Icyondo gitukura ni imyanda ihumanya ikirere ikorwa na bauxite mu gihe cyo gukora alumina. Imeze nk'icyondo gitukura, umutuku wijimye cyangwa imvi bitewe n'ibintu bitandukanye birimo icyuma gitukura. Ifite amazi menshi kandi irimo ibintu byangiza nka alkali n'ibyuma biremereye. Iba indwara idakira igira ingaruka ku bidukikije. Ibice by'ingenzi bigize icyondo gitukura ni SiO2, Al2O3, CaO, Fe2O3, nibindi, kandi irimo ingano nini y'ibinyabutabire bya alkali. Agaciro ka pH gashobora kugera hejuru ya 11, aribyo alkali cyane. Uko bauxite yo mu gihugu cyanjye igenda igabanuka, ingano y'icyondo gitukura gisohoka mu ikorwa rya toni 1 ya alumina ishobora kugera kuri toni 1.5-2.
Dukurikije imibare ituruka mu Kigo cy’Igihugu gishinzwe Ibarurishamibare, umusaruro wa alumina mu Bushinwa mu 2021 uzaba toni miliyoni 77.475, ubwiyongere bw’umwaka ku mwaka bwa 5.0%. Iyo bibazwe hashingiwe ku ibyuka bitukura bya toni 1.5 kuri toni ya alumina, ibyuka bitukura mu 2021 gusa bizaba toni miliyoni 100, kandi igipimo cy’ikoreshwa ry’ibyondo bitukura mu gihugu cyanjye ni 7% gusa. Kwiyongera kw’ibyondo bitukura ntikwinjira gusa mu butaka Iyo bidacunzwe neza, bizanateza ibyago nko kwangirika kw’ikigega cy’ibyondo bitukura, kwandura ubutaka n’amazi, nibindi. Kubwibyo, ni ngombwa ko ibyondo bitukura bikoreshwa cyane.
Ibumba ritukura rikunze kuba ririmo ubwoko butandukanye bw'ibyuma by'agaciro, harimo cyane cyane icyuma, aluminiyumu, titaniyumu, vanadium, nibindi, bishobora kongera gukoreshwa nk'umutungo ushobora gukoreshwa. Igice kinini cya Fe2O3 mu ibumba ritukura rya Bayer muri rusange kiri hejuru ya 30%, ari na cyo gice cy'ingenzi cy'ibumba ritukura. Mu myaka ya vuba aha, Huate Company yakomeje gukora ubushakashatsi n'ubushakashatsi ku gutandukanya ibumba ritukura, kandi yateje imbere ikoranabuhanga ryuzuye ryo gutandukanya ibumba ritukura n'ifu nziza. , 40% kugeza kuri 50% by'amabuye y'agaciro mu ibumba ritukura ashobora kugaruzwa binyuze mu nzira yoroheje ya rukuruzi n'uburyo bubiri bukomeye bwo kongera ingufu za rukuruzi, kandi ibikorwa binini byakoreshejwe mu nganda muri Shandong, Guangxi, Guizhou, Yunnan n'ahandi. Ibipimo ni byiza. Kugarura ibyuma by'agaciro mu ibumba ritukura ntibishobora gusa guteza imbere ubukungu, ahubwo binatuma umutungo urokoka kandi bikagabanya igitutu cy'ibidukikije.

"Gahunda yo gushyira mu bikorwa gahunda yo kwihutisha ikoreshwa ry’umutungo w’inganda" iherutse gusohorwa n’amashami umunani arimo Minisiteri y’Inganda n’Ikoranabuhanga mu Itangazamakuru na Minisiteri y’Ibidukikije n’Ibidukikije yashyize ahagaragara ibisabwa kugira ngo habeho ikoreshwa ry’imyanda ikomeye mu nganda mu gihe cy’"Gahunda ya 14 y’Imyaka Itanu". Ariko, kugira ngo ikoreshwe neza, hakenewe "gutunganya neza". Ibi biterwa nuko alkali y’ibinyabutabire ivanze n’icyondo gitukura bigoye kuyikuraho kandi ibirimo ni byinshi, kandi irimo fluorine, aluminiyumu n’indi myanda. Gukoresha nabi icyondo gitukura byagiye bigorana, bityo ikoreshwa ry’icyondo gitukura riracyari ikibazo ku isi yose. . Turasaba inzego zishinzwe ubushakashatsi bwa siyansi gukomeza ubushakashatsi bwimbitse hamwe n’ikoranabuhanga risanzweho ryo gukoresha icyondo gitukura kugira ngo habeho ikoreshwa ry’icyondo gitukura.
