Suav tungsten tus nqi tswj kev ruaj ntseg raws li Fanya cov kev txhawj xeeb tseem ceeb rau kev lag luam.Smelting factories tseem tsis tshua muaj kev khiav hauj lwm tus nqi cuam tshuam los ntawm ib puag ncig kev tshuaj xyuas thiab kev txhawb nqa los ntawm kev txiav tawm ntawm cov chaw tsim khoom kom ruaj khov tus nqi.Tam sim no tag nrho cov lag luam tseem nyob ntsiag to hauv kev lag luam.

Hauv kev lag luam tungsten concentrate, cov khoom lag luam xav tau los ntawm cov neeg yuav khoom yog ze rau cov nqi tsim khoom, uas txo cov lag luam mining cov txiaj ntsig tau zoo.Tsis tas li ntawd, kev txheeb xyuas ib puag ncig, nag hnyav thiab kub kub ua rau kev tsim khoom nyuaj.Yog li ntawd, cov neeg muag khoom tsis kam muag cov khoom xav txog cov khoom nruj.Tab sis qhov kev thov tsis muaj zog thiab peev nyiaj tsis txaus kuj tseem ua rau lub khw.

Rau ammonium paratungstate (APT) kev ua lag luam, nws nyuaj rau kev yuav cov khoom siv qis qis thiab kev txiav txim los ntawm cov dej ntws tsis tau nce.Muab qhov ntawd, smelting factories tsis ua haujlwm hauv kev tsim khoom.Nrog rau qhov cuam tshuam ntawm Fanya Tshuag kev txhawj xeeb, feem ntau cov tub luam tau ceev faj txog kev xav.

Tungsten hmoov manufacturers tsis zoo siab txog qhov kev cia siab ntawm kev sib tw muab los ntawm cov neeg muag khoom thiab xav tau tus nqi qis ntawm cov tub luam.Tus nqi ntawm tungsten hmoov tsis hloov nrog qhov chaw ua haujlwm me ntsis txhim kho lub lim tiam dhau los thiab kev lag luam tau xaus rau hauv qhov ntau.Qhov kev thov tsis tu ncua tsis muaj zog tuaj yeem hnyav ntawm tus nqi.
