Tungsten, inozivikanwawo sewolfram, ine akawanda maapplication.Inowanzoshandiswa kugadzira magetsiwaya, uye yekudziya uyemagetsi emagetsi.

Iyo yakakosha simbi inoshandiswa zvakare mukatiwelding, heavy metal alloys, masingi ekupisa, mashizha eturbine uye sechinotsiva mutobvu mumabara.

Zvinoenderana neachangoburwa US Geological Survey mushumo pamusoro pesimbi, kugadzirwa kwetungsten yenyika kwakauya pa95,000 MT muna 2017, kubva ku2016's 88,100 MT.

Kuwedzera uku kwakauya kunyangwe kushomeka kwegoho kubva kuMongolia, Rwanda neSpain.Kuwedzera kukuru mukugadzirwa kwakabva kuUK, uko kugadzirwa kwakakwira kunosvika makumi mashanu muzana.

Mutengo we tungsten wakatanga kukwira pakutanga kwe2017, uye wakave nekumhanya kwakanaka kwegore rose, asi tungsten mitengo yakaguma 2018 zvishoma.

Kunyangwe zvakadaro, kukosha kwe tungsten mumaindasitiri ekushandisa, kubva kumafoni kusvika kumabhatiri emota, zvinoreva kuti kudiwa hakuzopera chero nguva munguva pfupi.Uine izvo mupfungwa, zvakakosha kuziva kuti ndedzipi nyika dzinogadzira yakanyanya tungsten.Heino mhedziso yenyika dzakanyanya kugadzira gore rapfuura.

1. China

Kugadzirwa kwemugodhi: 79,000 MT

China yakagadzira tungsten yakawanda muna 2017 kupfuura yayakaita muna 2016, uye yakaramba iri mugadziri mukuru pasi rose nemuganho wakafara.Pakazara, yakaburitsa 79,000 MT ye tungsten gore rapfuura, kubva pa72,000 MT gore rakapfuura.

Zvinogoneka kuti kugadzirwa kweChinese tungsten kungadonha mune ramangwana - nyika yeAsia yakaganhura huwandu hwetungsten-migodhi uye marezinesi ekunze ayo yainopa, uye yakatemera quotas pakugadzira tungsten.Nyika yakawedzerawo kuongororwa kwemhoteredzo munguva pfupi yapfuura.

Pamusoro pekuve mugadziri mukuru wetungsten pasi rose, China ndiyo zvakare inotenga pasi rose mutengi wesimbi.Yakanga iri sosi huru ye tungsten yakaunzwa muUS muna 2017 zvakare, inonzi yaiunza makumi matatu nemana muzana pamutengo wemadhora zana nemakumi mana nemashanu.Mitero yakatemerwa neUS pazvinhu zveChinese sechikamu chehondo yekutengeserana pakati penyika mbiri idzi yakatanga muna 2018 inogona kukanganisa nhamba idzi kuenda kumberi.

2. Vietnam

Kugadzirwa kwemugodhi: 7,200 MT

Kusiyana neChina, Vietnam yakawana kumwe kusvetuka mukugadzirwa kwe tungsten muna 2017. Yakaisa kunze 7,200 MT yesimbi yakaenzaniswa ne6,500 MT gore rapfuura.Masan Resources ane muridzi wepachivande anomhanyisa mugodhi weNui Phao weVietnam, wainoti ndiwo mugodhi mukuru kwazvo unogadzira tungsten kunze kweChina.Iyo zvakare ndeimwe yeanodhura-anodhura anogadzira tungsten munyika.

3. Russia

Kugadzirwa kwemugodhi: 3,100 MT

Kugadzirwa kwetungsten kweRussia kwaive kwakadzika kubva 2016 kusvika 2017, ichiuya pa3,100 MT mumakore ese ari maviri.Bani iri rakauya zvisinei nekuraira kweMutungamiri Vladimir Putin kuti kugadzirwa kutangezve mumunda weTyrnyauz tungsten-molybdenum.Putin anoda kuona yakakura-yakakura migodhi uye yekugadzirisa yakaoma yakamiswa.

Wolfram Kambani ndiyo inogadzira hukuru munyika yezvigadzirwa zve tungsten, maererano newebhusaiti yayo, uye kambani inoti gore rega rega inogadzira anosvika chiuru matani esimbi tungsten poda, pamwe ne6,000 matani e tungsten oxide uye anosvika mazana masere matani e tungsten carbide. .

4. Bolivia

Kugadzirwa kwemugodhi: 1,100 MT

Bolivia yakasungirirwa neUK yekugadzira tungsten muna 2017. Pasinei nemafambiro ekusimudzira indasitiri ye tungsten munyika, kubuda kweBolivia kwakaramba kwakadzika pa1,100 MT.

Indasitiri yezvicherwa yekuBolivia inokanganiswa zvakanyanya neComibol, kambani yehurumende yemugodhi amburera.Iyo kambani yakataura purofiti yemadhora 53.6 miriyoni yegore regore ra2017.

5. United Kingdom

Kugadzirwa kwemugodhi: 1,100 MT

Iyo UK yakaona kusvetuka kukuru mukugadzira tungsten muna 2017, nekubuda kwakakwira kusvika ku1,100 MT zvichienzaniswa ne736 MT gore rakapfuura.Wolf Minerals ingangove yakanyanya kukonzera kuwedzera;mukuwa kwe2015, kambani yakavhura iyo Drakelands (yaimbozivikanwa seHemerdon) tungsten mugodhi muDevon.

Sekureva kweBBC, Drakelands ndiyo yaive yekutanga mugodhi we tungsten kuvhurwa muBritain mumakore anopfuura makumi mana.Nekudaro, yakavhara muna 2018 mushure mekunge Wolf apinda mukutonga.Kambani iyi inonzi haina kukwanisa kuzadzisa zvido zvayo zvenguva pfupi yekushandisa mari.Unogona kuverenga zvakawanda nezve tungsten muUK pano.

6. Austria

Kugadzirwa kwemugodhi: 950 MT

Austria yakagadzira 950 MT ye tungsten muna 2017 zvichienzaniswa ne954 MT gore rapfuura.Zvakawanda zvekugadzirwa ikoko zvinogona kuverengerwa kumugodhi weMittersill, uyo uri muSalzburg uye unobata hombe tungsten dhipoziti muEurope.Mugodhi uyu ndewaSandvik (STO:SAND).

7. Portugal

Kugadzirwa kwemugodhi: 680 MT

Portugal ndeimwe yenyika shoma pane iyi runyorwa iyo yakaona kuwedzera kwekugadzira tungsten muna 2017. Yakaisa kunze 680 MT yesimbi, kubva ku549 MT gore rapfuura.

Mugodhi wePanasqueira ndiwo mugodhi mukuru wePortugal unoburitsa tungsten.Mugodhi weBorralha wakapfuura uchigadzira, waimbova mugodhi wetungsten wechipiri pakukura muPortugal, parizvino ndewaBlackheath Resources (TSXV:BHR).Avrupa Minerals (TSXV: AVU) imwe kambani diki ine tungsten chirongwa muPortugal.Unogona kuverenga zvakawanda nezve tungsten muPortugal pano.

8. Rwanda

Kugadzirwa kwemugodhi: 650 MT

Tungsten ndeimwe yezvicherwa zvakajairika pasi rose, zvichireva kuti zvimwe zvacho zvinogadzirwa munzvimbo dzine mhirizhonga uye zvinotengeswa kuti kurwa kuenderere mberi.Ipo Rwanda yakazvisimudzira sesosi yezvicherwa zvisina mhirizhonga, kunetseka kunoramba kuri pamusoro pekubuda kwe tungsten kubva munyika.Fairphone, kambani inokurudzira "zvemagetsi zvakanaka," iri kutsigira kugadzirwa kwetungsten kuRwanda.

Rwanda yakabudisa 650 MT chete ye tungsten mu 2017, pasi zvishoma kubva 820 MT muna 2016. Dzvanya pano kuti udzidze zvakawanda nezve tungsten muAfrica.

9. Spain

Kugadzirwa kwemugodhi: 570 MT

Kugadzirwa kweTungsten kweSpain kwakadonha muna 2017, kuchipinda pa570 MT.Izvo zviri pasi kubva pa650 MT gore rapfuura.

Kune akati wandei emakambani ari mukutsvaga, kusimudzira uye kuchera tungsten midziyo muSpain.Mienzaniso inosanganisira Almonty Industries (TSXV: AII), Ormonde Mining (LSE: ORM) uye W Resources (LSE:WRES).Unogona kuverenga zvakawanda nezvavo pano.

Zvino zvaunoziva zvakawanda nezve tungsten kugadzirwa uye kwainobva, chii chimwe chaungade kuziva?Tibvunze mibvunzo yako mune zvakataurwa pazasi.
