Udaka olubomvu yintsalela yenkunkuma yemizi-mveliso engcolisayo eveliswa yi-bauxite ngexesha lokuvelisa i-alumina. Ibomvu, ibomvu okanye ingwevu njengodaka ngenxa yokwahluka komxholo we-iron oxide. Inomxholo ophezulu wamanzi kwaye ineenxalenye eziyingozi ezifana ne-alkali kunye neentsimbi ezinzima. Iba sisifo esingapheliyo esichaphazela indalo. Iinxalenye eziphambili zodaka olubomvu yi-SiO2, i-Al2O3, i-CaO, i-Fe2O3, njl., kwaye iqulethe inani elikhulu leekhemikhali ze-alkali. Ixabiso le-pH linokufikelela ngaphezulu kwe-11, eliyi-alkali kakhulu. Njengoko i-bauxite ephezulu yelizwe lam isiya incipha, ubungakanani bodaka olubomvu olukhutshwa kwimveliso yetoni e-1 ye-alumina bunokufikelela kwiitoni eziyi-1.5-2.
Ngokwedatha evela kwi-National Bureau of Statistics, imveliso ye-alumina yaseTshayina ngo-2021 iya kuba yi-77.475 yezigidi zeetoni, ukwanda konyaka nonyaka kwe-5.0%. Ukuba kubalwa ngokusekelwe ekukhutshweni kwe-1.5 yeetoni zodaka olubomvu ngetoni nganye ye-alumina, ukukhutshwa kodaka olubomvu ngo-2021 kuphela kuya kuba phezulu malunga ne-100 yezigidi zeetoni, kwaye izinga lokusetyenziswa ngokupheleleyo kodaka olubomvu kwilizwe lam yi-7% kuphela. Ukuqokelelwa kodaka olubomvu akugcini nje ngokuthatha izixhobo zomhlaba. Ukuba alulawulwa kakuhle, luya kuzisa nemingcipheko efana nokusilela kwedama ledama lodaka olubomvu, ungcoliseko lomhlaba namanzi, njl. Ke ngoko, kungxamisekile ukusetyenziswa kodaka olubomvu kakhulu.
Udaka olubomvu ludla ngokuba neendidi ngeendidi zeesinyithi ezixabisekileyo, kuquka isinyithi, i-aluminium, i-titanium, i-vanadium, njl.njl., ezinokuphinda zisetyenziswe njengezixhobo ezinokubakho. Inxalenye yobunzima be-Fe2O3 kwinkqubo yeBayer udaka olubomvu ngokubanzi ingaphezulu kwe-30%, eliyeyona nxalenye iphambili yekhemikhali yodaka olubomvu. Kwiminyaka yakutshanje, iHuate Company ibisoloko iqhuba uphando nophando malunga nokwahlulwa kodaka olubomvu, kwaye iphuhlise iseti epheleleyo yetekhnoloji yokwahlulwa kwesinyithi sodaka olubomvu kunye nomgubo ocolekileyo. , 40% ukuya kwi-50% yeeminerali zesinyithi kudaka olubomvu zinokufunyanwa ngenkqubo yokunceda amandla emagnethi abuthathaka kunye neembini ezinamandla, kwaye izicelo ezinkulu zemizi-mveliso ziye zenziwa eShandong, eGuangxi, eGuizhou, eYunnan nakwezinye iindawo. Izalathisi zilungile. Ukubuyiselwa kweesinyithi ezixabisekileyo kudaka olubomvu akunakudala kuphela iingenelo zoqoqosho, kodwa nakonga izixhobo kwaye kunciphise uxinzelelo lokusingqongileyo.
Indandatho epholisiweyo edibeneyo yamanzi e-oyile kunye ne-vertical gradient separator ephezulu yemagnethi
"Isicwangciso sokuSebenza sokuKhawulezisa ukuKhuthazwa kokusetyenziswa ngokupheleleyo kwezixhobo zoShishino" esandula ukukhutshwa ngamasebe asibhozo kuquka uMphathiswa wezoShishino noLwazi kunye noMphathiswa we-Ecology kunye neNdalo siveze iimfuno ezicacileyo zesantya sokusetyenziswa ngokupheleleyo kwenkunkuma eqinileyo yemizi-mveliso ngexesha le-"14th Five-Year Plan". Nangona kunjalo, ukuze kusetyenziswe ngokupheleleyo udaka olubomvu, kufuneka kuphela "uphuculo olusebenzayo". Oku kungenxa yokuba i-alkali yekhemikhali edityaniswe nodaka olubomvu kunzima ukuyisusa kwaye umxholo mkhulu, kwaye ikwaqulathe i-fluorine, i-aluminium kunye nezinye izinto ezingcolileyo. Ukusetyenziswa okungenabungozi kodaka olubomvu bekusoloko kunzima ukukwenza, ngoko ke ukusetyenziswa ngokupheleleyo kodaka olubomvu kuseyingxaki yehlabathi. . Biza iiyunithi zophando lwesayensi ezifanelekileyo ukuba ziqhubeke nophando olunzulu kunye netekhnoloji ekhoyo yokusebenzisa ngokubanzi udaka olubomvu ukuze kusetyenziswe ngokupheleleyo izixhobo zodaka olubomvu.
