Dhagaxa fosfate waxaa loola jeedaa ereyga guud ee macdanta fosfate-ka ee loo isticmaali karo dhaqaale ahaan, gaar ahaan dhagaxa apatite iyo fosfate-ka. Fosfate-ka huruudka ah, fosfate-ka fosfate-ka, fosfate-ka iyo fosfate-ka kale waxaa loo isticmaalaa caafimaadka, cuntada, kabriidka, rinjiga, sonkorta, dhoobada, difaaca qaranka iyo goobaha kale ee warshadaha.
Astaamaha Macdanta iyo Qaab-dhismeedka Macdanta
Waxaa jira ilaa 120 nooc oo macdan ah oo fosfooraska ku jira oo loo yaqaan dabeecadda, laakiin maadaama macdanaha warshadaha ee fosfooraska ku jira ay yihiin macdanaha fosfooraska ee ku jira dhagaxa apatite iyo fosfooraska. Apatite [Ca5(PO4)3(OH,F)] waa macdan oo qaybteeda ugu weyn ay tahay fosfooraska kaalshiyamka. Waxay leedahay magacyo kala duwan sababtoo ah curiyayaasha kala duwan ee ay ka kooban tahay, sida fluorine iyo chlorine. Macdanaha fosfooraska ku jira ee caadiga ah waa: Fluorapatite, chloroapatite, hydroxyapatite, carbonapatite, fluorocarbon apatite, carbon hydroxyapatite, iwm. Mawduuca aragtiyeed ee P2O5 waa inta u dhaxaysa 40.91 iyo 42.41%. Anions-ka dheeraadka ah ee F, OH, CO3, iyo O ee dhagaxa fosfooraska ayaa is beddeli kara, waxaana jira qaybo badan oo isomorphic ah, sidaa darteed isku-dhafka kiimikada ee macdanta ayaa si weyn isu beddela.
Halabuurka kiimikada caadiga ah ee apatite
- Qaybaha kiimikada 2. MawduucaMeelaha codsiga iyo shuruudaha tusmadaDhagaxa Phosphate waxaa inta badan loo isticmaalaa sidii walxaha ceeriin ee bacriminta fosfoorikska iyo iskudhisyada fosfoorik ee kala duwan, waxaana si weyn loogu isticmaalaa warshadaha kiimikada, daawada, sunta cayayaanka, warshadaha fudud iyo warshadaha militariga.Tiknoolajiyada HabayntaFaa'iido iyo nadiifin
Dhagaxa fosfate waxaa loo qaybin karaa nooca siliceous, nooca calcareous, iyo nooca silicon (calcium)-calcium (silicon). Macdanta la xiriirta inta badan waa quartz, flint, opal, calcite, feldspar, mica, limestone, dolomite, rare earth., magnetite, ilmenite, limonite, iwm., habka flotation waa habka ugu muhiimsan ee loo isticmaalo apatite.
Habka tiknoolajiyadda ee mabda'a ah waxaa inta badan ka mid ah: habka isku-darka ee kala-soocidda magnetic-ka, shiididda + kala-soocidda + habka sabeynta, shiididda marxaladda + habka kala-soocidda marxaladda, dubista + dheefshiidka + habka kala-soocidda.

Habaynta Isku-dhafka Phosphate ee Bacriminta Phosphate
Soo saarista bacriminta fosfate-ka waa in macdanta fosfate-ka loo beddelo fosfate-yo si fudud dhirtu u nuugto iyada oo loo marayo habka beneficiation, heerkulka sare, iyo isku-darka. Ammonium phosphate waa bacrimin isku-dhafan oo waxtar sare leh oo laga sameeyay fosfate-ka aashitada biyaha ammonia. Fosfate-ka jaallaha ah waxaa lagu helaa iyadoo la kululeynayo dhagaxa fosfate-ka oo lagu qasay ciid quartz ah iyo kookaha 1500°C foorno koronto ku shaqeeya. Waxaa jira laba hab oo wax soo saar oo ah fosfate-ka aashitada: habka soo saarista aashitada sulfuric iyo habka nuugista gubashada peroxy.
Tusaale ahaan faa'iidada
Tayada birta ee Hebei waa -200 mesh, taasoo ka dhigan 63.29%, wadarta guud ee TFe ee birta waa 6.95%, iyo P2O5 oo ah 6.89%. Birtu waxay inta badan tahay oksaydh bir ah sida limonite, iron silicate iyo magnetite oo ah qaab isku-dhafan oo joogto ah; macdanta fosfooraska ku jirta waxay inta badan yihiin apatite, macdanta gangue waa quartz, feldspar, calcite, iwm. Waxaa si dhow ula socda macdanta fosfooraska. Ujeeddada tijaabada ayaa ah in la doorto macdano kala duwan oo bir ah oo sita iyadoo la kala saarayo birlabta, apatite-na waxaa lagu hodan ku yahay dabada kala-soocidda birlabta.
Sida laga soo xigtay sifooyinka shaybaarada, habka beneficiation waxaa lagu go'aamiyaa sida soo socota: macdanta cayriin ee la doortay - 200 mesh oo leh fineness 63.29%, waxaa loo sameeyaa slurry oo leh fiirsasho 30% ah, birta magnetic-ka ee joogtada ahna waxaa doorta CTB4000GS oo daciif ah goobta magnetic-ka, daalkuna waxaa doorta giraanta toosan ee 0.5T oo daciif ah oo bir ah oksaydh bir ah iyo macdanaha silicate birta ah.
Socodka habka tijaabada ka saarista birta ee kala soocida magnetic ee daal-ka birta ka kooban fosfooraska
Dabada birta fosfooraska ee ku jirta birta ayaa maray habka ka saarista birta oo ah hal xoqan iyo hal xoqan laba jeer, alaabada birta ee u qalantana laguma soo xuli karin walxaha birlabta. Waxyaabaha fosfooraska ku jira ee fosfooraska adag ayaa laga kordhiyay 6.89% ilaa 10.12%, heerka soo kabashada fosfooraskana wuxuu ahaa 79.54% %, heerka ka saarista birta wuxuu ahaa 75.83%. Tijaabadii isbarbardhigga ee awoodaha goobta ee kala duwan ee Lihuan 0.4T, 0.6T iyo 0.8T, waxaa la ogaaday in xoogga goobta ee hooseeya ee Lihuan 0.4T uu keenay bir aad u badan oo fosfooraska ah oo qallafsan oo la safeeyey, xoogga goobta sare ee 0.8Tna wuxuu sababay luminta fosfooraska ee walxaha birlabta. Weyn. Xulashada xaaladaha kala soocida birlabta ee ku habboon ayaa faa'iido u leh hagaajinta tusmada faa'iidada ee hawlgalka sabeynta ee dhagaxa fosfooraska hoose.
