Mwala wa phosphate umatanthauza dzina la mchere wa phosphate womwe ungagwiritsidwe ntchito pazachuma, makamaka apatite ndi phosphate rock. Phosphorus yachikasu, phosphoric acid, phosphide ndi ma phosphate ena amagwiritsidwa ntchito mu zamankhwala, chakudya, machesi, utoto, shuga, ziwiya zadothi, chitetezo cha dziko ndi mafakitale ena.
Katundu wa Mamineral ndi Kapangidwe kake
Pali mitundu pafupifupi 120 ya mchere wokhala ndi phosphorous yomwe imadziwika m'chilengedwe, koma monga mchere wokhala ndi phosphorous, makamaka mchere wa phosphate mu apatite ndi phosphate rock. Apatite [Ca5(PO4)3(OH,F)] ndi mchere womwe gawo lake lalikulu ndi calcium phosphate. Ili ndi mayina osiyanasiyana chifukwa cha zinthu zosiyanasiyana zomwe ili nazo, monga fluorine ndi chlorine. Michere yodziwika bwino yokhala ndi phosphorous ndi iyi: Fluorapatite, chloroapatite, hydroxyapatite, carbonapatite, fluorocarbon apatite, carbon hydroxyapatite, ndi zina zotero. Kuchuluka kwa P2O5 kuli pakati pa 40.91 ndi 42.41%. Anions owonjezera F, OH, CO3, ndi O mu phosphate rock amatha kusinthana, ndipo pali zinthu zambiri za isomorphic, kotero kapangidwe ka mankhwala ka mchere kamasintha kwambiri.
Mankhwala odziwika bwino a apatite
- Zigawo za mankhwala 2. Zomwe zili mkatiMadera ogwiritsira ntchito ndi zofunikira pa indexMwala wa phosphate umagwiritsidwa ntchito makamaka ngati feteleza wa phosphoric acid ndi mankhwala osiyanasiyana a phosphorous, ndipo umagwiritsidwa ntchito kwambiri m'mafakitale a mankhwala, mankhwala, mankhwala ophera tizilombo, mafakitale opepuka komanso mafakitale ankhondo.Ukadaulo WokonzaKupindula ndi kuyeretsa
Mwala wa phosphate ukhoza kugawidwa m'mitundu iwiri: mtundu wa siliceous, mtundu wa calcareous, ndi mtundu wa silicon (calcium)-calcium (silicon). Michere yogwirizana ndi iyi makamaka quartz, flint, opal, calcite, feldspar, mica, limestone, dolomite, rare earth. , magnetite, ilmenite, limonite, ndi zina zotero. Njira yolumikizirana ndiyo njira yofunika kwambiri yopezera phindu la apatite.
Njira yayikulu yaukadaulo imaphatikizapo makamaka: kuyandama + kulekanitsa kwa maginito, kugaya + kugawa + njira yoyandama, kugaya siteji + njira yolekanitsira siteji, kuwotcha + kugaya + njira yogawa.
Mphete yoziziritsa yozungulira yokhala ndi mafuta ndi madzi ophatikizika
Kukonza Mapangidwe a Phosphate a Manyowa a Phosphate
Kupanga feteleza wa phosphate kumatanthauza kusintha mchere wa phosphate kukhala ma phosphate omwe amatengedwa mosavuta ndi zomera kudzera mu njira yophikira, kutentha kwambiri, ndi kupanga. Ammonium phosphate ndi feteleza wopangidwa bwino kwambiri wopangidwa kuchokera ku phosphoric acid m'madzi a ammonia. Phosphorus yachikasu imapezeka potenthetsa miyala ya phosphate yosakanikirana ndi mchenga wa quartz ndi coke pa 1500°C mu uvuni wamagetsi. Pali njira ziwiri zopangira phosphoric acid: njira yochotsera sulfuric acid ndi njira yoyatsira peroxy.
Chitsanzo cha phindu
Kusalala kwa zitsulo zachitsulo ku Hebei ndi -200 mesh, zomwe ndi 63.29%, kuchuluka kwa chitsulo chonse cha TFe ndi 6.95%, ndipo kuchuluka kwa P2O5 ndi 6.89%. Chitsulo makamaka ndi chitsulo cha oxide monga limonite, chitsulo cha silicate ndi magnetite mu mawonekedwe a continuous inclusions; mchere wokhala ndi phosphorous makamaka ndi apatite, mchere wa gangue ndi quartz, feldspar, calcite, ndi zina zotero. Chimagwirizanitsidwa kwambiri ndi mchere wa phosphorous. Cholinga cha mayesowa ndikusankha mchere wosiyanasiyana wokhala ndi chitsulo pogwiritsa ntchito maginito, ndipo apatite imalemeretsedwa ndi zitsulo za maginito.
Malinga ndi makhalidwe a zitsanzo, njira yophikira imatsimikiziridwa motere: miyala yaiwisi yosankhidwa - 200 mesh yokhala ndi fineness ya 63.29%, imapangidwa kukhala slurry yokhala ndi kuchuluka kwa 30%, ndipo chitsulo champhamvu cha maginito chopitilira chimasankhidwa ndi mphamvu ya maginito yofooka ya CTB4000GS, ndipo tailings imasankhidwa ndi mphete yowongoka ya 0.5T weak Magnetic iron oxide ndi minerals yachitsulo ya silicate.
Kuyenda kwa njira yoyezera kuchotsa chitsulo pogwiritsa ntchito maginito poyezetsa chitsulo chokhala ndi phosphorous
Ma chitsulo okhala ndi phosphorous omwe ali ndi chitsulo adutsa njira yochotsera chitsulo kamodzi kozungulira ndi kamodzi kosefa kawiri, ndipo zinthu zoyenera zachitsulo zomwe zimayikidwa mu chitsulo sizinasankhidwe kuchokera kuzinthu zamaginito. Kuchuluka kwa phosphorous mu phosphorous coarse concentrate kunawonjezeka kuchoka pa 6.89% kufika pa 10.12%, ndipo kuchuluka kwa phosphorous komwe kunapezekanso kunali 79.54%. %, kuchuluka kwa chitsulo komwe kunachotsedwa kunali 75.83%. Mu mayeso oyerekeza mphamvu zosiyanasiyana za Lihuan 0.4T, 0.6T ndi 0.8T, zidapezeka kuti mphamvu yochepa ya Lihuan 0.4T inapangitsa kuti phosphorous ikhale yambiri mu phosphorous coarse ndi yoyengedwa, ndipo mphamvu yayikulu ya 0.8T inapangitsa kuti phosphorous itayike muzinthu zamaginito. Yaikulu. Kusankha mikhalidwe yoyenera yolekanitsa maginito ndikothandiza kukonza index ya ubwino wa ntchito yoyandama ya thanthwe lotsika la phosphate.
