I-Bauxite (i-bauxite ore) ibhekisa kwigama elidityanisiweyo leeminerali ezinokuthi zisetyenziswe kushishino, ikakhulu eyenziwe yi-gibbsite, i-boehmite, okanye i-diaspore. Sisixhobo esingahlaziyekiyo. I-bauxite ecocekileyo imhlophe ngombala kwaye ingabonakala ingwevu, eluhlaza, okanye ebomvu ngokukhanyayo ngenxa yokungcola okwahlukeneyo. I-Bauxite inoluhlu olubanzi lwezicelo zamashishini. Kwelinye icala, yeyona nto iphambili ekuveliseni ialumina, ethi yona ivelise ialuminiyam. Kwelinye icala, isetyenziswa kakhulu njengemathiriyeli ekrwada kumashishini anjengezinto eziphikisayo, i-corundum edibeneyo, izinto zokusila, iimveliso ze-ceramic, iimveliso zekhemikhali, kunye noludaka oluphezulu lwe-alumina.

Calcined bauxite contains hydrated alumina and aluminum hydroxide, obtained by calcining high-quality bauxite at high temperatures (85°C to 1600°C) in a rotary kiln. It is one of the main raw materials for producing aluminum. Compared with the original bauxite, after removing moisture through calcination, the alumina content of the calcined bauxite can be increased from about 57% to 58% of the original bauxite to 84% to 88%.

Iimpawu zeMveliso

88	0-1,1-3,3-5	＞88	<9	<0.2	<3	<2
85	0-1,1-3,3-5	＞85	<7	<0.2	<2.5	<2

Usetyenziso

Ishishini le-aluminiyam: i-bauxite inomxholo ophezulu we-aluminiyam kwaye yinto ebalulekileyo ekrwada kwishishini lokunyibilikisa i-aluminium;
2. Ukuchithwa ngokuchanekileyo: i-bauxite inokwenziwa kwiindidi ezahlukeneyo zokubunjwa kwe-mold emva kokucutshungulwa, ngokukodwa isetyenziswe kunxibelelwano, izixhobo, oomatshini kunye namashishini ezixhobo;
3. Izinto eziphikisayo: I-bauxite ineempawu ezintle ezifana nokwandiswa kwe-thermal ephantsi, i-refractoriness ephezulu, kunye nokuzinza kweqondo lobushushu obuphezulu, okwenza kube yinto eqhelekileyo ekrwada kwizinto eziphikisayo. Izinto ezichasayo ezenziwe ngayo zisetyenziswa ngokubanzi kwintsimbi, i-metallurgy non-ferrous, i-petroleum, iikhemikhali kunye nezinye iindawo zoshishino.
4. Izinto zokwakha: i-bauxite powder inokuphucula amandla kunye nobunzima bezinto ezifana nesamente, i-mortar, kunye nekhonkrithi, ngelixa iphinda ikhulise ukuqina kwayo kunye nokuxhathisa ukubola.
