Dhagaxa Phosphate waxaa loola jeedaa ereyga guud ee macdanta fosfatetada oo loo isticmaali karo dhaqaale ahaan, badiyaa apatite iyo phosphate rock. Fosfooraska jaalaha ah, fosfooraska acid, fosfooraska iyo fosfooraska kale ayaa loo isticmaalaa caafimaadka, cuntada, taraqaha, midabada, sonkorta, dhoobada, difaaca qaranka iyo beeraha kale ee warshadaha.
Guryaha Macdanta iyo Dhismaha Macdanta
Waxaa jira ilaa 120 nooc oo macdanta fosfooraska ku jira oo loo yaqaan dabeecadda, laakiin sida fosfooraska ka kooban macdanta warshadaha ayaa inta badan ah macdanta fosfooraska ee apatite iyo phosphate rock. Apatite [Ca5(PO4)3(OH,F)] waa macdan ay qaybteeda ugu weyni tahay kalsiyum phosphate. Waxay leedahay magacyo kala duwan taas oo ay ugu wacan tahay walxaha kala duwan ee ay ku jirto, sida fluorine iyo koloriin. Macdanta ka kooban fosfooraska caadiga ah waa: Fluorapatite, chloroapatite, hydroxyapatite, carbonapatite, fluorocarbon apatite, carbon hydroxyapatite, iwm. Nuxurka aragtiyeed ee P2O5 waa inta u dhaxaysa 40.91 iyo 42.41%. Anions dheeraad ah F, OH, CO3, iyo O ee dhagaxa fosfooraska ayaa beddeli kara midba midka kale, waxaana jira qaybo badan oo isomorphic ah, sidaas awgeed isku-dhafka kiimikada ee macdanta ayaa si weyn u beddelaya.

- Qaybaha kiimikada 2.ContentMeelaha codsiga iyo shuruudaha tusmadaDhagaxa Phosphate waxaa inta badan loo isticmaalaa sida alaabta ceeriin ee bacriminta fosfooraska fosfooraska iyo xeryahooda fosfooraska ee kala duwan, waxaana si ballaaran loogu isticmaalaa dhinacyada warshadaha kiimikada, daawada, sunta cayayaanka, warshadaha iftiinka iyo warshadaha milatariga.Farsamaynta FarsamadaFaa'iidada iyo nadiifinta
Dhagaxa Phosphate waxa loo qaybin karaa nooc siliceous ah, nooca calcareous, iyo silikoon (calcium) -kaalshiyam (silikoon). Macdanta la xidhiidha inta badan waa quartz, flint, opal, calcite, feldspar, mica, limestone, dolomite, dhul dhif ah. , magnetite, ilmenite, limonite, iwm., Habka sabbeynta ayaa ah habka ugu muhiimsan ee faa'iidada apatite.
Habka farsamada ee mabda'a ah inta badan waxaa ka mid ah: sabbeynta + habka kala soocida magnetka ee isku dhafan, shiidida + kala-soocidda + habka sabbeynta, marxaladda shiidida
Isku darka saliidda biyaha qaboojinta giraanta toosan ee kala soocida birlabeedka sare
Habaynta Isku-dhafka Fosfate ee Bacriminta Fosfatka
Wax soo saarka bacriminta fosfattu waa in loo beddelo macdanta fosfatetada phosphates kuwaas oo si fudud ay u nuugaan dhirta iyada oo loo marayo habka ka faa'iidaysiga, heerkulka sare, iyo isku-dhafka. Fosfooraska ammonium waa bacrimiyeyaasha wax-ku-oolnimada sare leh ee laga sameeyay fosfooraska acid ee biyaha ammonia. Fosfooraska jaalaha ah waxaa lagu helaa kuleylinta dhagaxa fosfateetka ah ee lagu qasay ciid quartz iyo kookaha 1500°C ee foornada koronto. Waxaa jira laba hab oo wax-soo-saarka fosfooraska: Habka soo saarista sulfuric acid iyo habka nuugista gubashada peroxy.
Tusaalaha faa'iidada
Wanaagsanaanta dabada birta ee Hebei waa -200 mesh, oo u dhiganta 63.29%, wadarta guud ee birta Tfe waa 6.95%, iyo waxa ku jira P2O5 waa 6.89%. Birtu inta badan waa birta oxide sida limonite, silicate iron iyo magnetite oo ah qaab ka mid ahaanshaha joogtada ah; Macdanta fosfooraska ku jirta inta badan waa apatite, macdanta gangue waa quartz, feldspar, calcite, iwm. Waxay si aad ah ugu dhowdahay macdanta fosfooraska. Ujeedada imtixaanku waa in la doorto macdanta kala duwan ee birta sida kala soocida magnetic, iyo apatite waxaa lagu kobciyaa dabada kala soocida magnetic.
Marka loo eego sifooyinka shaybaarada, habka ka faa'iidaysiga waxaa lagu go'aamiyaa sida soo socota: macdanta cayriin ee la doortay - 200 mesh oo leh ganaax ah 63.29%, ayaa laga sameeyaa slurry leh 30%, iyo birta magnetic joogto ah ayaa la doortay. by CTB4000GS field magnetic daciif ah, iyo dabada waxaa lagu xushay giraanta toosan 0.5T daciif ah Magnetic iron oxide iyo birta silicate macdanta.
Habka socodka kala-soocidda birta ee birta ka saarista birta ee fosfooraska-ku jira dabada birta
Dabada birta ee fosfooraska ee ay ku jirto birta ayaa lagu sameeyay habka birta looga saarayo mid xaaqid ah iyo mid xaaqaya laba jeer. Maadada fosfooraska ee ku jirta xoogga fosfooraska ayaa laga kordhiyey 6.89% ilaa 10.12%, heerka soo kabashada fosfooraskana wuxuu ahaa 79.54%. %, heerka saarista birta wuxuu ahaa 75.83%. Tijaabada isbarbardhigga ee awoodaha kala duwan ee Lihuan 0.4T, 0.6T iyo 0.8T, waxaa la ogaaday in xoogga goobta hoose ee Lihuan 0.4T ay keentay in birta aad u badan ay ku jirto fosfooraska aan fiicneyn oo la safeeyey, iyo xoogga sare ee goobta 0.8 T waxay sababtay luminta fosfooraska ee alaabta magnetic. Wayn Xulashada xaaladaha kala-soocidda magnetic ee ku habboon waxay faa'iido u leedahay in la hagaajiyo tusmada faa'iidada ee hawlgalka sabbeynta ee dhagaxa fosfatka hoose.
