Ua ke cov yam ntxwv ntawm cov tungsten ore dub thiab dawb tungsten ore beneficiation, tag nrho cov txheej txheem khoom, xaiv, txheej txheem, tsis, thiab tiav configuration, peb muab rau koj nrog ib tug ua tiav thiab ncauj lus kom ntxaws daim ntawv teev cov tungsten ore beneficiation khoom (ib tug dav ntawm - site tov rau tungsten mines nyob rau hauv Jiangxi).
1, Cov ntsiab lus tseem ceeb ntawm tungsten ore tau txais txiaj ntsig
Dub tungsten ore (tungsten manganese hlau ore): feem ntau yog raws li kev sib cais ntawm lub ntiajteb txawj nqus, nrog rau qhov tseem ceeb ntawm kev sib tsoo theem + ntau-theem lub ntiajteb txawj nqus sib cais, txo qis tshaj crushing, siab rov qab tus nqi, tsis muaj tshuaj lom neeg, thiab tus nqi qis.
Scheelite (calcium tungsten ore): flotation yog txoj hauv kev tseem ceeb, cov khoom ntxhib tuaj yeem ua ntej ntxiv los ntawm kev xaiv, cov khoom zoo tuaj yeem ua tiav, thiab kev xaiv tshuaj yuav tsum tau tshem tawm cov calcium gangue.
Cov txheej txheem dav dav: crushing thiab tshuaj ntsuam → sib tsoo thiab muab qhab nia → xaiv ua ntej / rov xaiv → flotation (scheelite) → sib nqus sib nqus rau kev tshem tawm impurity → concentration thiab lub cev qhuav dej.
2, Ua kom tiav cov txheej txheem xaiv tungsten rau tag nrho cov txheej txheem (cov lus piav qhia ntxaws los ntawm theem)
(1) Crushing thiab tshuaj ntsuam system (raw ore pretreatment)

2) Kev xaiv cov khoom siv pov tseg ua ntej (lub zog tseem ceeb-txuag rau tungsten ore)
Coarse grained block ore (10-100mm) yog qhov tseem ceeb rau kev xaiv ua ntej, nrog ntau tshaj 70% ntawm cov pob zeb pov tseg ua ntej, txo cov nqi sib tsoo.
X-ray ntse sorting tshuab (photoelectric beneficiation tshuab): AI paub, tsis siv neeg sorting block ore, nyiam rau niaj hnub loj - nplai tungsten ore.
Tes xaiv platform: yooj yim xaiv ntxhib rau cov mines me.
Hnyav nruab nrab sorting tshuab: Siab pov tseg pob zeb tus nqi mining batch dumping.
3) Sib tsoo thiab grading system (mineral monomer dissociation)
tungsten ore yog nquag mus crushing (tshwj xeeb tshaj yog dub tungsten), yog li qhov tseem ceeb yuav tsum tau muab rau cov pas nrig mills thiab theem sib tsoo, ua ke nrog kaw - voj kev faib tawm.
Qws grinder (nyiam dua rau dub tungsten)
Hlau sib tsoo, xaiv sib tsoo, zoo heev txo cov tungsten ore tshaj crushing thiab nplua av nkos, thiab tseem ceeb rau rov qab los ntawm ntxhib tungsten hais.
Pob zeb (dawb tungsten / zoo sib tsoo / ob-theem sib tsoo)
Pob Zeb
Daim phiaj ntub dej / hom dej ntws, kaw- sib tsoo Circuit Court, sib tsoo kom zoo ntawm -200 mesh kom tau raws li qhov yuav tsum tau muaj flotation.
Spiral classifier/hydrocyclone
Tsim ib lub voj voog kaw nrog lub grinder, muab cov xuab zeb rov qab, tswj kev sib tsoo zoo, thiab desliming; Kev sib tsoo zoo ntawm tungsten dawb feem ntau yog siv los ntawm hydraulic cyclones.
4) Cov khoom siv rov xaiv (dub tungsten ore core, dawb tungsten coarse particle ua ntej enrichment)
Siv qhov sib txawv ntawm tungsten ceev (7.1 ~ 7.5g / cm ³) thiab gangue ceev, nws tsis yog - tshuaj lom, ib puag ncig tus phooj ywg, thiab tus nqi- zoo.
1. Coarse particle reselection (2-20mm)
Sawtooth yoj jigs
Kev xaiv ntxhib thiab ntu ntu ntuav, nrog lub peev xwm ua haujlwm loj, tuaj yeem rov qab cov ntxhib dub tungsten hais thiab txhim kho qib kev xaiv. Nws yog thawj re- khoom siv xaiv tsa rau cov tungsten ore dub.
2. Qhov nruab nrab qhov hnyav xaiv (0.03 ~ 2mm)
kauv chute
Tsis muaj hwj chim, tsis tshua muaj nqi khiav lag luam, loj- nplai xaiv ntxhib thiab ua kom muaj zog, tshem tawm sai ntawm cov gangue loj, haum rau cov xuab zeb tungsten thiab nruab nrab grain loj ntawm cov ore raw.
3. Fine particle / slurry rov qab (0.037-0.0037mm)
Centrifugal beneficiation tshuab (STLB hom)
Kev rov ua dua tshiab tshwj xeeb zoo-cov tungsten ore av nkos uas nyuaj rau xaiv ntawm lub shaker tuaj yeem ua rau tus nqi rov qab los ntawm qhov ntxiv 10% mus rau 15%, uas yog qhov tseem ceeb rau tungsten tailings rov qab.
4. Xaiv purification (universal rau txhua qhov ntau thiab tsawg, cov khoom tseem ceeb rau tungsten concentrate)
6S co rooj (tungsten ore txheem xaiv)
Qhov kev txheeb xyuas qhov tseeb tshaj plaws yog ua tiav los ntawm kev xaiv cov tub ntxhais ntawm nruab nrab thiab nplua -tungsten cov nplej, nrog rau kev kho mob stroke, zaus, thiab cov dej ntim, thaum kawg ua kom tsim nyog siab - qib tungsten concentrate (WO ∝ Ntau dua lossis sib npaug li 65%); Txheej Txheem: Ib qho ntxhib, ob qhov zoo, thiab peb qhov kev tshuaj ntsuam.
5) Cov khoom siv flotation (scheelite core, scheelite coexisting ore)
Fine grained scheelite tsis tuaj yeem raug xaiv thiab rov qab los, tso siab rau ntawm flotation; Ua ntej desulfurize (sulfide ore), ces ntab dawb tungsten, thiab kub kom xaiv thiab tshem tawm calcium gangue.
XCF / KYF inflatable flotation tshuab: cov cuab yeej tseem ceeb rau kev xaiv ntxhib, xaiv xaiv, thiab xaiv zoo ntawm scheelite.
Sib tov thoob: slurry mixing, tshuaj sib tov (sodium carbonate, dej iav, oleic acid / sodium oleate collector).
Txheej txheem: Thawj ntab sulfide ore (desulfurization) → ntxhib xaiv ntawm scheelite → siab - kub concentrated slurry xaiv los daws qhov cuam tshuam ntawm calcium uas muaj gangue xws li calcite thiab fluorite.
