Bauxite mubyukuri bivuga ijambo rusange ryamabuye y'agaciro ashobora gukoreshwa mu nganda, hamwe na gibbsite, boehmite cyangwa diaspore nk'amabuye y'agaciro.Imirima yacyo ikoreshwa ifite ibintu bibiri byicyuma nicyuma.Bauxite nibikoresho byiza byibanze byo gukora ibyuma bya aluminium, kandi ni ningenzi murwego rwo gukoresha.Imikoreshereze yacyo irenga 90% yumusaruro wa bauxite kwisi yose.

Bauxite ni iki?

Bauxite ni minerval yibumba ikoreshwa nkibikoresho nyamukuru byo gukora aluminium.Yakozwe nkigicuruzwa gisigaye mu myaka miriyoni hamwe nubushakashatsi bwimiterere yibitare birimo silikate ya aluminium.Yavumbuwe bwa mbere mu Bufaransa mu 1821, kuva icyo gihe iboneka ahantu henshi ku isi.Ruiqifeng yagiranye umubano ukomeye n’ishami rya Guangxi rya CHALCO, akaba ari n’Ubushinwa butanga umusaruro mwinshi wa alumina, aluminiyumu n’ibicuruzwa bitunganijwe.

Bauxite ikoreshwa he?

Imikoreshereze idahwitse ya bauxite ni nkibikoresho fatizo byibikoresho bivunika, ibikoresho byangiza, imiti na sima ya alumina.Nubwo igipimo cya bauxite ikoreshwa mubintu bitari ibyuma ni gito, ifite uburyo bwinshi bwo gukoresha.Kurugero: mubijyanye nibicuruzwa bivura imiti, sulfate, trihydrate na aluminium chloride birashobora gukoreshwa mugukora impapuro, gutunganya amazi, kubumba no gutunganya peteroli;alumina ikora irashobora gukoreshwa nka catalizator, itwara catalizator hamwe na catalizator mubikorwa bya shimi, gutunganya amavuta ninganda zimiti.Kurimbisha, kubura umwuma, gutesha agaciro, deacidification, gukama nibindi byamamaza umubiri.

Aluminium yicyuma nicyuma cya kabiri cyingenzi kwisi, nyuma yicyuma.Mu 1995, ku isi umuturage akoresha agera kuri 3.29 kg.Bitewe n'uburemere buke bwihariye, amashanyarazi meza nubushyuhe bwumuriro, gutunganya byoroshye nibindi bintu byinshi byiza, aluminium ikoreshwa cyane mubice bitandukanye byubukungu bwigihugu.Kugeza ubu, aluminiyumu ikoreshwa cyane ku isi iri mu bwubatsi, ubwikorezi no gupakira, bingana na 60% by'ibicuruzwa byose bya aluminium.Aluminium ni ibikoresho by'ingirakamaro mu nganda z'amashanyarazi, inganda zikora indege, inganda z’imashini n'ibikoresho bya gisivili.
