Migodi ureniamu lero ndi m'tsogolo

Chemical mchitidwe ureniamu ndi inafalitsidwa mu chikhalidwe dziko lapansi. Amadziwika kuti ndi madzi nyanja (3 ug / l), alipo mu lithosphere wosanjikiza (1.3 × 1014 m). mbali yake yaikulu ndi m'matanthwe nyanja, dothi acidic wolemera pakachitsulo. Zosafunika opezeka mchere kawirikawiri-lapansi, thorium miyala.

Mu Russia, ndi "chachikulu" ureniamu mitundu izi: naturstan (Nthawi zambiri amatchedwa uraninite ndi pitchblende), carnotite. Akusiyana okha anachokera. naturstan chiphala ambiri mwa miyala anapanga m'nyengo Paleozoic ndi nthawi wotsatira kuseri kwa icho. Uraninite amapezeka miyala ya nthawi Precambrian, ureniamu gululi kumene ncho ureniamu, wamng'ono kwambiri: anachokera ku dothi nyanja Cenozoic kapena ena, ngakhale wamng'ono, nthawi.

Izi amafotokozera chemic mwachilungamo wogawana anagawira padziko lapansi, choncho pali mabomba ureniamu m'mayiko 25. Kuchuluka zofunika (pafupifupi 30%) chifukwa amapangidwa ku Canada ndi Australia (22%), Africa (19%). Malinga ndi kafukufuku, Russia ureniamu migodi kupereka 6% ya mchitidwe uwu, ncho padziko lonse.

Aliyense gawo ureniamu Akuti ndi muyezo yeniyeni.

• Open kulingalira. Zikuphatikizapo akudzizindikiritsa chuma kuti ili m'madera ndi nkhokwe kutsimikiziridwa wa ureniamu ndi zinthu yabwino kwa chitukuko.
• Nkhokwe ureniamu mu subsoil ndi. kuwunika Izi ikuchitika mu mawonekedwe woyera popanda zomvetsa kuti zivute zitani wapatsidwa akasupe tinapangidwa ureniamu.
• Recoverable nkhokwe. Pansi iwo kumvetsa zochepa za chinthu ichi, yotengedwa kuchokera ku migodi kaya nkhokwe zake subsurface lapansi.
• Koyamba nkhokwe kutsimikiziridwa, kuimira kuchuluka kwa ncho ndi kufufuza ureniamu.

Tikumbukenso kuti amayesa nkhokwe ureniamu mu Russia ndi kutulutsa mfundo zina. Iwo amaganizira osati machulukitsidwe wa ureniamu miyala, komanso ndalama zimene adzayenera kupatsidwa pa ulimi wake. Choncho ankaona kuti mabomba ureniamu mukugwirizana chuma chosiyana pang'ono. Pakati pawo, C1, P3 + C1, etc.

USSR ureniamu migodi ali m'madera omwe tsopano ali mbali ya limati zina.

• Mu Ukraine, izo ncho (ndi amapangidwa lero) mu Kirovograd, Pobuzhsky malo. Zikugwira ntchito m'migodi ureniamu mu Vatutinsky, Michurinskom, Day, Zheltorechenskom ndi m'madera ena. Total ku Ukraine ukugwira 12 minda lero.
• migodi ureniamu ku Soviet Union anali pa dera la Kazakhstan. Masiku ano ncho mu Chu-Sarysu m'chigawo ureniamu miyala, Zhambyl dera, ndi m'madera ena.
• Tajikistan ankagwira ntchito m'migodi ureniamu mu Tashkent ndi Leninabad m'madera koma kupanga si lipindulitsa pa iwo.
• migodi The zili Uzbekistan Uchkuduk, Kendyktyube, Lyavlyakane ndi Tohumbete.
• Mu Russia komanso anali ncho ureniamu m'dera Stavropol (Lermontov), Lovozero Titafika pamalo, pa Nyanja Onega, ndi Kola Peninsula.

Pakali pano, koma nkhokwe kutsimikiziridwa elementi mankhwala Russia ndi matani 615 zikwi, ndi kupanga ntchito ndi matani pafupifupi 830 zikwi. Komabe, mbali yaikulu ya madipoziti kuti chikule, ili m'madera akumidzi.

15 mwa 16 amadziwika madipoziti Russian zili Zabaikalye (Chita dera, Streltsovskoye, Birch, ndi madipoziti Argunskoye Zherlovoye). Ntchito pano likhoza migodi njira.

munda waukulu (Elkon) ali Yakutia.

Prospected nkhokwe ya ureniamu mu West Siberia dera mu Vitim, m'dera la m'mphepete mwa nyanja ya Okhotsk Nyanja ndi Nyanja Ladoga. Mbali zimenezi zimafuna oyembekezera nyama.

Ureniamu ntchito osati makampani nyukiliya kapena zochitika asilikali. Mu nthaka ndi thandizo ake kudziwa zaka za miyala. makampani galasi anawonjezera kuti galasi kuti kupereka chikasu kapena wobiriwira fulorosenti banga, ureniamu mankhwala opaka zadothi.
