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.
