[Ulwazi Lwezimayini] Ukusetshenziswa kwemithombo yodaka olubomvu ngeke kubambezeleke. Sicela ususe isethi ephelele yobuchwepheshe bokuhlukanisa insimbi nodaka olubomvu!

ukusebenza8

Udaka olubomvu luyinsalela yemfucuza yezimboni engcolisayo ekhiqizwa i-bauxite ngesikhathi sokukhiqiza i-alumina. Ibomvu, ibomvu ngokumnyama noma ifana nodaka ngenxa yokuqukethwe okuhlukile kwe-iron oxide. Inamanzi amaningi futhi iqukethe izingxenye eziyingozi njenge-alkali nezinsimbi ezisindayo. sibe yisifo esingamahlalakhona esithinta imvelo. Izingxenye eziyinhloko zodaka olubomvu yi-SiO2, Al2O3, CaO, Fe2O3, njll., futhi iqukethe inani elikhulu lamakhemikhali e-alkaline. Inani le-pH lingafinyelela ngaphezu kwe-11, okuyi-alkaline enamandla. Njengoba i-bauxite yezinga eliphezulu yezwe lami iyancipha, inani lodaka olubomvu olukhishwa ekukhiqizeni ithani elingu-1 le-alumina lingafinyelela amathani angu-1.5-2.

Ngokwemininingwane evela ku-National Bureau of Statistics, ukukhishwa kwe-alumina yaseChina ngo-2021 kuzoba amathani ayizigidi ezingama-77.475, okuwukukhuphuka konyaka ngo-5.0%. Uma kubalwa ngokusekelwe ekukhishweni kwamathani angu-1.5 odaka olubomvu ngethani ngalinye le-alumina, ukukhishwa kodaka olubomvu ngo-2021 kuphela kuzoba ngamathani ayizigidi eziyi-100, futhi izinga eliphelele lokusetshenziswa kodaka olubomvu ezweni lami lingama-7% kuphela. . Ukunqwabelana kodaka olubomvu akugcini nje ngokuthatha izinsiza zomhlaba Uma zingaphathwa ngendlela efanele, kuzoletha nezingozi ezifana nokuhluleka kwamadamu echibini lodaka olubomvu, ukungcoliswa kwenhlabathi namanzi, njll. Ngakho-ke, kuyaphuthuma ukwandisa ukusetshenziswa okubomvu. udaka.

Udaka olubomvu ngokuvamile luqukethe izinhlobonhlobo zezinsimbi ezibalulekile, ikakhulukazi okuhlanganisa insimbi, i-aluminium, i-titanium, i-vanadium, njll., engagaywa kabusha njengemithombo engaba khona. Ingxenye enkulu ye-Fe2O3 ku-Bayer inqubo yodaka olubomvu ngokuvamile ingaphezulu kuka-30%, okuyingxenye yamakhemikhali eyinhloko yodaka olubomvu. yobuchwepheshe bokuhlukaniswa kwensimbi yodaka olubomvu kanye nempushana emihle. , 40% kuya ku-50% wamaminerali ensimbi odakeni olubomvu angatholwa ngenqubo ebuthakathaka kazibuthe kanye nezinqubo ezimbili eziqinile zokuzuza kazibuthe, futhi izicelo ezinkulu zezimboni zenziwe eShandong, Guangxi, Guizhou, Yunnan nakwezinye izifunda. Izinkomba zinhle. Ukubuyiselwa kwezinsimbi ezibalulekile odakeni olubomvu akukwazi nje ukudala izinzuzo zezomnotho, kodwa futhi kusindisa izinsiza futhi kunciphise ukucindezelwa kwemvelo.

Ukupholisa okuyinhlanganisela yamanzi kawoyela iringi ethe mpo mpo isihlukanisi kazibuthe

“Uhlelo Lokuqalisa Lokusebenza Lokusheshisa Ukukhuthazwa Kokusetshenziswa Okuphelele Kwezinsiza Zezimboni” olusanda kukhishwa iminyango eyisishiyagalombili okuhlanganisa noMnyango Wezimboni Nobuchwepheshe Bolwazi kanye noMnyango Wezemvelo Nemvelo uveze izidingo ezicacile zenani eliphelele lokusebenzisa imfucuza eqinile yezimboni phakathi nesikhathi. isikhathi “soHlelo Lweminyaka Emihlanu” lwe-14. Nokho, ukuze kusetshenziswe udaka olubomvu ngokuphelele, kudingeka “Ukuthuthukiswa Okuphumelelayo” kuphela. Lokhu kungenxa yokuthi i-alkali yamakhemikhali ehlanganiswe nodaka olubomvu kunzima ukuyikhipha futhi okuqukethwe kukhulu, futhi iqukethe i-fluorine, i-aluminium nokunye ukungcola. Ukusetshenziswa okungenangozi kodaka olubomvu bekulokhu kunzima ukukwenza, ngakho ukusetshenziswa kodaka olubomvu kuseyinkinga yomhlaba wonke. . Cela amayunithi ocwaningo lwesayensi afanele ukuthi aqhubeke nocwaningo olunzulu ngokuhlanganisa nobuchwepheshe obukhona bokusebenzisa udaka olubomvu ukuze kwandiswe ukusetshenziswa okuphelele kwemithombo yodaka olubomvu.

Iphrojekthi yokuhlukanisa insimbi yodaka ebomvu eShandong - Le phrojekthi iphatha udaka olubomvu lwe-alumina, isebenzisa i-22 LHGC-2000 vertical ring high gradient separators magnetic, exazulula ngempumelelo inkinga yokwelashwa kodaka olubomvu nokusetshenziswa okuphelele.
