Madhaka matsvuku itsvina inosvibisa marara emaindasitiri inogadzirwa nebauxite pakugadzira alumina. Itsvuku, tsvuku yakasviba kana grey yakaita sematope nekuda kwemhando dzakasiyana dzesimbi oxide. Ine huwandu hwakawanda hwemvura uye ine zvinhu zvinokuvadza zvakaita sealkali nesimbi dzinorema. Inova chirwere chisingaperi chinokanganisa nharaunda. Zvikamu zvikuru zvedhaka matsvuku ndiSiO2, Al2O3, CaO, Fe2O3, nezvimwewo, uye ine huwandu hwakawanda hwemakemikari ealkaline. pH inogona kusvika pamusoro pe11, iyo ine alkaline zvakanyanya. Sezvo bauxite yepamusoro yenyika yangu ichiderera, huwandu hwedhaka matsvuku hunoburitswa kubva mukugadzirwa kwetani imwe yealumina hunogona kusvika matani 1.5-2.
Sekureva kwedata kubva kuNational Bureau of Statistics, huwandu hwealumina muChina muna 2021 huchava matani mamiriyoni 77.475, kuwedzera kwegore negore kwe5.0%. Kana zvikaverengerwa zvichibva pakuburitswa kwe1.5 matani edhaka dzvuku patani yealumina, kubuda kwedhaka dzvuku muna 2021 chete kuchasvika matani mamiriyoni zana, uye huwandu hwekushandiswa kwedhaka dzvuku munyika yangu hunongova 7%. Kuunganidzwa kwedhaka dzvuku hakungogari chete muvhu Kana rikasatarisirwa zvakanaka, richaunzawo njodzi dzakadai sekutadza kushanda kwedhamu redhaka dzvuku, kusvibiswa kwevhu nemvura, nezvimwewo. Saka, zvakakosha kuti dhaka dzvuku rishandiswe zvakanyanya.
Madhaka matsvuku anowanzo kuve nesimbi dzakasiyana-siyana dzinokosha, dzinosanganisira simbi, aruminiyamu, titanium, vanadium, nezvimwewo, zvinogona kudzokororwa sezvinhu zvinogona kushandiswazve. Chikamu chikuru cheFe2O3 muBayer process madhaka matsvuku chinowanzova pamusoro pe30%, inova ndiyo chikamu chikuru chemakemikari mudhaka matsvuku. Mumakore achangopfuura, Huate Company yave ichienderera mberi nekutsvaga nekutsvagisa pakupatsanurwa kwedhaka matsvuku, uye yakagadzira tekinoroji yakakwana yekupatsanurwa kwedhaka matsvuku iron nehupfu hwakatsetseka. , 40% kusvika 50% yezvicherwa zvesimbi mudhaka matsvuku zvinogona kuwanikwa kuburikidza nemaitiro asina simba emagineti uye maviri akasimba ekuwedzera simba remagineti, uye mashandisirwo makuru emaindasitiri akaitwa muShandong, Guangxi, Guizhou, Yunnan nedzimwe nzvimbo. Zviratidzo zvakanaka. Kudzoserwa kwesimbi dzinokosha mudhaka matsvuku hakungogone kuumba mabhenefiti ehupfumi chete, asiwo kuchengetedza zviwanikwa uye kuderedza kumanikidzwa kwezvakatipoteredza.

"Purogiramu yeKuita Kuti Kukurumidziswe Kukurudzirwa kweKushandiswa Kwakazara kweZviwanikwa zveMaindasitiri" yakaburitswa nguva pfupi yadarika nemadhipatimendi masere anosanganisira Ministry of Industry and Information Technology neMinistry of Ecology and Environment yakajekesa zvinodiwa kuti marara emumaindasitiri ashandiswe zvakanyanya munguva ye "Purogiramu yemakore mashanu yechi14". Zvisinei, kuti pashandiswe matope matsvuku zvakakwana, "Kuvandudza kunobudirira" chete ndiko kunodiwa. Izvi zvinodaro nekuti alkali yemakemikari inosanganiswa nematope matsvuku yakaoma kubvisa uye zvirimo zvakakura, uye inewo fluorine, aruminiyamu nezvimwe tsvina. Kushandiswa kwematope matsvuku kusina njodzi kwagara kuri kwakaoma kuita, saka kushandiswa kwematope matsvuku zvakanyanya kuchiri dambudziko repasi rose. . Kumbirai mayuniti ekutsvagisa kwesainzi akakodzera kuti arambe achitsvagisa zvakadzama pamwe chete netekinoroji iripo yekushandisa matope matsvuku zvakanyanya kuti awedzere kushandiswa kwezviwanikwa zvematope matsvuku zvakanyanya.
