Tungsten qhov chawfeem ntau yog tsim los ntawm cov txheej txheem hmoov metallurgy. Ntawm no yog cov ntsiab lus dav dav ntawm cov txheej txheem:

1. Hmoov ntau lawm: tungsten hmoov yog tsim los ntawm kev txo cov tungsten oxide siv hydrogen lossis carbon ntawm qhov kub thiab txias. Lub resulting hmoov yog ces tshuaj ntsuam kom tau qhov xav tau particle loj tis.

2. Kev sib xyaw: Sib tov tungsten hmoov nrog lwm cov hmoov hlau (xws li npib tsib xee lossis tooj liab) txhawm rau txhim kho cov khoom ntawm cov khoom thiab pab txhawb cov txheej txheem sintering.

3. Compaction: Cov hmoov sib tov yog nias rau hauv cov duab uas xav tau siv hydraulic xovxwm. Cov txheej txheem siv kev kub siab rau cov hmoov, ua rau nws mus rau hauv lub cev ntsuab nrog rau qhov xav tau geometry.

4. Sintering: Lub cev ntsuab yog ces sintered nyob rau hauv ib tug kub kub rauv nyob rau hauv tej huab cua tswj. Thaum lub sij hawm sintering txheej txheem, cov hmoov particles sib txuas ua ke los ua ib qho tuab thiab muaj zog tungsten.

5. Machining thiab xov: Tom qab sintering, tungsten qhov chaw yuav raug kev siv tshuab ntxiv thiab ua tiav cov txheej txheem kom ua tiav qhov ntev thiab qhov zoo.

Zuag qhia tag nrho, cov txheej txheem hmoov metallurgy tuaj yeem tsim qhov nyuaj, ua haujlwm siab tungsten qhov chaw nrog cov khoom siv zoo heev thiab thermal.

Tungsten feem ntau yog mined siv ntau txoj hauv kev, suav nrog qhib qhov av thiab hauv av mining. Nov yog ib qho piv txwv ntawm cov txheej txheem no:

1. Qhib-qhov mining: Nyob rau hauv txoj kev no, qhib qhov av loj yog khawb rau ntawm qhov chaw kom rho tawm tungsten ore. Cov cuab yeej hnyav xws li excavators thiab cov tsheb thauj khoom yog siv los tshem tawm overburden thiab nkag mus rau lub cev ore. Thaum cov ore raug nthuav tawm, nws raug rho tawm thiab thauj mus rau cov nroj tsuag ua kom zoo dua ntxiv.

2. Underground Mining: Hauv kev mining hauv av, tunnels thiab shafts yog tsim kom nkag mus rau tungsten deposits nyob tob hauv qab ntawm qhov chaw. Cov miners siv cov cuab yeej tshwj xeeb thiab cov txheej txheem los rho cov ore los ntawm cov mines hauv av. Cov ore rho tawm ces thauj mus rau saum npoo rau kev ua.

Ob qho tib si qhib qhov thiab hauv av mining txoj kev tuaj yeem siv los rho tawm tungsten, nrog rau kev xaiv ntawm txoj kev nyob ntawm yam xws li qhov tob ntawm lub cev ore, qhov loj ntawm qhov tso nyiaj.ndecoomic feasibility ntawm kev ua haujlwm. 

Ntshiab tungsten tsis pom nyob rau hauv qhov. Hloov chaw, nws feem ntau ua ke nrog lwm cov zaub mov xws li wolframite thiab scheelite. Cov zaub mov no yog mined thiab cov tungsten tau muab rho tawm los ntawm cov txheej txheem ntawm lub cev thiab tshuaj lom neeg. Cov txheej txheem extraction muaj xws li crushing cov ore, tsom rau tungsten ntxhia, thiab tom qab ntawd ua ntxiv kom tau cov hlau ntshiab tungsten lossis nws cov tebchaw. Thaum muab rho tawm, tungsten tuaj yeem ua tiav thiab ua kom zoo dua los tsim cov khoom siv rau ntau yam kev siv engineering.
