Izingxenye ze-Tungstenngokuvamile akhiqizwa ngenqubo ye-powder metallurgy. Nakhu ukubuka konke okujwayelekile kwenqubo:

1. Ukukhiqizwa kwe-Powder: I-Tungsten powder ikhiqizwa ngokunciphisa i-tungsten oxide usebenzisa i-hydrogen noma i-carbon emazingeni okushisa aphezulu. Impushana ewumphumela bese ihlolwa ukuze kutholwe ukusabalalisa usayizi wezinhlayiyana oyifunayo.

2. Ukuxuba: Hlanganisa impushana ye-tungsten nezinye izimpushana zensimbi (njenge-nickel noma ithusi) ukuze uthuthukise izakhiwo zezinto futhi wenze kube lula inqubo yokucwilisa.

3. Ukuhlangana: Impushana exubile ibe isicindezelwa esimeni oyifunayo kusetshenziswa umshini wokunyathelisa nge-hydraulic. Inqubo isebenzisa ukucindezela okuphezulu ku-powder, iyenze ibe umzimba oluhlaza ngejometri oyifunayo.

4. I-Sintering: Umzimba oluhlaza ube usushiswa esithandweni sokushisa okuphezulu ngaphansi kwezimo zomoya ezilawulwayo. Phakathi nenqubo ye-sintering, izinhlayiya zempushana zihlangana ndawonye ukuze zakhe ingxenye ye-tungsten eqinile neqinile.

5. Ukukhanda nokuqeda: Ngemva kokucwenga, izingxenye ze-tungsten zingase zenze izinqubo ezengeziwe zomshini nokuqeda ukuze kuzuzwe ubukhulu bokugcina kanye nekhwalithi yendawo.

Sekukonke, izinqubo ze-powder metallurgy zingakhiqiza izingxenye ze-tungsten eziyinkimbinkimbi, ezisebenza kahle kakhulu ezinezakhiwo ezinhle kakhulu zemishini nezokushisa.

I-Tungsten ivamise ukumbiwa kusetshenziswa izindlela ezahlukahlukene, okuhlanganisa umgodi ovulekile kanye nezimayini ezingaphansi komhlaba. Nasi isifinyezo salezi zindlela:

1. Ukumbiwa kwemigodi evulekile: Ngale ndlela, imigodi emikhulu evulekile imbiwa phezulu ukuze kukhishwe insimbi ye-tungsten. Imishini enzima efana nezimba kanye namaloli athuthwayo asetshenziselwa ukususa umthwalo osindayo kanye nokufinyelela emzimbeni wensimbi. Uma itshe lensimbi selidaluliwe, liyakhishwa bese liyiswa ezindaweni zokucubungula ukuze kuqhutshekwe nokucwengwa.

2. Imayini engaphansi komhlaba: Ezimayini ezingaphansi komhlaba, kwakhiwa imihubhe namashafu ukuze kufinyelele amadiphozithi e-tungsten ajule ngaphansi komhlaba. Abavukuzi basebenzisa amathuluzi akhethekile nezindlela zokukhipha insimbi ezimayini ezingaphansi komhlaba. I-ore ekhishiwe ibe isithuthelwa phezulu ukuze icutshungulwe.

Zombili izindlela zomgodi ovulekile kanye nezimayini ezingaphansi komhlaba zingasetshenziswa ukuze kukhishwe i-tungsten, ngokukhethwa kwendlela kuye ngezinto ezinjengokujula komzimba we-ore, ubukhulu bediphozithi.ndukuba nokwenzeka kwezomnotho komsebenzi. 

I-tungsten ehlanzekile ayitholakali emvelweni. Kunalokho, kuvame ukuhlanganiswa namanye amaminerali afana ne-wolframite ne-scheelite. Lawa maminerali ambiwa futhi i-tungsten ikhishwa ngochungechunge lwezinqubo zomzimba namakhemikhali. Izindlela zokukhipha zihlanganisa ukuchotshozwa kwe-ore, ukugxilisa amaminerali e-tungsten, bese kuqhubeka ukucubungula ukuze kutholwe insimbi ye-tungsten emsulwa noma izinhlanganisela zayo. Uma isikhishiwe, i-tungsten ingaqhubeka icutshungulwa futhi icwengisiswe ukuze kukhiqizwe izinto zokusetshenziswa okuhlukahlukene kobunjiniyela.
