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, engumvelisi omkhulu waseTshayina 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 okwakhiwa, 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.
