I-Bauxite ngokwenene ibhekisela kwigama eliqhelekileyo le-ores elinokusetyenziswa kwishishini, kunye ne-gibbsite, i-boehmite okanye i-diaspore njengezona zimbiwa eziphambili.Iinkalo zayo zesicelo zinemiba emibini yesinyithi kunye ne-non-metal.I-Bauxite yeyona nto ingcono kakhulu ekrwada kwimveliso yentsimbi ye-aluminium, kwaye ikwayeyona ndawo ibalulekileyo yesicelo.Ukusetyenziswa kwayo kubalela ngaphezulu kwe-90% yemveliso yebauxite yehlabathi iyonke.

Yintoni i-bauxite?

I-Bauxite yiminerali yodongwe esetyenziswa njengeyona nto iphambili kwimveliso ye-aluminiyam.Yenziwa njengemveliso eshiyekileyo kwizigidi zeminyaka ngokwemichiza yemozulu yamatye aqulethe i-aluminiyam silicates.Yaqala ukufunyanwa eFransi ngo-1821, kwaye sele ifunyenwe kwiindawo ezininzi kwihlabathi jikelele.I-Ruiqifeng yakhe ubudlelwane obuqinileyo kunye neSebe le-Guangxi le-CHALCO, elingumvelisi omkhulu wase-China we-alumina, i-aluminiyam yokuqala kunye neemveliso ezicutshungulweyo ze-aluminium.

Isetyenziswa phi iBauxite?

Ukusetyenziswa kwe-non-metallic ye-bauxite ubukhulu becala njengemathiriyeli ye-refractory, i-abrasive materials, iikhemikhali kunye ne-alumina ephezulu yesamente.Nangona umlinganiselo we-bauxite osetyenziswa kwimiba engeyiyo eyentsimbi umncinci, unoluhlu olubanzi losetyenziso.Umzekelo: ngokweemveliso zeekhemikhali, i-sulfate, i-trihydrate kunye ne-aluminium chloride ingasetyenziselwa ukwenza iphepha, ukucocwa kwamanzi, i-ceramics kunye ne-petroleum refining;I-alumina esebenzayo ingasetyenziselwa njenge-catalyst, i-catalyst carrier kunye ne-catalyst kwimichiza, ukucocwa kwe-oyile kunye namashishini amayeza.I-Decolorization, i-dehydration, i-degassing, i-deacidification, ukoma kunye nezinye izibhengezo zomzimba.

I-aluminiyam yentsimbi yeyesibini ngezona zibalulekileyo emhlabeni, emva kwentsimbi.Ngo-1995, ukusetyenziswa kwehlabathi ngomntu ngamnye kwafikelela kwi-3.29kg.Ngenxa yobunzima obuthile obuncinci, umbane olungileyo kunye ne-thermal conductivity, ukwenziwa lula kunye nezinye iipropathi ezigqwesileyo, i-aluminiyam isetyenziswa kakhulu kumacandelo ahlukeneyo oqoqosho lwelizwe.Okwangoku, ukusetyenziswa kwe-aluminiyam enkulu yehlabathi kumacandelo okwakha, ukuthutha kunye nokupakisha, kubalwa ngaphezu kwe-60% yokusetyenziswa kwe-aluminium iyonke.Ialuminiyam sisixhobo sombane esiyimfuneko kwishishini lombane, ishishini lokwenziwa kweenqwelomoya, ishishini loomatshini kunye nezixhobo zoluntu.
