Liab av nkos yog qhov zoo heev cov particle muaj zog alkaline cov khib nyiab tsim tawm hauv cov txheej txheem ntawm kev tsim cov alumina nrog bauxite li cov khoom siv raw. Rau txhua tuj ntawm alumina tsim tawm, txog 0.8 mus rau 1.5 tons ntawm av nkos liab yog tsim. Cov nplai loj tso tawm ntawm cov av liab tsis yog nyob hauv av thiab cov khoom siv khib nyiab, tab sis kuj yooj yim ua rau muaj kev phom sij ib puag ncig thiab kev nyab xeeb.Titanium DioxideKhib ua kua yog cov kua roj hmab cov kua khib nyiab ua kua roj ntsha thaum titanium dioxide yog tsim los ntawm cov sulfuric acid txheej txheem. Rau txhua tuj ntawm Titanium Dioxide tsim, 8 txog 10 ntawm cov khoom khib nyiab nrog lub tswv yim ntawm 20% thiab 50 ntawm acidic dej ntws nrog kev pom ntawm 2% yog tsim tawm. Nws muaj cov khoom muaj nuj nqis loj xws li titanium, txhuas, hlau, scandium, thiab sulfuric acid. Kev tshem tawm ncaj qha tsis tsuas yog cov kev coj tsis zoo ib puag ncig, tab sis kuj tseem ua rau cov khoom lag luam poob zoo.
Liab av nkos yog cov khoom siv muaj zog alkaline, thiab cov kua titanium dioxide cov kua yog cov kua acidic. Tom qab nruab nrab ntawm cov kua qaub thiab alkali ntawm ob, cov ntsiab lus tseem ceeb tau ua kom tau cov nqi ntau dua, tab sis kuj tsis tuaj yeem ua kom tau cov khoom siv ntau lawm, thiab muaj peev xwm ua kom tau ntau yam ntxiv rau cov txheej txheem rov qab. Cov kev ua dua tshiab rov sau dua tshiab thiab rov siv dua ntawm ob txoj kev siv nyiaj txiag muaj qee qhov tseem ceeb, thiab covScandium oxidemuaj tus nqi siab thiab txiaj ntsig zoo nyiaj txiag.
Qhov scandium oxide extraction project los ntawm cov av nkos liab thiab titanium dioxide cov kua thiab kev phom sij kev nyab xeeb los ntawm cov av nkos muag thiab titanium dioxide pov tseg. Nws tseem yog qhov tseem ceeb ntawm kev coj cov tswvyim kev txhim kho txuj ci kev tsim kho, txhim kho kev lag luam kev lag luam, thiab ua phooj ywg ib puag ncig, thiab muaj cov txiaj ntsig zoo.
