Matope ofiira ndi zinyalala za mafakitale zomwe zimadetsa mpweya zomwe zimapangidwa ndi bauxite popanga alumina. Ndi matope ofiira, ofiira kapena a imvi chifukwa cha zinthu zosiyanasiyana za iron oxide. Ali ndi madzi ambiri ndipo ali ndi zinthu zoopsa monga alkali ndi zitsulo zolemera. Amakhala matenda osatha omwe amakhudza chilengedwe. Zinthu zazikulu za matope ofiira ndi SiO2, Al2O3, CaO, Fe2O3, ndi zina zotero, ndipo ali ndi mankhwala ambiri a alkali. pH imatha kufika pamwamba pa 11, yomwe ndi ya alkali kwambiri. Pamene bauxite yapamwamba kwambiri m'dziko langa ikuchepa, kuchuluka kwa matope ofiira omwe amatuluka kuchokera ku kupanga tani imodzi ya alumina kumatha kufika matani 1.5-2.
Malinga ndi deta yochokera ku National Bureau of Statistics, kuchuluka kwa alumina ku China mu 2021 kudzakhala matani 77.475 miliyoni, kuwonjezeka kwa chaka ndi chaka kwa 5.0%. Ngati kuwerengedwa kutengera kutulutsa kwa matani 1.5 a matope ofiira pa tani imodzi ya alumina, kutulutsa kwa matope ofiira mu 2021 kokha kudzakhala kokwera kufika matani pafupifupi 100 miliyoni, ndipo kuchuluka kwa matope ofiira omwe amagwiritsidwa ntchito mdziko langa ndi 7% yokha. Kuchuluka kwa matope ofiira sikungokhudza nthaka yokha. Ngati sikusamalidwa bwino, kudzabweretsanso zoopsa monga kulephera kwa madamu a matope ofiira, kuipitsidwa kwa nthaka ndi madzi, ndi zina zotero. Chifukwa chake, ndikofunikira kugwiritsa ntchito matope ofiira mwachangu.
Matope ofiira nthawi zambiri amakhala ndi zitsulo zamtengo wapatali zosiyanasiyana, makamaka chitsulo, aluminiyamu, titaniyamu, vanadium, ndi zina zotero, zomwe zitha kubwezeretsedwanso ngati zinthu zomwe zingatheke. Gawo lalikulu la Fe2O3 mu Bayer process matope ofiira nthawi zambiri limakhala pamwamba pa 30%, chomwe ndi gawo lalikulu la mankhwala a matope ofiira. M'zaka zaposachedwa, Huate Company yakhala ikuchita kafukufuku ndi kafukufuku wopitilira pakulekanitsa matope ofiira, ndipo yapanga ukadaulo wathunthu wolekanitsa chitsulo ndi ufa wabwino. , 40% mpaka 50% ya mchere wachitsulo mu matope ofiira amatha kubwezedwa kudzera mu njira yofooka ya maginito ndi njira ziwiri zamphamvu zopangira maginito, ndipo ntchito zazikulu zamafakitale zachitika ku Shandong, Guangxi, Guizhou, Yunnan ndi madera ena. Zizindikiro ndizabwino. Kubwezeretsa zitsulo zamtengo wapatali mu matope ofiira sikungopanga phindu lazachuma, komanso kusunga chuma ndikuchepetsa kupsinjika kwa chilengedwe.
Mphete yoziziritsa yozungulira yokhala ndi mafuta ndi madzi ophatikizika
"Ndondomeko Yoyendetsera Ntchito Yofulumizitsa Kulimbikitsa Kugwiritsa Ntchito Bwino Zinthu Zamakampani" yomwe yatulutsidwa posachedwapa ndi madipatimenti asanu ndi atatu kuphatikiza Unduna wa Zamalonda ndi Ukadaulo Wazidziwitso ndi Unduna wa Zachilengedwe ndi Zachilengedwe yapereka momveka bwino zofunikira pakugwiritsa ntchito zinyalala zolimba zamafakitale ambiri panthawi ya "Ndondomeko ya Zaka Zisanu ya 14". Komabe, kuti matope ofiira agwiritsidwe ntchito mokwanira, "Kukonza kogwira mtima" kokha ndikofunikira. Izi zili choncho chifukwa mankhwala a alkali ophatikizidwa ndi matope ofiira ndi ovuta kuchotsa ndipo zomwe zili mkati mwake ndi zazikulu, komanso zimakhala ndi fluorine, aluminiyamu ndi zinyalala zina. Kugwiritsa ntchito matope ofiira kopanda vuto kwakhala kovuta nthawi zonse, kotero kugwiritsa ntchito matope ofiira mokwanira ndi vuto padziko lonse lapansi. . Itanani magulu ofufuza asayansi oyenerera kuti apitirize kufufuza mozama pamodzi ndi ukadaulo wogwiritsa ntchito matope ofiira womwe ulipo kuti agwiritse ntchito bwino zinthu za matope ofiira.
