Tungsten thiab molybdenumyog tsim nyob rau hauv ntau lub teb chaws nyob ib ncig ntawm lub ntiaj teb no, nrog rau Tuam Tshoj yog tus thawj coj ntawm ob hlau.
Tungsten, tseem hu ua Wolfram, yog cov hlau tsis tshua muaj thiab muaj txiaj ntsig zoo siv hauv ntau yam kev lag luam, suav nrog hluav taws xob, mining, aerospace, thiab kev siv kho mob. Tuam Tshoj tsim ntau dua 80% ntawm lub ntiaj teb tungsten, nrog rau lwm cov neeg tsim khoom tseem ceeb suav nrog Russia, Canada, Nyab Laj, Bolivia, thiab Tebchaws Meskas.
Molybdenum, lwm yam hlau tseem ceeb, feem ntau yog siv rau hauv kev tsim cov hlau alloys, nrog rau hauv kev lag luam aerospace, tiv thaiv, thiab lub zog kev lag luam. Tuam Tshoj kuj tseem yog cov neeg tsim khoom loj tshaj plaws ntawm molybdenum, ua raws li Tebchaws Meskas, Chile, Peru, thiab Canada.
Zuag qhia tag nrho, qhov kev thov rau tungsten thiab molybdenum tseem muaj zog, nrog rau cov hlau yog cov khoom tseem ceeb hauv ntau cov thev naus laus zis niaj hnub no. Thaum ntau lawm yog nyob rau hauv ob peb lub teb chaws tseem ceeb, lub ntiaj teb no muaj nyob ntawm cov ntaub ntawv no ua kom muaj kev ruaj khov rau kev lag luam thoob ntiaj teb.
