Icyondo gitukura nigisigara cyangiza imyanda yinganda ikorwa na bauxite mugikorwa cyo kubyara alumina. Ni umutuku, umutuku wijimye cyangwa icyatsi kimeze nkibintu bitandukanye bya okiside ya fer. Ifite amazi menshi kandi irimo ibice byangiza nka alkali nicyuma kiremereye. guhinduka indwara idakira yibasira ibidukikije. Ibice byingenzi bigize ibyondo bitukura ni SiO2, Al2O3, CaO, Fe2O3, nibindi, kandi birimo imiti myinshi ya alkaline. Agaciro pH gashobora kugera hejuru ya 11, ni alkaline. Mugihe igihugu cyanjye cya bauxite yo mu rwego rwo hejuru kigenda kigabanuka, ubwinshi bwibyondo bitukura biva mu musaruro wa toni 1 ya alumina birashobora kugera kuri toni 1.5-2.
Dukurikije imibare yaturutse mu kigo cy’igihugu gishinzwe ibarurishamibare, umusaruro wa alumina mu Bushinwa mu 2021 uzaba toni miliyoni 77.475, umwaka ushize wiyongereyeho 5.0%. Niba ubaze hashingiwe ku myuka ya toni 1.5 y’ibyondo bitukura kuri toni ya alumina, imyuka y’ibyondo bitukura mu 2021 yonyine izaba igera kuri toni zigera kuri miliyoni 100, kandi ikoreshwa ry’ibyondo bitukura mu gihugu cyanjye ni 7% gusa. . Ikusanyirizo ry'ibyondo bitukura ntabwo rifite umutungo wubutaka gusa Niba bidacunzwe neza, bizanazana ingaruka nko kunanirwa n’urugomero rw’ikigega gitukura cy’icyondo gitukura, ubutaka n’amazi yanduye, n’ibindi rero, birihutirwa gukoresha cyane umutuku. icyondo.
Icyondo gitukura gikubiyemo ibyuma bitandukanye byagaciro, cyane cyane birimo ibyuma, aluminium, titanium, vanadium, nibindi, bishobora gutunganywa nkibishobora kuba umutungo. Igice kinini cya Fe2O3 mugikorwa cya Bayer icyondo gitukura muri rusange kiri hejuru ya 30%, kikaba aricyo kintu nyamukuru cyimiti yibyondo bitukura.Mu myaka yashize, Isosiyete ya Huate yakomeje gukora ubushakashatsi nubushakashatsi ku gutandukanya ibyondo bitukura, kandi yashyizeho uburyo bwuzuye y'ikoranabuhanga ryo gutandukanya icyuma gitukura n'ifu nziza. , 40% kugeza kuri 50% byamabuye y'agaciro mucyondo gitukura arashobora kugarurwa binyuze mumashanyarazi adakomeye hamwe nuburyo bubiri bukomeye bwo kugirira akamaro, kandi inganda nini nini zakozwe munganda zakozwe muri Shandong, Guangxi, Guizhou, Yunnan no mu tundi turere. Ibipimo ni byiza. Kugarura ibyuma byagaciro mubyondo bitukura ntibishobora guteza inyungu mubukungu gusa, ahubwo binabika umutungo kandi bigabanya umuvuduko wibidukikije.

“Gahunda yo gushyira mu bikorwa gahunda yo kwihutisha iterambere ry’imikoreshereze y’umutungo w’inganda” iherutse gutangwa n’amashami umunani arimo Minisiteri y’inganda n’ikoranabuhanga mu itumanaho ndetse na Minisiteri y’ibidukikije n’ibidukikije yashyize ahagaragara ibisabwa bisobanutse neza ku gipimo cy’imikoreshereze yuzuye y’imyanda myinshi y’inganda mu gihe igihe cya "Gahunda yimyaka 14 yimyaka itanu". Ariko, kugirango ukoreshe byuzuye ibyondo bitukura, gusa "Gukora neza" birakenewe. Ni ukubera ko imiti ya alkali ihujwe nicyondo gitukura biragoye kuyikuramo kandi ibirimo ni binini, kandi irimo na fluor, aluminium nindi myanda. Gukoresha nabi ibyondo bitukura byahoze bigoye kubikora, kubwibyo gukoresha neza ibyondo bitukura biracyari ikibazo kwisi yose. . Hamagara ibice byubushakashatsi byubumenyi kugirango ukomeze ubushakashatsi bwimbitse bufatanije nubuhanga buriho bwo gukoresha ibyondo bitukura kugirango ukoreshe neza umutungo wibyondo bitukura.
