Idwala le-phosphate libhekisela egameni elijwayelekile lamaminerali e-phosphate angasetshenziswa ngokwezomnotho, ikakhulukazi i-apatite kanye nedwala le-phosphate. I-phosphorus ephuzi, i-phosphoric acid, i-phosphide kanye nezinye i-phosphates zisetshenziswa kwezokwelapha, ekudleni, kuma-matches, kumadayi, kushukela, ezintweni zobumba, ekuvikeleni kwezwe nakwamanye amasimu ezimboni.
Izakhiwo Zensimbi Eyigugu kanye Nesakhiwo Sezimbiwa
Kunezinhlobo ezingaba ngu-120 zamaminerali aqukethe i-phosphorus aziwa emvelweni, kodwa njengoba amaminerali ezimboni aqukethe i-phosphorus, ikakhulukazi amaminerali e-phosphate edwaleni le-apatite nasedwaleni le-phosphate. I-Apatite [Ca5(PO4)3(OH,F)] iyiminerali engxenye yayo eyinhloko yi-calcium phosphate. Inamagama ahlukene ngenxa yezinto ezahlukene equkethe, njenge-fluorine ne-chlorine. Amaminerali avamile aqukethe i-phosphorus yilawa: I-Fluorapatite, i-chloroapatite, i-hydroxyapatite, i-carbonapatite, i-fluorocarbon apatite, i-carbon hydroxyapatite, njll. Okuqukethwe kwe-P2O5 kuphakathi kuka-40.91 no-42.41%. Ama-anion engeziwe i-F, OH, CO3, kanye ne-O edwaleni le-phosphate angangena esikhundleni somunye nomunye, futhi kunezingxenye eziningi ze-isomorphic, ngakho-ke ukwakheka kwamakhemikhali kwale mineral kushintsha kakhulu.
Ukwakheka kwamakhemikhali okuvamile kwe-apatite
- Izakhi zamakhemikhali 2. OkuqukethweIzindawo zohlelo lokusebenza kanye nezidingo zenkombaIdwala le-phosphate lisetshenziswa kakhulu njengezinto zokusetshenziswa zomanyolo we-phosphoric acid kanye namakhemikhali ahlukahlukene e-phosphorus, futhi lisetshenziswa kabanzi emikhakheni yezimboni zamakhemikhali, ezokwelapha, ezibulala-zinambuzane, embonini elula kanye nasembonini yezempi.Ubuchwepheshe BokucubungulaUkuzuza kanye nokuhlanzwa
Idwala le-phosphate lingahlukaniswa ngohlobo lwe-siliceous, uhlobo lwe-calcareous, kanye nohlobo lwe-silicon (calcium)-calcium (silicon). Amaminerali ahlobene nawo ikakhulukazi yi-quartz, i-flint, i-opal, i-calcite, i-feldspar, i-mica, i-limestone, i-dolomite, i-rare earth. , i-magnetite, i-ilmenite, i-limonite, njll., indlela ye-flotation iyindlela ebaluleke kakhulu yokuzuza i-apatite.
Inqubo yezobuchwepheshe eyinhloko ihlanganisa ikakhulukazi: inqubo ehlanganisiwe yokuntanta + ukuhlukaniswa kwamagnetic, inqubo yokugaya + ukuhlukaniswa + inqubo yokuntanta, inqubo yokugaya esiteji + inqubo yokuhlukanisa esiteji, ukuyosa + ukugaya + inqubo yokuhlukanisa.
Indandatho eqondile epholisa amanzi ahlanganisiwe e-oyili-indandatho ehlukanisiwe enamandla amakhulu kagesi
Ukucutshungulwa Kwamakhemikhali E-Phosphate Omanyolo We-Phosphate
Ukukhiqizwa komanyolo we-phosphate kuwukuguqula amaminerali e-phosphate abe ama-phosphate amuncwa kalula yizitshalo ngenqubo yokuzuza, izinga lokushisa eliphezulu, kanye nokuhlanganiswa. I-Ammonium phosphate iwumanyolo ohlanganisiwe osebenza kahle kakhulu owenziwe nge-phosphoric acid emanzini e-ammonia. I-phosphorus ephuzi itholakala ngokushisa 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.
Isibonelo senzuzo
Ubuncane be-iron tailings eHebei buyi-mesh engu-200, okubalwa ku-63.29%, okuqukethwe kwe-TFe yensimbi iyonke kungu-6.95%, kanti okuqukethwe kwe-P2O5 kungu-6.89%. I-iron ikakhulukazi i-iron oxide efana ne-limonite, i-iron silicate kanye ne-magnetite ngendlela yokufakwa okuqhubekayo; amaminerali aqukethe i-phosphorus ikakhulukazi yi-apatite, amaminerali e-gangue yi-quartz, i-feldspar, i-calcite, njll. Ihlanganiswe eduze kakhulu namaminerali e-phosphorus. Inhloso yokuhlolwa ukukhetha amaminerali ahlukahlukene aphethe insimbi ngokuhlukaniswa kwamagnetic, kanti i-apatite icebile ezingxenyeni zokuhlukanisa kwamagnetic.
Ngokwezakhiwo zamasampula, inqubo yokuzuza inqunywa kanje: i-ore eluhlaza ekhethiwe - i-mesh engu-200 enobuncane obungu-63.29%, yenziwa ibe yi-slurry enokuqukethwe okungu-30%, kanti i-iron magnetic eqhubekayo ikhethwa yi-CTB4000GS weak magnetic field, kanti i-tailings ikhethwa yi-vertical ring 0.5T weak Magnetic iron oxide kanye ne-iron silicate minerals.
Ukugeleza kwenqubo kokuhlolwa kokususwa kwensimbi okuhlukaniswe ngemagnethi kwemisila yensimbi equkethe i-phosphorus
Izinsimbi zensimbi eziqukethe i-phosphorus zidlule enkambisweni yokususa insimbi eyodwa yokugoqa kanye nenye yokushanela kabili, futhi imikhiqizo yokugxila kwensimbi efanelekile ayikwazanga ukukhethwa ezintweni ezisebenza ngogesi. Okuqukethwe kwe-phosphorus ku-phosphorus coarse concentrate kwandiswe kusuka ku-6.89% kuya ku-10.12%, kanti izinga lokubuyisa i-phosphorus lalingu-79.54%. %, izinga lokususa insimbi lalingu-75.83%. Ekuhlolweni kokuqhathanisa amandla ensimu ahlukene e-Lihuan 0.4T, 0.6T kanye no-0.8T, kwatholakala ukuthi amandla ensimu aphansi e-Lihuan 0.4T abangele insimbi eningi kakhulu ku-phosphorus coarse futhi ecwengisisiwe, kanti amandla ensimu aphezulu angu-0.8T abangele ukulahlekelwa kwe-phosphorus ezintweni ezisebenza ngogesi. Okukhulu. Ukukhethwa kwezimo zokuhlukanisa amandla kagesi ezifanele kuyasiza ekuthuthukiseni inkomba yokuzuza kokusebenza kwe-flotation kwedwala le-phosphate elingezansi.
