Uranium ezimayini namuhla futhi esikhathini esizayo

Chemical isici uranium zisakazwa imvelo eMhlabeni. It is ukuthi emanzini olwandle (3 UG / l) eyaziwa, kuyisici esihlupha ungqimba lithosphere (1.3 × 1014 m). ingxenye yayo oyinhloko kwamadwala sedimentary, nenhlabathi azibukhali ocebile silicon. Ukungcola ezitholakala ezingavamile-umhlaba amaminerali, cindezela amatshe.

ERussia, i- "main" izinhlobo zezinto eziphilayo-uranium yilezi ezilandelayo: naturstan (futhi uvame ukubizwa ngokuthi uraninite futhi pitchblende), carnotite. Ziyahlukahluka kuye kuphela imvelaphi yabo. naturstan Volcanic landile amatshe kwakheka kwenkathi Paleozoic nezikhathi okwalandela ngemva kwaso. Uraninite ngokuvamile etholakala emadwaleni kwesikhathi Precambrian, i-uranium waleli viyo, lapho misela uranium, abasebancane kakhulu: eqale nenhlabathi sedimentary Cenozoic noma ezinye, ngimncane, nezikhathi.

Lo msuka chemic sasivumela ngokulinganayo basakaza kulo lonke Earth, ngakho kukhona ezimayini uranium emazweni angu-25. Inani eliyisisekelo (cishe 30%) ukuthi likhiqizwa eCanada nase-Australia (22%), i-Afrika (19%). Ngokwezibalo, Russia uranium ezimayini ukuphakela mayelana 6% walesi sakhi, misela emhlabeni wonke.

idiphozi ngamunye uranium balinganisela letitsite.

• Vula yokusungula. Zihlanganisa ukuphawula indlela nezisetshenziswa amanga ezindaweni izinqolobane bokuthi uranium nemibandela evumayo zokuthuthukiswa yayo.
• Ezigcina uranium asendaweni. Lokhu kokuhlaziywa wenziwa ifomu okumsulwa ngaphandle ukulahlekelwa ukuthi nakanjani kuphakama lapho iziphethu zenzelwe uranium.
• izinqolobane ukuyithola. Ngaphansi baqonde nemali ethile kwalesi sakhi, ekhishwe ezimayini kungakhathaliseki izinqolobane zayo ku subsurface.
• izinqolobane kokuqala kungase kutholakale, emelela inani uranium misela ukulihlola.

Kufanele kuqashelwe ukuthi isilinganiso uranium izinqolobane eRussia kuveza nezinye izimiso. Ucabangela hhayi kuphela saturation uranium-ore, kodwa futhi izindleko ukuthi kuyodingeka ukuba bazilethele ngesikhathi ukukhiqizwa yayo. Ngakho kubhekwe ukuthi izimayini uranium bangayiqonda izinsiza ezahlukene ngokuphelele nkomoni. Phakathi kwabo, C1, P3 + C1, njll

EU.SSR uranium ezimayini zisezindaweni ukuthi manje eziyingxenye nezinye izifundazwe.

• E-Ukraine, it sasithathwa (futhi kukhiqizwa namuhla) ngo Kirovograd, Pobuzhsky izindawo. Operating ezimayini uranium e Vatutinsky, Michurinskom, Usuku, Zheltorechenskom kanye nezinye izindawo. Ubude e-Ukraine usebenza emikhakheni 12 namuhla.
• ezimayini Uranium e baseSoviet Union ensimini ka Kazakhstan. Namuhla, it is misela lapho Chu-Sarysu uranium-ore sifundazwe, Zhambyl esifundeni, futhi kwezinye izindawo.
• Tajikistan namanje ezisebenza ezimayini uranium e Tashkent futhi Leninabad izifunda, kodwa ukukhiqizwa akuyona inzuzo kubo.
• Ezimayini asezindaweni Uzbekistan Uchkuduk, Kendyktyube, Lyavlyakane futhi Tohumbete.
• ERussia futhi sasithathwa uranium ku laseStavropol esifundeni (Lermontov), Lovozero emathafeni, ku Lake Onega, eNhlonhlweni Yase-Kola.

Okwamanje, kuphela kodwa zibe sebuthweni lezokuvikela bokuthi lesi sici chemical eRussia amathani ayinkulungwane 615, futhi lo mbukiso esivezwa iseduze amathani ayinkulungwane 830. Nokho, ingxenye enkulu imali ukuba athuthukiswe, itholakala ezindaweni ezikude.

15 aphume 16 eyaziwa ngokuba zifakwe Russian asezindaweni Zabaikalye (Chita esifundeni, Streltsovskoye, Birch, futhi Argunskoye Zherlovoye ezifakwa). Ukuze usebenze lapha kungaba kuphela yezimayini indlela.

emkhakheni omkhulu (Elkon) kuyinto e Yakutia.

Ngizihlwayele izinqolobane of uranium eNtshonalanga esifundeni laseSiberia ku Vitim, ogwini lolwandle yoLwandle Okhotsk neLake Ladoga. Lezi zindawo ezidinga inyamazane yawo.

Uranium isetshenziswa hhayi kuphela umkhakha wenuzi noma ezindabeni zezempi. Ngo nokwakheka ngosizo yayo anqume yobudala yamadwala. Imboni ingilazi sengezwe ingilazi ukuze uyinike ophuzi noma oluhlaza Fluorescent ibala, i-uranium compounds zipendwe zobumba.
