim dej nrawm;
Txhim kho cov duab qhia meej: Mining qib CMC Absagebs zoo hais, txo cov teeb meem tshem tawm hauv cov khoom siv tau rov siv dua.
Cov kev siv tsis raug ntawm cov mining cmc hauv kev lim dej:
Thaum lub sij hawm cov txheej txheem pom ntawm hlau ee mloog zoo,Mineral Chamasymethyl Cellulosetuaj yeem txo cov dej noo cov ntsiab lus ntawm cov lim ncuav mog qab zib thiab txhim kho kev thauj mus los thiab tso tseg kev ruaj ntseg ntawm cov hlau ore mloog zoo; Tailing pom kev tuaj yeem nrawm ntawm lub cev qhuav dej ntawm cov tailings thiab txo cov kev cia siab ntawm cov tailings.
Lub ntsiab
Tsuas yog muaj qib CMC ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm cov ntxhia pob zeb, hauv plab zom mov (agressing gangles), kev ua kom nrawm nrawm), ua kom pom kev pab), thiab lwm yam txuas. Tsuas yog qib CMC kawg txhim kho cov pob zeb hauv av, mloog zoo qib thiab cov peev txheej hloov kho. Nws yog ib qho kev ua yeeb yam massals.
