Itshe le-phosphate libhekisela egameni elivamile lamaminerali e-phosphate angasetshenziswa ngokwezomnotho, ikakhulukazi idwala le-apatite ne-phosphate.I-phosphorus ephuzi, i-phosphoric acid, i-phosphide namanye ama-phosphates asetshenziswa kwezokwelapha, ukudla, umentshisi, odayi, ushukela, izitsha zobumba, ukuvikela izwe kanye neminye imikhakha yezimboni.
Izakhiwo ze-Ore kanye nesakhiwo samaminerali
Kunezinhlobo ezingaba ngu-120 zamaminerali aqukethe i-phosphorus aziwa endalweni, kodwa njengamaminerali aqukethe i-phosphorus ikakhulukazi amaminerali e-phosphate edwaleni le-apatite ne-phosphate.I-Apatite [Ca5(PO4)3(OH,F)] iyimineral ingxenye yayo eyinhloko i-calcium phosphate.Inamagama ahlukene ngenxa yezakhi ezahlukene eziqukethe, njenge-fluorine ne-chlorine.Amaminerali avamile aqukethe i-phosphorus yilezi: I-Fluorapatite, i-chloroapatite, i-hydroxyapatite, i-carbonapatite, i-fluorocarbon apatite, i-carbon hydroxyapatite, njll. Okuqukethwe kwethiyori kwe-P2O5 kuphakathi kuka-40.91 no-42.41%.Ama-anion engeziwe F, OH, CO3, kanye no-O edwaleni le-phosphate angashintshana, futhi kunezingxenye eziningi ze-isomorphic, ngakho ukwakheka kwamakhemikhali amaminerali kuyashintsha kakhulu.
Ukwakheka kwamakhemikhali okujwayelekile kwe-apatite
- Izingxenye zamakhemikhali 2.OkuqukethweIzindawo zokufaka izicelo kanye nezidingo zenkombaI-Phosphate rock isetshenziswa kakhulu njengezinto ezingavuthiwe zomanyolo we-phosphoric acid kanye nezinhlanganisela ezahlukahlukene ze-phosphorus, futhi isetshenziswa kabanzi emkhakheni wemboni yamakhemikhali, umuthi, izibulala-zinambuzane, imboni yokukhanya kanye nemboni yezempi.Ukucubungula UbuchwephesheUkuhlomula nokuhlanzwa
Itshe le-phosphate lingahlukaniswa libe uhlobo lwe-siliceous, uhlobo lwe-calcareous, kanye nohlobo lwe-silicon (calcium) -calcium (silicon).Amaminerali ahambisanayo ikakhulukazi i-quartz, i-flint, i-opal, i-calcite, i-feldspar, i-mica, i-limestone, i-dolomite, umhlaba ongavamile., i-magnetite, i-ilmenite, i-limonite, njll., indlela ye-flotation iyindlela ebaluleke kakhulu yokuzuza ye-apatite.
Inqubo yezobuchwepheshe yesimiso ikakhulukazi ihlanganisa: i-flotation + ukuhlukaniswa kwamagnetic inqubo ehlanganisiwe, ukugaya + ukuhlukanisa + inqubo ye-flotation, ukugaya esiteji + inqubo yokuhlukaniswa kwesiteji, ukugazinga + ukugaya + inqubo yokuhlukanisa.
Ukupholisa okuyinhlanganisela yamanzi kawoyela iringi ethe mpo mpo isihlukanisi kazibuthe
Ukucutshungulwa Kwezinhlanganisela Ze-Phosphate Zomanyolo we-Phosphate
Ukwenziwa komanyolo we-phosphate ukuguqula amaminerali e-phosphate abe ama-phosphates adonswa kalula izitshalo ngenqubo yokuzuza, izinga lokushisa eliphezulu, kanye nokuhlanganiswa.I-Ammonium phosphate ingumanyolo osebenza kahle kakhulu ohlanganisiwe owenziwe nge-phosphoric acid emanzini ammonia.I-phosphorus ephuzi itholakala ngokushisisa idwala le-phosphate elixutshwe nesihlabathi se-quartz kanye ne-coke ku-1500°C esithandweni sikagesi.Kunezindlela ezimbili zokukhiqiza ze-phosphoric acid: indlela yokukhipha i-sulfuric acid kanye nendlela yokumuncwa kwe-peroxy combustion.
Isibonelo sokuhlomula
Ukucoleka kwezinsimbi zensimbi e-Hebei kungama-mesh angu-200, okubalelwa ku-63.29%, ingqikithi ye-iron TFe okuqukethwe ngu-6.95%, kanti okuqukethwe kwe-P2O5 kungu-6.89%.I-iron ngokuyinhloko i-iron oxide efana ne-limonite, i-iron silicate ne-magnetite ngendlela yokufakwa okuqhubekayo;amaminerali aqukethe i-phosphorus ikakhulukazi i-apatite, amaminerali e-ganggue yi-quartz, i-feldspar, i-calcite, njll. Ihlanganiswe eduze namaminerali e-phosphorus.Inhloso yokuhlolwa ukukhetha amaminerali ahlukahlukene ane-iron ngokuhlukaniswa kazibuthe, futhi i-apatite inothiswe kumsila wokuhlukanisa kazibuthe.
Ngokusho kwezakhiwo zamasampula, inqubo yokuzuza inqunywa ngale ndlela elandelayo: insimbi eluhlaza ekhethiwe - i-200 mesh ene-fineness ye-63.29%, yenziwa i-slurry ene-concentration ye-30%, futhi i-iron magnetic eqhubekayo ikhethiwe. nge-CTB4000GS inkambu kazibuthe ebuthakathaka, futhi izinsalela zikhethwa yindandatho eqondile engu-0.5T ebuthakathaka I-Magnetic iron oxide namaminerali e-iron silicate.
Ukugeleza kwenqubo yokuhlolwa kokukhishwa kwensimbi kokuhlukaniswa kukazibuthe kwemisila yensimbi ene-phosphorus
Izinsalela zensimbi ye-phosphorus ezine-iron zenze inqubo yokukhipha insimbi yokumahhadla okukodwa kanye nokushanela kabili, futhi imikhiqizo yokugxilisa insimbi efanelekile ayikwazanga ukukhethwa kokusebenza kazibuthe.Okuqukethwe kwe-phosphorus ku-coarse concentrate ye-phosphorus inyusiwe isuka ku-6.89% yaya ku-10.12%, futhi izinga lokutholwa kwe-phosphorus libe ngama-79.54%.%, izinga lokususa insimbi lalingu-75.83%.Esivivinyweni sokuqhathanisa samandla ahlukene wensimu ye-Lihuan 0.4T, 0.6T kanye ne-0.8T, kwatholakala ukuthi amandla ensimu ephansi ye-Lihuan 0.4T abangele insimbi eningi ku-phosphorus emahhadla futhi ecwengiwe, namandla ensimu aphezulu angu-0.8 T ibangele ukulahleka kwe-phosphorus ezintweni kazibuthe.Okukhulu.Ukukhethwa kwezimo ezifanele zokuhlukaniswa kazibuthe kunenzuzo ukuthuthukisa inkomba yenzuzo yokusebenza kwe-flotation yetshe eliphansi le-phosphate.
