Uranium mahakar yau da kuma a nan gaba

Chemical kashi uranium da aka rarraba shi ko'ina a cikin duniya a yanayi. An sani cewa shi ne a cikin tẽku ruwa (3 ug / l), shi ne ba a cikin lithosphere Layer (1.3 × 1014 m). Its main bangare ne a cikin sedimentary kankara, acidic kasa mai arziki a cikin silicon. Impurities samu a rare-ƙasa ma'adanai, thorium kankara.

A Rasha, da "main" uranium jinsin su ne wadannan: naturstan (kuma sau da yawa ake magana a kai a matsayin uraninite da pitchblende), carnotite. Sun bambanta kawai a cikin asalin. Volcanic naturstan more kowa a cikin duwatsu kafa a Paleozoic zamanin da ya biyo baya lokaci a baya shi. Uraninite sau da yawa samu a cikin kankara na Precambrian lokaci, uranium yan zanga-zanga, inda ya mined uranium, sosai matasa: sun samo asali a cikin sedimentary kasa Cenozoic ko wasu, ko da ƙaramin, lokaci.

Wannan chemic kashi fairly ko'ina rarraba jama'a a cikin ƙasa, haka kuma akwai uranium mahakar a kasashe 25. Ainihin adadin (kusan 30%) an samar a Canada da kuma Australia (22%), Afirka (19%). Bisa kididdigar da, Rasha uranium mahakar samar game da 6% na wannan kashi, mined a duniya.

• Open kaya. Wadannan sun hada da gano albarkatun da karya a yankunan da tabbatar da reserves na uranium da kuma sharadi gwargwado domin cin gaban su.
• A uranium reserves a cikin subsoil. Wannan kimantawa ne da za'ayi a cikin m siffar ba tare da asarar da cewa babu makawa bayyana lokacin da marẽmari an tsara uranium.
• Recoverable reserves. A karkashin su fahimci wani takamaiman adadin wannan kashi, cirewa daga mahakar ko da kuwa ta reserves a cikin subsurface.
• Harufan tabbatar da reserves, wakiltar adadin mined da kuma bincika uranium.

Ya kamata a lura da cewa kimanta na uranium reserves a Rasha aka samar da wasu ka'idoji. Yana daukan la'akari ba kawai jikewa na uranium tama, amma kuma halin kaka da cewa za su jawo wa kansu a lokacin ta samar. Saboda haka dauke da cewa uranium mahakar iya dangantaka da mabanbanta ake iya faɗi albarkatu. Daga gare su, C1, P3 + C1, da dai sauransu

Tarayyar Soviet uranium mahakar ne a yankunan da suke yanzu ɓangare na sauran jihohi.

• A Ukraine, shi aka mined (da aka samar a yau) a Kirovograd, Pobuzhsky yankunan. Aiki uranium mahakar a Vatutinsky, Michurinskom, a rãnar nan, Zheltorechenskom da kuma sauran yankunan. Total a Ukraine aiki 12 filayen yau.
• Uranium mahakar a cikin Tarayyar Soviet kasance a kan ƙasa da Kazakhstan. Yau, shi ne mined akwai a cikin Chu-Sarysu uranium tama lardin, Zhambyl yankin, da kuma sauran yankunan.
• Tajikistan har yanzu aiki uranium mahakar a Tashkent, kuma Leninabad yankuna, amma samarwa ba riba a gare su.
• A mahakar suna located in Uzbekistan Uchkuduk, Kendyktyube, Lyavlyakane da Tohumbete.
• A Rasha ma aka mined uranium a cikin Stavropol yankin (Lermontov), Lovozero tundra, a kan Lake Onega, da Kola Larabawa.

A halin yanzu, kawai tabbatar da reserves wannan sinadari a Rasha ne 615 dubu ton, da kuma kimanta samarwa ne kusa da 830 dubu tons. Duk da haka, wani gagarumin ɓangare na adibas da za a ci gaba, aka located in m yankunan.

15 daga 16 da aka sani a Rasha adibas suna located in Zabaikalye (Chita yankin, Streltsovskoye, Birch, kuma Argunskoye Zherlovoye adibas). Don aiki a nan za su iya kawai Mining Hanyar.

Manyan filin (Elkon) ne a Yakutia.

Prospected reserves na uranium a West Siberian yankin a cikin Vitim, a cikin jihar bakin teku sashi na Okhotsk Sea da kuma Lake Ladoga. Wadannan yankunan bukatar mai yiwuwa ganima.

Uranium da ake amfani ba kawai a cikin nukiliya masana'antu ko soja al'amura. A fannin binciken kasa tare da taimakon ƙayyade da shekaru na kankara. A gilashin masana'antu da aka kara wa gilashi to ba shi da wani rawaya ko kore kyalli tabo, uranium mahadi suna fentin ain.
