Nyob rau theem no, tungsten yog ib qho khoom siv tsis tuaj yeem hloov tau thiab cov peev txheej zoo rau kev lag luam hauv lub tebchaws thiab kev tiv thaiv lub tebchaws niaj hnub. Cov cemented carbide ua los ntawm tungsten los ntawm Baoji Yusheng tuam txhab muaj ultra-siab hardness thiab zoo heev hnav tsis kam.
Nws yog siv nyob rau hauv kev tsim ntawm ntau yam cuab yeej txiav cutters, drilling cuab yeej, thiab hnav-resistant qhov chaw. Molybdenum nyob rau hauv tungsten thiab molybdenum yog tsuas yog siv nyob rau hauv hlau thiab steel kev lag luam, feem ntau yog siv ncaj qha rau steelmaking los yog cam khwb cia hlau tom qab raug briquetted los ntawm industrial alumina, thiab ib feem me me yog smelted rau hauv txhuas thiab hlau thiab ces siv rau steelmaking.

Raws li cov ntaub ntawv, tag nrho cov pov thawj reserves ntawm tungsten nyob rau hauv lub ntiaj teb no tsuas yog 2.9 lab tons, faib nyob rau hauv Tuam Tshoj, Canada, Russia, thiab lub tebchaws United States, thiab cov plaub lub teb chaws muaj txog li 84 feem pua; Tuam Tshoj cov peev txheej tungsten muaj ntau. Kev suav txog li 60 feem pua ntawm lub ntiaj teb cov pov thawj pov thawj ntawm tungsten ntxhia cov peev txheej, qeb thib ib hauv ntiaj teb. Tuam Tshoj cov khoom siv tungsten ore yog nplua nuj heev thiab muaj ntau hom kev tso nyiaj, tab sis kev lag luam yog chaotic, cov khoom zoo yog tsawg, thiab homogeneity yog loj. Txawm hais tias tom qab xyoo ntawm kev txiav txim mining rectification, Tuam Tshoj txoj kev lag luam tungsten mining tseem muaj teeb meem loj dhau kev siv. Txij Lub Ib Hlis Ntuj txog Lub Kaum Ib Hlis 2011 Lub Peb Hlis, Tuam Tshoj cov khoom siv tungsten concentrate tau mus txog 120,000 tons, ib xyoos ib zaug nce ntawm 14.06 feem pua. Lub ntiaj teb molybdenum ore reserves yog kwv yees li 8.6 lab tons, thiab thoob ntiaj teb kev faib tawm ntawm molybdenum cov peev txheej yog qhov tsis sib npaug, feem ntau hauv Suav teb, Tebchaws Meskas, thiab Chile, nrog rau ntau tshaj 1.1 lab tons. Hauv xyoo 2010, tag nrho lub ntiaj teb molybdenum ntau lawm yog 214,{18}} tons ntawm molybdenum, ib xyoos ib zaug nce ntawm 12.8 feem pua.
Nrog rau txoj kev loj hlob sai ntawm kev lag luam downstream ntawm tungsten thiab molybdenum refining, qhov kev thov rau tungsten thiab molybdenum refining khoom tsim los ntawm peb lub tuam txhab yuav nce ntxiv (xws lihigh-purity molybdenum hlau), thiab kev loj hlob zeem muag ntawm kev lag luam yog qhov zoo heev.
