Udaka olubomvu yintsalela yenkunkuma yemizi-mveliso engcolisayo eveliswa yi-bauxite kwinkqubo yokuvelisa i-alumina. Ibomvu, imnyama ebomvu okanye ingwevu-njengodaka ngenxa yeziqulatho ezahlukeneyo ze-iron oxide. Inomthamo wamanzi aphezulu kwaye iqulethe izinto ezinobungozi ezifana ne-alkali kunye neentsimbi ezinzima. ibe sisifo esinganyangekiyo esichaphazela indalo esingqongileyo. Amacandelo aphambili odaka olubomvu yi-SiO2, i-Al2O3, i-CaO, i-Fe2O3, njl., kwaye iqulethe isixa esikhulu seekhemikhali ze-alkaline. Ixabiso le-pH linokufikelela ngaphezu kwe-11, ene-alkaline enamandla. Njengoko i-bauxite yelizwe lam eliphezulu iyancipha kwaye iyancipha, isixa sodaka olubomvu olukhutshwe kwimveliso ye-1 toni ye-alumina inokufikelela kwi-1.5-2 yeetoni.
Ngokutsho kwedatha evela kwiNational Bureau of Statistics, imveliso ye-alumina yaseChina ngo-2021 iya kuba yi-77.475 yezigidi zeetoni, ukunyuka konyaka-ngonyaka we-5.0%. Ukuba kubalwa ngokusekelwe ekukhutshweni kweetoni ezi-1.5 zodaka olubomvu ngetoni nganye ye-alumina, ukukhutshwa kodaka olubomvu ngo-2021 kuphela kuya kuba phezulu malunga neetoni ze-100 yezigidi, kunye nesantya sokusetyenziswa kodaka olubomvu kwilizwe lam kuphela i-7% . Ukuqokelelana kodaka olubomvu akuhlali kuphela kwimithombo yomhlaba Ukuba ngaba alulawulwa ngokufanelekileyo, kuya kuzisa nemingcipheko efana nokusilela kwedama kwidama elibomvu, ungcoliseko lomhlaba namanzi, njl. njl. Ngoko ke, kungxamisekile ukwandisa ukusetyenziswa kobomvu. udaka.
Udaka olubomvu luhlala luqulathe iintlobo ngeentlobo zesinyithi ezixabisekileyo, ingakumbi intsimbi, i-aluminiyam, i-titanium, i-vanadium, njl., enokuthi iphinde isetyenziswe njengezixhobo ezinokubakho. Inxalenye enkulu ye-Fe2O3 kwinkqubo ye-Bayer yodaka olubomvu ngokuqhelekileyo ingaphezulu kwe-30%, eyona nxalenye yekhemikhali yodaka olubomvu. Kwiminyaka yakutshanje, iNkampani ye-Huate ibilokhu iqhuba uphando kunye nophando malunga nokuhlukana kodaka olubomvu, kwaye iphuhlise isethi epheleleyo. yetekhnoloji yokwahlula intsimbi ebomvu yodaka kunye nomgubo ocolekileyo. , I-40% ukuya kwi-50% yeeminerali zentsimbi kudaka olubomvu inokubuyiswa ngenkqubo ebuthathaka yamagnetic kunye neyombini eyomeleleyo ye-magnetic beneficiation, kunye nezicelo ezinkulu zoshishino ziye zaqhutyelwa eShandong, eGuangxi, eGuizhou, eYunnan nakweminye imimandla. Iimpawu zilungile. Ukubuyiswa kweentsimbi ezixabisekileyo kudaka olubomvu akukwazi nje ukudala inzuzo yezoqoqosho, kodwa nokugcina izixhobo kunye nokunciphisa uxinzelelo lwendalo.
I-oyile-amanzi adityanisiweyo okupholisa umsesane othe nkqo kwisahluli sothambiso oluphezulu lwemagnethi
"Isicwangciso sokuPhunyezwa sokuKhawulezisa ukuPhakanyiswa kokuSetyenziswa okuBanzi kweMithombo yoShishino" kutshanje sikhutshwe ngamasebe asibhozo aquka iSebe lezoShishino kunye nobuChwepheshe boLwazi kunye neSebe lezeNdalo kunye nokusiNgqongileyo libeke phambili iimfuno ezicacileyo zenqanaba lokusetyenziswa kwenkunkuma eninzi eqinileyo kwimizi-mveliso ngexesha. isithuba “seSicwangciso seMinyaka emiHlanu ye-14”. Nangona kunjalo, kusetyenziso olubanzi lodaka olubomvu, kuphela "Uphuculo olusebenzayo" olufunekayo. Oku kungenxa yokuba i-alkali yemichiza edityaniswe nodaka olubomvu kunzima ukuyisusa kwaye umxholo mkhulu, kwaye iqulethe i-fluorine, i-aluminiyam kunye nezinye izinto ezingcolileyo. Ukusetyenziswa ngokungenabungozi kodaka olubomvu bekusoloko kunzima ukuphumeza, ngoko ke ukusetyenziswa ngokupheleleyo kodaka olubomvu kuseyingxaki yehlabathi lonke. . Biza iiyunithi zophando lwezenzululwazi ezifanelekileyo ukuba ziqhubeke nophando olunzulu ngokudityaniswa nobuchwephesha obukhoyo bokusetyenziswa kodaka olubomvu olubanzi ukuze kwandiswe usetyenziso olubanzi lwemithombo yodaka olubomvu.

Iprojekthi yokwahlula intsimbi ebomvu yodaka e-Shandong - Le projekthi iphatha udaka olubomvu lwe-alumina, isebenzisa i-22 LHGC-2000 i-vertical ring high gradient separators magnetic, eyisombulula ngokufanelekileyo ingxaki yonyango lodaka olubomvu kunye nokusetyenziswa okubanzi.
