Madhaka matsvuku itsvina inosvibisa maindasitiri inogadzirwa nebauxite mukugadzira alumina. Iyo yakatsvuka, yakasviba tsvuku kana grey madhaka-sekuda kweakasiyana iron oxide zviri mukati. Iine mvura yakawanda uye ine zvinhu zvinokuvadza zvakadai sealkali uye heavy metals. kuva chirwere chisingaperi chinokanganisa nharaunda yezvakatipoteredza. Izvo zvikamu zvikuru zvedhaka dzvuku iSiO2, Al2O3, CaO, Fe2O3, nezvimwewo, uye ine huwandu hukuru hwemakemikari ealkaline. Iyo pH kukosha inogona kusvika pamusoro pe11, iyo yakasimba alkaline. Sezvo nyika yangu yepamusoro-grade bauxite inova shoma uye shoma, huwandu hwematope matsvuku anobudiswa kubva mukugadzirwa kwe 1 toni yealumina inogona kusvika 1.5-2 matani.
Zvinoenderana nedata kubva kuNational Bureau of Statistics, kuburitswa kwealumina yeChina muna 2021 kuchave 77.475 miriyoni matani, gore negore kuwedzera kwe5.0%. Kana ikaverengwa zvichibva pakubuda kwe1.5 matani edhaka dzvuku patani yealumina, kubuda kwedhaka dzvuku muna 2021 chete kuchakwira kusvika pamamiriyoni zana ematani, uye huwandu hwekushandiswa kwedhaka dzvuku munyika yangu 7% chete. . Kuunganidzwa kwedhaka dzvuku hakungotore zviwanikwa zvevhu Kana zvikasatarisirwa zvakanaka, zvinounza njodzi dzakaita sekutadza kwedhamu redhaka dzvuku, kusvibiswa kwevhu nemvura, nezvimwewo. Naizvozvo, zvinokurumidza kuwedzera kushandiswa kwedhaka. madhaka.
Madhaka matsvuku anowanzo kuve nemhando dzakasiyana dzesimbi dzakakosha, kunyanya kusanganisira simbi, aluminium, titanium, vanadium, nezvimwewo, inogona kudzokororwa sezviwanikwa. Chikamu chikuru cheFe2O3 muBayer process dhaka dzvuku kazhinji iri pamusoro pe30%, inova chikamu chikuru chemakemikari yedhaka dzvuku.Mumakore achangopfuura, Huate Company yanga ichienderera mberi ichiita tsvakiridzo uye tsvakiridzo yekuparadzaniswa kwedhaka dzvuku, uye yakagadzira seti yakakwana. yetekinoroji yekuparadzaniswa kwesimbi tsvuku yematope uye poda yakanaka. , 40% kusvika 50% yemaminerari esimbi mumatope matsvuku anogona kudzoserwa kuburikidza neasina simba remagineti uye maviri akasimba magineti beneficiation process, uye maindasitiri makuru ekushandisa akaitwa muShandong, Guangxi, Guizhou, Yunnan nedzimwe nzvimbo. Zviratidzo zvakanaka. Kudzoreredzwa kwesimbi dzakakosha mumatope matsvuku hakugone chete kugadzira zvikomborero zvehupfumi, asiwo kuchengetedza zviwanikwa uye kuderedza kudzvinyirira kwezvakatipoteredza.

Iyo "Implementation Plan yeKumhanyisa Kusimudzira Kwekushandiswa Kwakazara Kwemaindasitiri Zviwanikwa" nguva pfupi yadarika yakapihwa nemapazi masere anosanganisira Ministry of Indasitiri neRuzivo Tekinoroji uye Ministry of Ecology and Environment vakaisa pachena zvinodikanwa zvehuwandu hwekushandiswa kwehuwandu hwemarara maindasitiri panguva. nguva ye "14th Five-Year Plan". Nekudaro, pakushandiswa kwakazara kwedhaka dzvuku, chete "Kubudirira kuvandudza" kunodiwa. Izvi zvinodaro nekuti kemikari alkali yakasanganiswa nedhaka dzvuku inonetsa kubvisa uye zviri mukati zvakakura, uye zvakare ine fluorine, aluminium uye kumwe kusvibiswa. Kushandiswa kusina ngozi kwedhaka dzvuku kwagara kwakaoma kuita, saka kushandiswa kuzere kwedhaka dzvuku richiri dambudziko renyika yose. . Shevedzera kune akakodzera mayuniti ekutsvagisa sainzi kuti aenderere mberi nekutsvaga kwakadzama pamwe neiyo iripo dzvuku dzvuku dhaka yakazara yekushandiswa tekinoroji kuwedzera kushandiswa kwakadzama kwezviwanikwa zvedhaka dzvuku.
