Zviwanikwa zveAluminium
Vanhu vazhinji vanowanzofunga kuti simbi ndiyo simbi yakawanda kwazvo pasi pano.Kutaura zvazviri, aruminiyamu ndiyo simbi yakawanda kwazvo mugoko repasi, ichiteverwa nesimbi.Aluminium inoita 7.45% yehuremu hwese hwepasi, kanenge kaviri. yakawanda sesimbi!Pasi pazere nearuminiyamu makomboni, sevhuwo zvaro, rine aruminiyamu oxide yakawanda, Al2O3.Ore inonyanya kukosha ndeye bauxite.Kuitika kwebauxite munyika kunogona kukamurwa kuita zvikamu zvitatu: Cenozoic. laterite deposits pamatombo esilicic, ayo anoita 80% yepasi rose zvakachengetwa; Paleozoic karstic deposits inoitika pamusoro pe carbonate rocks account for about 12% of the global total reserves;Paleozoic (kana Mesozoic) Chihewen deposits, inoitika pamusoro penzvimbo, inotora chikamu che2% chezvese zvakachengetwa pasi rose.
Aluminium properties
Aluminium inhengo yesirivha uye inogoneka yekemikari element boron boka.
Aluminium yave inonyanya kushandiswa kwete-ferrous simbi nekuda kwekushomeka kwayo nekuda kwekufamba, kushomeka kwesimba, kuderera kwesimba uye maitiro ayo ekugadzira alloys ane akasiyana makemikari zvinhu zvakaita semhangura, zinc, manganese, silicon uye magnesium, izvo zvine zvakawanda. yakagadziridzwa mechanical properties.Aluminium isimbi yechidiki iyo isipo mune zvakasikwa sechinhu chekutanga, asi muchimiro chemukomboni aluminium oxide (Al2O3).Al2O3 ine nzvimbo yakakwirira yekunyungudika uye haisi nyore kuderedzwa, izvo zvinoita kuti aluminium iwanikwe kunonoka.Muna 1825, Musayendisiti weDanish Ostete akaderedza anhydrous aluminium chloride ne potassium amalgam, mamirigiramu mashomanana ealuminium esimbi.
Muna 1954, musayendisiti wechiFrench De Vere akabudirira kushandisa nzira yekuderedza sodium kuti atore simbi yealuminium, asi simbi yealuminium inogadzirwa nemakemikari nzira inodhura kupfuura goridhe, uye inongoshandiswa pakugadzira helmets, tableware, matoyi nezvimwe zvakakosha zvakashandiswa naNapoleon. mhuri yehumambo.Nekugadzirwa kweHall-Heru smelting process uye Bayer process yekugadzira alumina, aruminiyamu yakatanga kushandiswa zvakanyanya mukupera kwezana ramakore rechi 19. Kusvikira nhasi, nzira mbiri idzi dzichiri huru (zvechokwadi inenge iyo chete) nzira dzekugadzira aluminium uye alumina.
Aluminium Production Process
Aluminium ndeyemukati yakapfuma kwazvo mune yakasikwa element, iyo huru indasitiri ye bauxite ore, bauxite nebayer process senge yekunatsa maitiro ealuminium, alumina ne electrolytic aluminium kunyunguduka se (inozivikanwawo sealuminium), saka iyo indasitiri yealuminium mune yekumusoro indasitiri cheni. inogona kukamurwa kuita migodhi bauxite, alumina kunatsa - matatu links senge aruminiyamu kunyunguduka, kazhinji, Matani mana e bauxite anogona kuburitsa matani maviri ealuminium, ayo anogona kuburitsa tani imwe yekutanga aluminium.
