Cov anions ntxiv F, OH, CO3, thiab O hauv pob zeb phosphate tuaj yeem hloov ib leeg, thiab muaj ntau yam khoom isomorphic, yog li cov tshuaj lom neeg ntawm cov zaub mov hloov pauv ntau heev.
Cov tshuaj lom neeg ib txwm muaj ntawm apatite
- Cov Cheebtsam Tshuaj 2. Cov Ntsiab LusCov cheeb tsam thov thiab cov kev cai ntawm cov ntsuasPob zeb phosphate feem ntau yog siv ua cov khoom siv raw ntawm phosphoric acid chiv thiab ntau yam phosphorus sib xyaw, thiab siv dav hauv kev lag luam tshuaj lom neeg, tshuaj, tshuaj tua kab, kev lag luam lub teeb thiab kev lag luam tub rog.Kev Siv Tshuab Ua HaujlwmKev pab thiab kev ntxuav
Pob zeb phosphate muaj peev xwm muab faib ua hom siliceous, hom calcareous, thiab hom silicon (calcium)-calcium (silicon). Cov zaub mov cuam tshuam feem ntau yog quartz, flint, opal, calcite, feldspar, mica, limestone, dolomite, lub ntiaj teb tsis tshua muaj. , magnetite, ilmenite, limonite, thiab lwm yam., txoj kev flotation yog txoj kev pabcuam tseem ceeb tshaj plaws rau apatite.
Cov txheej txheem thev naus laus zis tseem ceeb suav nrog: kev sib xyaw ua ke + kev sib cais sib nqus, kev sib tsoo + kev faib tawm + kev sib xyaw ua ke, kev sib tsoo theem + kev sib cais theem, kev ci + kev zom zaub mov + kev faib tawm.

Kev Ua Cov Phosphate Compounds ntawm Phosphate Chiv
Kev tsim cov chiv phosphate yog hloov cov zaub mov phosphate mus rau hauv phosphates uas cov nroj tsuag yooj yim nqus tau los ntawm cov txheej txheem ntawm kev ua kom zoo, kub siab, thiab kev sib xyaw. Ammonium phosphate yog cov chiv ua haujlwm siab ua los ntawm phosphoric acid hauv dej ammonia. phosphorus daj tau los ntawm kev ua kom sov pob zeb phosphate sib xyaw nrog xuab zeb quartz thiab coke ntawm 1500 ° C hauv lub cub hluav taws xob. Muaj ob txoj hauv kev tsim cov phosphoric acid: txoj kev rho tawm sulfuric acid thiab txoj kev nqus peroxy.
Piv txwv txog kev pab cuam
Qhov zoo ntawm cov hlau tailings hauv Hebei yog -200 mesh, suav txog 63.29%, tag nrho cov hlau TFe cov ntsiab lus yog 6.95%, thiab cov ntsiab lus P2O5 yog 6.89%. Hlau feem ntau yog hlau oxide xws li limonite, hlau silicate thiab magnetite hauv daim ntawv ntawm kev sib xyaw ua ke; cov zaub mov uas muaj phosphorus feem ntau yog apatite, cov zaub mov gangue yog quartz, feldspar, calcite, thiab lwm yam. Nws yog sib xyaw ua ke nrog cov zaub mov phosphorus. Lub hom phiaj ntawm qhov kev xeem yog xaiv ntau yam zaub mov uas muaj hlau los ntawm kev sib cais sib nqus, thiab apatite yog nplua nuj nyob rau hauv cov hlau sib cais sib nqus.
Raws li cov khoom ntawm cov qauv, cov txheej txheem ntawm kev ua kom zoo yog txiav txim siab raws li hauv qab no: cov hlau nyoos xaiv - 200 mesh nrog qhov zoo ntawm 63.29%, yog ua rau hauv cov slurry nrog qhov concentration ntawm 30%, thiab cov hlau sib nqus txuas ntxiv yog xaiv los ntawm CTB4000GS lub zog sib nqus tsis muaj zog, thiab cov tailings yog xaiv los ntawm lub nplhaib ntsug 0.5T tsis muaj zog Magnetic hlau oxide thiab hlau silicate minerals.
Cov txheej txheem ntws ntawm kev sib cais hlau sib nqus tshem tawm kev sim ntawm cov hlau uas muaj phosphorus
Cov hlau uas muaj phosphorus tau dhau los ntawm 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 siv sib nqus. Cov ntsiab lus phosphorus hauv phosphorus coarse concentrate tau nce ntxiv los ntawm 6.89% mus rau 10.12%, thiab phosphorus rov qab tus nqi yog 79.54%. %, tus nqi tshem tawm hlau yog 75.83%. Hauv kev sib piv ntawm cov zog sib txawv ntawm Lihuan 0.4T, 0.6T thiab 0.8T, nws tau pom tias lub zog qis ntawm Lihuan 0.4T ua rau muaj hlau ntau dhau hauv phosphorus coarse thiab refined, thiab lub zog siab ntawm 0.8T ua rau poob ntawm phosphorus hauv cov khoom sib nqus. Loj. Kev xaiv cov xwm txheej sib cais sib nqus tsim nyog yog qhov zoo los txhim kho cov txiaj ntsig ntawm kev ua haujlwm flotation ntawm cov pob zeb phosphate qis dua.
