Uyini umehluko phakathi kwe-bauxite eluhlaza kanye ne-bauxite ephekiwe?

Izwe lami lingumkhiqizi omkhulu kanye nomkhiqizi omkhulu wezinto eziphikisayo, ezinomphumela wezinto eziphikisayo ezibalelwa ku-65% yenani eliphelele lomhlaba. I-Bauxite ingenye yezinto zokusetshenziswa eziyinhloko zokukhiqizwa kwezinto eziphikisayo. I-Bauxite embonini ye-refractory ngokuvamile ibhekisela ku-bauxite ore enokuqukethwe kwe-Al2O3 okubaliwe okungu-≥48% nokuqukethwe okuphansi kwe-Fe2O3. Njengempahla ebalulekile yokusetshenziswa kwe-refractory, i-bauxite ithatha indawo engenakushintshwa.

Umehluko omkhulu phakathi kwe-bauxite eluhlaza kanye ne-bauxite ephekiwe yizinhlobo ezahlukene zamaminerali: impahla eluhlaza i-kaolinite ne-diaspore, futhi i-clinker i-mullite. I-Bauxite clinker, ebizwa ngokuthi yi-alumina ephezulu, izitini ezihlukahlukene ze-alumina eziphakeme ezenziwe nge-clinker yayo ziyizinto eziphikisayo noma eziphikisana nokugqwala ezisetshenziswa kakhulu embonini yensimbi nezinye izimboni, ikakhulukazi ezisetshenziswa phezulu kwezithando zikagesi, iziqhumiso zomlilo kanye neziko ezishisayo. . Umphumela we-refractory ubaluleke kakhulu, futhi ukusebenza kwawo kungcono kunezitini ezijwayelekile zobumba eziphikisayo. I-Bauxite: i-aluminium oxide ore enefomula yamakhemikhali ethi Al2O3.H2O, Al2O3.3H2O kanye nenani elincane le-FE2O3.SiO2. Ivamise ukuphuzi kuya kobomvu ngoba iqukethe i-iron oxide, ngakho-ke ibizwa nangokuthi "inhlabathi ye-iron vanadium". Iwumthombo oyinhloko wokuncibilikisa i-aluminium. I-Bauxite ihlukaniswe ngebanga le-metallurgical, ibanga lamakhemikhali, ibanga le-refractory, ibanga lokugaya, ibanga likasimende, njll ngokusho kokusetshenziswa kwayo.

Isetshenziselwa ukwenza izinto eziphikisayo, lolu hlobo lwe-bauxite lubizwa nge-alumina ye-refractory grade.

I-Alumina clinker enezilinganiso ezifanele ze-AL2O3/Fe2O3 kanye ne-AL2O3/SiO2 isetshenziselwa ukuncibilikisa i-alumina·/Fe2O3 kanye ne-AL2O3/SiO2.

I-bauxite clinker ingacutshungulwa ibe yinhlanganisela futhi isetshenziswe njengezinto eziphikisayo njengensimbi neshaja yesithando somlilo. 5. Ingacutshungulwa ibe yimpuphu ecolekileyo ukuze isetshenziswe ekubunjweni, ekuhlanganisweni kwe-refractory nezinye izimboni. Ingasetshenziselwa futhi ukulungiswa kwe-ejenti yokuhlanza amanzi i-polyaluminium ferric chloride.
