Tungsten sassayawanci ana kera su ta hanyar tsarin ƙarfe na foda. Ga cikakken bayanin tsarin:

1. Foda samar da: Tungsten foda aka samar ta hanyar rage tungsten oxide ta amfani da hydrogen ko carbon a high yanayin zafi. Sakamakon foda ana dubawa don samun rabon girman da ake so.

2. Haɗawa: Mix tungsten foda tare da sauran foda na karfe (kamar nickel ko jan karfe) don inganta abubuwan da ke cikin kayan da kuma sauƙaƙe tsarin sinadarai.

3. Compaction: Sai a danna foda mai gauraya zuwa siffar da ake so ta amfani da latsa ruwa. Tsarin yana amfani da babban matsa lamba ga foda, yana samar da shi a cikin jikin kore tare da lissafin da ake so.

4. Sintering: Ana sanya jikin kore a cikin tanderun zafin jiki a ƙarƙashin yanayin yanayi mai sarrafawa. A lokacin aikin sintering, ɓangarorin foda suna haɗuwa tare don samar da ɓangaren tungsten mai girma da ƙarfi.

5. Machining da gamawa: Bayan sintering, tungsten sassa na iya sha ƙarin machining da kuma kammala matakai don cimma karshe girma da kuma surface ingancin.

Gabaɗaya, tafiyar matakai na ƙarfe na foda na iya haifar da hadaddun, sassan tungsten masu girman gaske tare da kyawawan kaddarorin injiniyoyi da thermal.

Tungsten galibi ana hakowa ne ta hanyar amfani da hanyoyi daban-daban, gami da budadden rami da hakar ma'adinan karkashin kasa. Anan ga bayanin waɗannan hanyoyin:

1. Bude rami: Ta wannan hanya, ana haƙa manyan ramukan buɗaɗɗen ramuka a saman sama don hakar ma'adinan tungsten. Ana amfani da manyan kayan aiki irin su injina da manyan motocin daukar kaya don cire nauyi da shiga jikin takin. Da zarar ma'adinan ya tonu, sai a fitar da shi a kai shi zuwa masana'antar sarrafa ta don ci gaba da tacewa.

2. A karkashin kasa mai gina jiki: A karkashin kasa, tunnels da shaff da aka gina don samun damar tungeten adibas located zurfi a karkashin farfajiya. Masu hakar ma'adinai na amfani da na'urori na musamman da dabaru don hako tama daga ma'adinan karkashin kasa. Sannan ana jigilar takin da aka hako zuwa saman don sarrafa shi.

Dukansu buɗaɗɗen ramin da hanyoyin hakar ma'adinai na karkashin kasa za a iya amfani da su don cire tungsten, tare da zaɓin hanyar da ya dogara da dalilai kamar zurfin jikin tama, girman ajiya a.ndyuwuwar tattalin arziki na aiki. 

Tungsten mai tsabta ba a samuwa a cikin yanayi. Maimakon haka, sau da yawa ana haɗa shi tare da sauran ma'adanai irin su wolframite da scheelite. Wadannan ma'adanai ana hako su kuma ana fitar da tungsten ta hanyar tsarin jiki da sinadarai. Hanyoyin da ake hakowa sun hada da murkushe ma'adinan, maida hankali ga ma'adinan tungsten, sannan a kara sarrafa su don samun tsantsar karfen tungsten ko mahadi. Da zarar an fitar da shi, za a iya ƙara sarrafa tungsten kuma a tace shi don samar da kayan aikin injiniya iri-iri.
