Qhov nruab nrab ntau ntawm scandium nyob rau hauv lub crust yog 36 ′ 10-4 feem pua, uas yog sib npaug rau cov abundance ntawm beryllium, boron, strontium, tin, germanium, arsenic, selenium thiab tungsten, tab sis nws faib yog heev dispersed, thiab nws. yog ib yam kab mob lithophile uas raug cais tawm Nws paub tias muaj ntau dua 800 yam ntawm cov kab mob scandium bearing minerals, tab sis raws li kev ywj pheej scandium minerals, tsuas muaj ob peb hom scandium yttrium ores, scandium hydrophosphate ores, scandosilicate ores thiab titanium silicic acid tsis tshua muaj kub. ore, thiab qhov chaw ore yog me me, uas tsis tshua muaj nyob rau hauv cov xwm txheej
Tam sim no, cov reserves ntawm scandium nyob rau hauv lub ntiaj teb no yog hais txog 2000kt, ntawm uas 90 ~ 95 feem pua yog muaj nyob rau hauv bauxite, phosphorite thiab ferrotitanium ore, thiab ib feem me me nyob rau hauv uranium, thorium, tungsten thiab tsawg lub ntiaj teb ores [49], feem ntau faib. Nyob rau hauv Russia, Tuam Tshoj, Tajikistan, Tebchaws Meskas, Madagascar, Norway thiab lwm lub tebchaws CIS lub teb chaws tau kawm ntau hom kev cuam tshuam nrog scandium deposits. Nws ntseeg tau tias sedimentary bauxite (Sc) deposits tsis tshua muaj nyob rau hauv huab cua leaching hom muaj feem xyuam rau alkaline ultrabasic pob zeb, tsawg ntiaj teb phosphate pob zeb (Sc) deposits thiab ib co hlau titanium (Sc) deposits yog cov tseem ceeb tshaj deposit hom, thiab lawv yog lub ntsiab. qhov chaw ntawm scandium
Tuam Tshoj kuj yog ib lub teb chaws nplua nuj nyob rau hauv scandium kev pab, nrog loj reserves ntawm scandium hais txog cov zaub mov, xws li bauxite thiab phosphorite deposits, porphyry hom thiab quartz leeg hom tungsten deposits nyob rau hauv South Tuam Tshoj, tsawg ntiaj teb deposits nyob rau hauv South Tuam Tshoj, Bayan Obo tsawg ntiaj teb hlau ore. deposit nyob rau hauv Inner Mongolia, thiab Panzhihua vanadium titanium magnetite deposit nyob rau hauv Sichuan Bauxite (Sc) deposit thiab phosphorite (Sc) deposit yog dominant, ua raws li tungsten (Sc) deposit, vanadium titanium magnetite deposit, rare ntiaj teb (Sc) deposit thiab tsawg ntiaj teb hlau (Sc) deposit Nws kwv yees tias cov reserves ntawm scandium nyob rau hauv bauxite thiab phosphorite ore yog hais txog 290, 000 tons, accounting rau 51 feem pua ntawm tag nrho cov reserves ntawm tag nrho cov hom ore scandium. Cov ntsiab lus feem ntau yog cov ntsiab lus nruab nrab ntawm scandium hauv bauxite ore hauv ntiaj teb (38 raws li Sc2O3 μ G / g) 1 ~ 4 zaug, uas yuav dhau los ua ib qho tseem ceeb ntawm cov nyiaj tso nyiaj scandium thiab lub hauv paus tseem ceeb hauv Suav teb.
