Waa maxay faraqa u dhexeeya bauxite cayriin iyo bauxite karsan?

Dalkaygu waa wax-soo-saar weyn oo dhoofiya agabka refractory, iyada oo wax-soo-saarka walxaha refractory ay ka yihiin 65% wadarta guud ee caalamka. Bauxite waa mid ka mid ah alaabta ceeriin ee ugu muhiimsan ee wax soo saarka walxaha dib-u-celinta. Bauxite ee warshadaha refractory caadi ahaan waxa loola jeedaa macdanta bauxite oo leh maaddooyinka Al2O3 la kariyey ee ≥48% iyo ka kooban Fe2O3 hoose. Sida alaabta ceeriin ee muhiimka ah ee alaabta refractory, bauxite waxay ku jirtaa boos aan la bedeli karin.

Farqiga ugu weyn ee u dhexeeya bauxite cayriin iyo bauxite la kariyey waa noocyo kala duwan oo macdan ah: alaabta ceeriin waa kaolinite iyo diaspore, iyo clinker waa mullite. Bauxite clinker, oo loo yaqaan walxo aluminium sare ah, leben aluminium sare oo kala duwan oo laga sameeyay clinker-ka ayaa ah walxaha ka-hortagga ama ka-hortagga daxalka oo si ballaaran loogu isticmaalo warshadaha birta iyo warshadaha kale, gaar ahaan loo isticmaalo dusha sare ee foornooyinka korantada, foornooyinka qarxinta iyo foornooyinka kulul ee dabka . Saamaynta dib-u-celinta waa mid aad u muhiim ah, waxqabadkeeduna wuu ka fiican yahay lebenka caadiga ah ee dhoobada. Bauxite: macdanta aluminium oksaydh oo leh qaacidada kiimikada Al2O3.H2O, Al2O3.3H2O iyo qadar yar oo FE2O3.SiO2 ah. Inta badan waa jaale ilaa casaan sababtoo ah waxay ka kooban tahay bir oxide, sidaas darteed waxaa sidoo kale loo yaqaan "iron vanadium carrada". Waa alaabta ugu muhiimsan ee aluminium dhalada. Bauxite waxa loo kala qaybiyaa darajada birta, kiimikaad, darajada refractory, darajada shiidada, darajada sibidhka, iwm. sida ku cad isticmaalkeeda.

Waxaa loo isticmaalaa in lagu sameeyo walxaha refractory, nooca bauxite waxaa loo yaqaan alumina fasalka refractory.

Alumina clinker leh saamiga ku habboon ee AL2O3/Fe2O3 iyo AL2O3/SiO2 ayaa loo isticmaalaa in lagu dhalaaliyo alumina ·/Fe2O3 iyo AL2O3/SiO2.

Bauxite clinker waxaa loo habayn karaa isku-darka waxaana loo isticmaali karaa agabka celinaya sida birta iyo foornada. 5. Waxa loo farsamayn karaa budo fiican si loogu isticmaalo shubka, dahaarka refractory iyo warshadaha kale. Waxa kale oo loo isticmaali karaa diyaarinta wakiilka biyaha sifaynta polyaluminum ferric chloride.
