Phosphate pob zeb hais txog cov ntsiab lus dav dav rau phosphate minerals uas tuaj yeem siv nyiaj txiag, feem ntau yog apatite thiab phosphate pob zeb. Daj phosphorus, phosphoric acid, phosphide thiab lwm yam phosphates yog siv nyob rau hauv kev kho mob, zaub mov, ntais ntawv, dyes, qab zib, ceramics, lub teb chaws tiv thaiv thiab lwm yam kev lag luam teb.
Ore Properties thiab Mineral Structure
Muaj txog 120 hom phosphorus-muaj cov zaub mov paub hauv cov xwm txheej, tab sis raws li phosphorus-muaj cov ntxhia hauv kev lag luam feem ntau yog phosphate minerals hauv apatite thiab phosphate pob zeb. Apatite [Ca5(PO4)3(OH,F)] yog cov ntxhia uas nws lub ntsiab yog calcium phosphate. Nws muaj cov npe sib txawv vim muaj cov ntsiab lus sib txawv, xws li fluorine thiab chlorine. Cov zaub mov uas muaj phosphorus muaj xws li: Fluorapatite, chloroapatite, hydroxyapatite, carbonapatite, fluorocarbon apatite, carbon hydroxyapatite, thiab lwm yam. Cov ntsiab lus theoretical ntawm P2O5 yog nyob nruab nrab ntawm 40.91 thiab 42.41%. Cov anions ntxiv F, OH, CO3, thiab O hauv pob zeb phosphate tuaj yeem hloov tau ib leeg, thiab muaj ntau yam isomorphic, yog li cov tshuaj muaj pes tsawg leeg ntawm cov ntxhia hloov pauv zoo heev.

- Chemical Cheebtsam 2.Cov ntsiab lusCov cheeb tsam ntawm daim ntawv thov thiab qhov ntsuas qhov xav tauPhosphate pob zeb yog siv los ua raw khoom ntawm phosphoric acid chiv thiab ntau yam phosphorus tebchaw, thiab yog dav siv nyob rau hauv kev lag luam tshuaj, tshuaj, tshuaj tua kab, lub teeb kev lag luam thiab tub rog kev lag luam.Kev Siv TshuabKev pab thiab purification
Phosphate pob zeb tuaj yeem muab faib ua siliceous hom, calcareous hom, thiab silicon (calcium)-calcium (silicon) hom. Cov minerals uas txuam nrog feem ntau yog quartz, flint, opal, calcite, feldspar, mica, limestone, dolomite, tsis tshua muaj ntiaj teb. , magnetite, ilmenite, limonite, thiab lwm yam., flotation method yog qhov tseem ceeb tshaj plaws txoj kev pab rau apatite.
Cov txheej txheem thev naus laus zis feem ntau suav nrog: flotation + sib nqus sib nqus ua ke txheej txheem, sib tsoo + kev faib tawm + txheej txheem flotation, theem sib tsoo + txheej txheem sib cais, roasting + digestion + txheej txheem kev faib tawm.

Kev ua ntawm Phosphate Compounds ntawm Phosphate Fertilizers
Phosphate fertilizer manufacturing yog hloov phosphate minerals rau hauv phosphates uas yooj yim absorbed los ntawm cov nroj tsuag los ntawm cov txheej txheem ntawm beneficiation, kub siab, thiab synthesis. Ammonium phosphate yog cov khoom siv ua haujlwm siab ua los ntawm phosphoric acid hauv dej ammonia. Daj phosphorus yog tau los ntawm cua sov phosphate pob zeb tov nrog quartz xuab zeb thiab coke ntawm 1500 ° C nyob rau hauv lub cub hluav taws xob. Muaj ob txoj hauv kev tsim cov phosphoric acid: sulfuric acid extraction method thiab peroxy combustion absorption method.
Piv txwv kev pab
Lub fineness ntawm hlau tailings nyob rau hauv Hebei yog -200 mesh, accounting rau 63.29%, tag nrho cov hlau TFe ntsiab lus yog 6.95%, thiab cov ntsiab lus P2O5 yog 6.89%. Hlau yog tsuas yog hlau oxide xws li limonite, hlau silicate thiab magnetite nyob rau hauv daim ntawv ntawm nruam inclusions; Cov zaub mov uas muaj phosphorus feem ntau yog apatite, gangue cov zaub mov yog quartz, feldspar, calcite, thiab lwm yam. Lub hom phiaj ntawm qhov kev ntsuam xyuas yog xaiv ntau yam hlau-kev coj tus kheej cov zaub mov los ntawm kev sib nqus sib nqus, thiab apatite yog enriched nyob rau hauv cov hlau nplaum sib cais tailings.
Raws li cov khoom ntawm cov qauv, cov txheej txheem ntawm cov txiaj ntsig tau txiav txim siab raws li hauv qab no: cov ore xaiv raw - 200 mesh nrog fineness ntawm 63.29%, yog ua rau slurry nrog ib tug concentration ntawm 30%, thiab nruam hlau nplaum yog xaiv. los ntawm CTB4000GS tsis muaj zog magnetic teb, thiab cov tailings raug xaiv los ntawm lub nplhaib ntsug 0.5T tsis muaj zog hlau nplaum hlau oxide thiab hlau silicate minerals.
Cov txheej txheem khiav ntawm kev sib nqus sib nqus hlau tshem tawm kev sim ntawm phosphorus-muaj hlau tailings
Cov hlau uas muaj phosphorus hlau tailings tau ua tiav cov txheej txheem tshem tawm hlau ntawm ib qho roughing thiab ib qho cheb ob zaug, thiab cov khoom tsim nyog hlau concentrate tsis tuaj yeem xaiv los ntawm cov khoom sib nqus. Cov ntsiab lus phosphorus nyob rau hauv phosphorus coarse concentrate tau nce los ntawm 6.89% mus rau 10.12%, thiab phosphorus rov qab yog 79.54%. %, tus nqi tshem tawm hlau yog 75.83%. Hauv kev sib piv ntawm qhov sib txawv ntawm thaj chaw muaj zog ntawm Lihuan 0.4T, 0.6T thiab 0.8T, nws tau pom tias qhov tsis tshua muaj zog ntawm Lihuan 0.4T ua rau muaj hlau ntau dhau ntawm phosphorus ntxhib thiab ua kom zoo, thiab lub zog siab ntawm 0.8T. T ua rau poob ntawm phosphorus hauv cov khoom sib nqus. Loj. Kev xaiv ntawm qhov tsim nyog sib nqus sib cais yog qhov zoo los txhim kho qhov txiaj ntsig Performance index ntawm flotation kev ua haujlwm ntawm qis phosphate pob zeb.
