Cov tungsten hmoov thiab ferro tungsten tus nqi hauv Suav teb tseem tsis muaj zog hloov pauv vim qhov kev thov nyuaj rau kev txhim kho nyob rau lub caij so. Tab sis kev txhawb nqa los ntawm kev nruj ntawm cov khoom siv raw thiab cov txiaj ntsig ntawm cov khoom lag luam smelting, cov neeg muag khoom sim ua kom muaj kev ruaj ntseg tam sim no txawm tias cov kwj deg yuav tsum tau qis dua cov nqi thiab cov tuam txhab 'siab ntawm tus nqi inversion.

Hauv kev lag luam tungsten concentrate, cov neeg koom nrog muaj kev xav nrog kev tos-thiab-saib tus cwj pwm. Lub khw muag khoom thiab cov qauv xav tau yog qhov nyuaj rau kev tawg. Cov neeg yuav khoom thiab cov muag khoom tseem tsis tshua muaj kev lag luam qab los thiab cov khoom lag luam tshiab tau txwv. Qhov chaw tsim khoom muaj peev xwm ntawm tungsten mines yog tswj los ntawm kev tiv thaiv ib puag ncig, txo cov khoom tsim tawm thiab raws caij nyoog.

Smelters tau xaj tsawg dua vim tias cov neeg yuav khoom siv rov ua dua tsis tau raws li kev xav tau ntawm kev ua lag luam. Tsis tas li ntawd, Fanya cov khoom lag luam ntawm tungsten tsis nyob. Yog li ntawd, tag nrho cov lag luam yog ceev faj thiab cov nqi khoom tsis muaj zog txaus kom rov qab los. Tam sim no cov tub luam yuav khoom tsuas yog raws li qhov xav tau tiag tiag.
