Cov av nkos liab yog cov khoom zoo heev uas muaj zog alkaline cov khoom pov tseg uas tsim nyob rau hauv cov txheej txheem ntawm kev tsim alumina nrog bauxite li raw khoom. Rau txhua tuj ntawm alumina tsim, li ntawm 0.8 mus rau 1.5 tons ntawm av nkos yog tsim. Loj-loj cia cov av nkos liab tsis tsuas yog nyob hauv av thiab pov tseg cov peev txheej, tab sis kuj yooj yim ua rau ib puag ncig muaj kuab lom thiab muaj kev nyab xeeb.Titanium dioxideCov kua khib nyiab yog cov kua dej khib nyiab uas tsim tawm thaum titanium dioxide tsim los ntawm txoj kev sulfuric acid. Rau txhua tuj ntawm titanium dioxide tsim, 8 mus rau 10 tons ntawm khib nyiab acid nrog ib tug concentration ntawm 20% thiab 50 mus rau 80 m3 ntawm acidic khib nyiab nrog ib tug concentration ntawm 2% yog tsim. Nws muaj ntau yam khoom tseem ceeb xws li titanium, txhuas, hlau, scandium, thiab sulfuric acid. Kev tso tawm ncaj qha tsis tsuas yog ua phem rau ib puag ncig, tab sis kuj ua rau kev poob nyiaj txiag loj.
Cov av nkos liab yog cov khib nyiab muaj zog alkaline, thiab titanium dioxide pov tseg kua yog kua qaub. Tom qab neutralizing cov kua qaub thiab alkali ntawm ob, cov ntsiab lus tseem ceeb yog kev rov ua dua tshiab thiab siv, uas tuaj yeem tsis tsuas yog txuag cov nqi tsim khoom, tab sis kuj txhim kho qib ntawm cov khoom muaj txiaj ntsig hauv cov khoom pov tseg lossis cov kua dej pov tseg, thiab muaj txiaj ntsig zoo rau kev rov qab los tom ntej. txheej txheem. Kev rov ua dua tshiab thiab rov siv dua ntawm ob qho kev lag luam pov tseg muaj qee qhov tseem ceeb hauv kev lag luam, thiabscandium oxide hmoovmuaj txiaj ntsig zoo thiab kev lag luam zoo.
Qhov project scandium oxide extraction los ntawm cov av nkos liab thiab titanium dioxide pov tseg cov kua yog qhov tseem ceeb heev los daws cov kev ua qias tuaj ib puag ncig thiab kev nyab xeeb los ntawm cov av nkos liab thiab titanium dioxide pov tseg cov kua paug. Nws tseem yog ib qho tseem ceeb ntawm kev siv lub tswv yim kev txhim kho kev tshawb fawb, hloov pauv txoj kev loj hlob ntawm kev lag luam, txhim kho kev lag luam ncig, thiab tsim kom muaj peev txheej txuag nyiaj thiab ib puag ncig tus phooj ywg, thiab muaj txiaj ntsig zoo hauv zej zog.
