Ilitye lePhosphate libhekisa kwigama eliqhelekileyo leminerali yephosphate enokuthi isetyenziswe ngokwezoqoqosho, ikakhulu i-apatite kunye nelitye le-phosphate.Iphosphoric etyheli, iphosphoric acid, iphosfide kunye nezinye iiphosphates zisetyenziswa kwezonyango, ukutya, imatshisi, idayi, iswekile, iiseramikhi, ukhuselo lwelizwe kunye namanye amashishini.
Iipropati zentsimbi kunye noLwakhiwo lweziMbiwa
Kukho malunga ne-120 yeentlobo zeeminerali ezine-phosphorus ezaziwa kwindalo, kodwa njenge-phosphorus-equlathe iiminerali zamashishini ubukhulu becala ziiminerali ze-phosphate kwi-apatite kunye ne-phosphate rock.I-Apatite [Ca5(PO4)3(OH,F)] yiminerali eyona nxalenye yayo iphambili yicalcium phosphate.Inamagama ahlukeneyo ngenxa yezinto ezahlukeneyo eziquletheyo, ezifana ne-fluorine kunye ne-chlorine.Amaminerali aqhelekileyo aqukethe i-phosphorus: I-Fluorapatite, i-chloroapatite, i-hydroxyapatite, i-carbonapatite, i-fluorocarbon apatite, i-carbon hydroxyapatite, njl. Umxholo wethiyori we-P2O5 uphakathi kwe-40.91 kunye ne-42.41%.I-anion eyongezelelweyo F, OH, CO3, kunye ne-O kwilitye le-phosphate inokutshintsha enye kwenye, kwaye kukho ezininzi iinqununu ze-isomorphic, ngoko ke ukubunjwa kweekhemikhali zeminerali zitshintsha kakhulu.
Ukwakhiwa kweekhemikhali eziqhelekileyo ze-apatite
- Amacandelo emichiza 2.UmxholoIindawo zesicelo kunye neemfuno zesalathisoIlitye lePhosphate lisetyenziswa ikakhulu njengesichumiso se-asidi ye-phosphoric kunye neekhompawundi ezahlukeneyo ze-phosphorus, kwaye isetyenziswa kakhulu kwiinkalo zoshishino lwemichiza, amayeza, i-pesticide, imboni yokukhanya kunye noshishino lomkhosi.ITekhnoloji yoLungisoUkuxhamla kunye nokuhlanjululwa
Ilitye lePhosphate linokohlulwa libe luhlobo lwe-siliceous, uhlobo lwe-calcareous, kunye nesilicon (calcium) -calcium (silicon) uhlobo.Iiminerali ezihambelanayo ikakhulu ziyi-quartz, i-flint, i-opal, i-calcite, i-feldspar, i-mica, i-limestone, i-dolomite, umhlaba onqabileyo., imagnetite, iilmenite, i-limonite, njl. njl., indlela yokudada yeyona ndlela ibalulekileyo ye-apatite.
Inkqubo yethekhnoloji yomgaqo ikakhulu ibandakanya: ukudada + ukwahlula kwamagnetic inkqubo edityanisiweyo, ukucola + ukuhlelwa + inkqubo yokudada, inkqubo yokugaya inqanaba + inkqubo yokwahlulwa kweqonga, ukuqhotsa + ukwetyisa + inkqubo yokwahlulahlula.
I-oyile-amanzi adityanisiweyo okupholisa umsesane othe nkqo kwisahluli sobuhle obuphezulu sodidi oluphezulu
Ukwenziwa kweeNdibaniselwano zePhosphate zezichumiso zePhosphate
Ukwenziwa kwezichumiso zePhosphate kukuguqula iiminerali zephosphate zibe yiphosphates ezifunxwa lula zizityalo ngenkqubo yokuzuza, ubushushu obuphezulu, kunye nokudibanisa.I-Ammonium phosphate sisichumiso esine-high-efficiency compound eyenziwe nge-asidi ye-phosphoric kumanzi ammonia.Iphosphorus emthubi ifunyanwa ngokufudumeza ilitye lephosphate elixutywe nesanti yequartz kunye necoke kwi-1500°C kwiziko lombane.Kukho iindlela ezimbini zokuvelisa i-asidi ye-phosphoric: indlela ye-sulfuric acid extraction kunye ne-peroxy combustion absorption method.
Umzekelo wokuxhamla
I-fineness of iron tailings e-Hebei yi-200 mesh, ibalwa kwi-63.29%, umxholo we-iron TFe uphelele ngu-6.95%, kunye nomxholo we-P2O5 ngu-6.89%.Intsimbi ikakhulu i-iron oxide efana ne-limonite, i-iron silicate kunye ne-magnetite ngendlela yokufakwa okuqhubekayo;amaminerali aqukethe i-phosphorus ikakhulu i-apatite, i-ganggue minerals i-quartz, i-feldspar, i-calcite, njl. Idibaniswe ngokusondeleyo kunye neeminerali ze-phosphorus.Injongo yovavanyo kukukhetha iiminerali ezahlukeneyo ezinentsimbi ngokuhlukana kwamagnetic, kwaye i-apatite ityetyiswe kwimisila yokwahlukana kwamagnetic.
Ngokutsho kweempawu zeesampulu, inkqubo yokuxhamla inqunywe ngolu hlobo lulandelayo: i-ore eluhlaza ekhethiweyo - i-200 mesh ene-fineness ye-63.29%, yenziwe i-slurry ene-concentration ye-30%, kwaye i-iron magnetic eqhubekayo ikhethiwe. nge-CTB4000GS intsimi yamagnetic ebuthathaka, kwaye i-tailings ikhethwa yindandatho ethe nkqo i-0.5T ebuthathaka i-Magnetic iron oxide kunye ne-iron silicate minerals.
Inkqubo yokuhamba kovavanyo lokususa intsimbi yokwahlula ngokwemagnethi yeentsalela zentsimbi ezinephosphorus
I-iron-containing iron phosphorus tailings iye yafumana inkqubo yokususa isinyithi enye i-roughing kunye neyokutshayela kabini, kwaye iimveliso ze-iron concentrate azikwazanga ukukhethwa kwizinto eziphathekayo.Isiqulatho se-phosphorus kwi-coarse concentrate yonyuswe ukusuka kwi-6.89% ukuya kwi-10.12%, kwaye izinga lokubuyiswa kwe-phosphorus libe ngama-79.54%.%, izinga lokususa intsimbi lalingama-75.83%.Kuvavanyo lokuthelekisa amandla ahlukeneyo entsimi ye-Lihuan 0.4T, 0.6T kunye ne-0.8T, kwafunyaniswa ukuba amandla aphantsi e-Lihuan 0.4T abangele intsimbi eninzi kwi-phosphorus coarse kwaye ihlanjululwe, kunye namandla aphezulu e-0.8 I-T ibangele ukulahleka kwe-phosphorus kwizinto eziphathekayo zamagnetic.Enkulu.Ukukhethwa kweemeko ezifanelekileyo zokwahlukana kwamagnetic kunenzuzo ekuphuculeni isalathiso se-beneficiation yokusebenza kwe-flotation yelitye eliphantsi le-phosphate.
