Ilitye le-phosphate libhekisa kwigama eliqhelekileyo leeminerali ze-phosphate ezinokusetyenziswa ngokwezoqoqosho, ikakhulu i-apatite kunye nelitye le-phosphate. I-phosphorus etyheli, i-phosphoric acid, i-phosphide kunye nezinye ii-phosphates zisetyenziswa kwezonyango, ekutyeni, kumatshisi, kwiidayi, kwiswekile, kwiiseramikhi, kukhuselo lwesizwe nakwamanye amacandelo emizi-mveliso.
Iipropati ze-ore kunye nolwakhiwo lwezimbiwa
Kukho malunga neentlobo ezili-120 zeeminerali eziqulethe i-phosphorus ezaziwayo kwindalo, kodwa njengeminerali zemizi-mveliso eziqulethe i-phosphorus, ikakhulu ziiminerali ze-phosphate kwi-apatite nakwi-phosphate rock. I-Apatite [Ca5(PO4)3(OH,F)] yiminerali eyinxalenye yayo ephambili yi-calcium phosphate. Inamagama ahlukeneyo ngenxa yezinto ezahlukeneyo eziqulathe kuyo, njenge-fluorine kunye ne-chlorine. Iiminerali eziqhelekileyo eziqulethe i-phosphorus zezi: I-Fluorapatite, i-chloroapatite, i-hydroxyapatite, i-carbon hydroxyapatite, i-carbon hydroxyapatite, i-carbon hydroxyapatite, njl. Umxholo wethiyori we-P2O5 uphakathi kwe-40.91 kunye ne-42.41%. Ii-anions ezongezelelweyo i-F, OH, CO3, kunye ne-O kwi-phosphate rock zinokuthatha indawo enye, kwaye kukho izinto ezininzi ze-isomorphic, ngoko ke ukwakheka kweekhemikhali zeminerali kutshintsha kakhulu.
Ukwakheka kweekhemikhali eziqhelekileyo ze-apatite
- Izinto zekhemikhali 2. UmxholoIindawo zesicelo kunye neemfuno zesalathisoIlitye le-phosphate lisetyenziswa kakhulu njengezinto ezisetyenziswa kwi-phosphorus acid fertilizer kunye nee-phosphorus compounds ezahlukeneyo, kwaye lisetyenziswa kakhulu kwicandelo leekhemikhali, amayeza, izibulali-zinambuzane, ishishini lokukhanya kunye neshishini lezomkhosi.Itekhnoloji yokucubungulaUkuzuza kunye nokuhlanjululwa
Ilitye le-phosphate linokwahlulwa libe yi-siliceous type, i-calcareous type, kunye ne-silicon (calcium)-calcium (silicon type). Iiminerali ezinxulumene nazo ikakhulu 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, njl.njl., indlela ye-flotation yeyona ndlela ibalulekileyo yokuzuza i-apatite.
Inkqubo yetekhnoloji ephambili ibandakanya ikakhulu: inkqubo edibeneyo yokuqubha + ukwahlulahlula ngemagnethi, ukugaya + ukwahlulahlula + inkqubo yokuqubha, ukugaya inqanaba + inkqubo yokwahlulahlula inqanaba, ukurosta + ukugaya + inkqubo yokwahlulahlula.
Indandatho epholisiweyo edibeneyo yamanzi e-oyile kunye ne-vertical gradient separator ephezulu yemagnethi
Ukucutshungulwa kweePhosphate Compounds zePhosphate Fertilizers
Ukwenziwa kwezichumiso ze-phosphate kukuguqula iiminerali ze-phosphate zibe zii-phosphates ezifunxwa lula zizityalo ngenkqubo yokuphucula, ubushushu obuphezulu, kunye nokwenziwa. I-Ammonium phosphate sisichumiso esidityanisiweyo esisebenza kakuhle esenziwe nge-phosphoric acid emanzini e-ammonia. I-phosphorus etyheli ifunyanwa ngokufudumeza ilitye le-phosphate elixutywe nesanti ye-quartz kunye ne-coke kwi-1500°C kwisithando sombane. Kukho iindlela ezimbini zokuvelisa i-phosphoric acid: indlela yokukhupha i-sulfuric acid kunye nendlela yokukhupha i-peroxy combustion.
Umzekelo wokuzuza
Ubunzima beentsalela zesinyithi eHebei yi--200 mesh, ebalelwa kwi-63.29%, umxholo we-TFe iyonke yesinyithi yi-6.95%, kwaye umxholo we-P2O5 yi-6.89%. Isinyithi ikakhulu yi-oxide yesinyithi efana ne-limonite, i-silicate yesinyithi kunye ne-magnetite ngendlela ye-inclusions eqhubekayo; iiminerali ezine-phosphorus ikakhulu yi-apatite, iiminerali ze-gangue yi-quartz, i-feldspar, i-calcite, njl. Idityaniswe ngokusondeleyo neeminerali ze-phosphorus. Injongo yovavanyo kukukhetha iiminerali ezahlukeneyo ezine-iron ngokwahlukana kwemagnethi, kwaye i-apatite ityebiswe kwiintsalela ze-magnetic separation.
Ngokweempawu zeesampuli, inkqubo yokuphucula imiselwa ngolu hlobo lulandelayo: i-ore eluhlaza ekhethiweyo – i-mesh engama-200 enobuncinci be-63.29%, yenziwe ibe yi-slurry enoxinzelelo lwe-30%, kwaye i-iron magnetic eqhubekayo ikhethwa yi-CTB4000GS weak magnetic field, kwaye i-tailings ikhethwa yi-vertical ring 0.5T weak Magnetic iron oxide kunye ne-iron silicate minerals.
Ukuhamba kwenkqubo yovavanyo lokususwa kwesinyithi sokwahlulwa kwemagnethi kwimisila yesinyithi equlethe iphosphorus
Iintsila zesinyithi ezine-phosphorus eziqulathe isinyithi ziye zadlula kwinkqubo yokususa isinyithi ngokurhabaxa kunye nokutshayelwa kabini, kwaye iimveliso zesinyithi ezifanelekileyo azikwazanga ukukhethwa kwizinto ezinomtsalane. Umxholo we-phosphorus kwi-phosphorus coarse concentrate unyuswe ukusuka kwi-6.89% ukuya kwi-10.12%, kwaye izinga lokubuyisa i-phosphorus laliyi-79.54%. %, izinga lokususa isinyithi laliyi-75.83%. Kuvavanyo lokuthelekisa amandla ahlukeneyo entsimi yeLihuan 0.4T, 0.6T kunye ne-0.8T, kwafunyaniswa ukuba amandla aphantsi entsimi yeLihuan 0.4T abangele isinyithi esininzi kwi-phosphorus coarse necociweyo, kwaye amandla aphezulu entsimi ye-0.8T abangele ukulahleka kwe-phosphorus kwizinto ezinomtsalane. Inkulu. Ukukhethwa kweemeko ezifanelekileyo zokwahlulwa kwemagnethi kuluncedo ukuphucula isalathisi sokuzuza sokusebenza kwe-flotation kwelitye le-phosphate elisezantsi.
