Kodi miyalayo? Iron miyalayo gawo. miyalayo Russia

Kuwonjezera mafuta odziwika ndi gasi, pali zina zofunika mchere. Zikuphatikizapo ores, amene ncho chifukwa zitsulo akakhala ndi nonferrous kudzera yobwezeretsanso. Pamaso pa madipoziti miyala - ndi chuma cha dziko.

Kodi miyalayo?

Aliyense wa sayansi zachilengedwe mayankho ake funso limeneli. Mineralogy Mzimuyo mchere miyala monga akaphatikiza ndi, kuphunzira za chimene chili chofunika kusintha m'zigawo ndondomeko ya anthu mtengo wapatali kwambiri, ndipo umagwirira amaphunzira zikuchokera elemental miyala kuti azindikire za Mkhalidwe ndi kachulukidwe zili zitsulo m'menemo.

Nthaka akulingalira funso ili: "Kodi miyala" mawu a moyenera ntchito zawo mafakitale, chifukwa sayansi ndi kuphunzira kwa kapangidwe ndi njira zikuchitika m'katikati lathuli, zinthu mapangidwe miyala ndi mchere, kufufuza za madipoziti latsopano mchere. Iwo akuyimira m'madera padziko lapansi, kumene chifukwa cha njira miyala anapeza kuchuluka zokwanira ntchito mafakitale formations mchere.

Education ores

Motero, funso kuti: "Kodi miyala" Kodi lidzayankhidwa njira chathunthu. Miyalayo - thanthwe ndi mafakitale zitsulo zili mmenemo. Only mu nkhani iyi lili ndi phindu. zitsulo miyala chiphalaphala inakhazikitsidwa m'zaka yozizira, amene limapangidwa mankhwala yace. Komabe, iwo kuwumitsa, iwo anagawira yaikulu ya kulemera kwake atomiki. The aakulu zakhazikika pansi kwa chiphalaphala ndi allocated mu wosanjikiza osiyana. mchere kupanga miyala, ndi otsala a chiphalaphala Madziwo madzimadzi kufalikira pa achabe. Zochitika ali m'bukuli, congealing kupanga chingwe. Miyala, kugwa mchikakamizo cha mphamvu zachilengedwe, kodi waikamo pansi mayiwe, kupanga chitayiko. Malinga zikuchokera miyala anapanga zitsulo miyala zosiyanasiyana.

zitsulo

Mitundu ya mchere osiyana kwambiri. ndi miyala, mu chitsulo makamaka chiyani? Ngati miyala lili okwanira kuchuluka kwa processing mafakitale zitsulo, iwo akutchedwa chitsulo. Iwo amasiyana chiyambi, mipweya, ndipo zili zosafunika zitsulo ndi zomwe kungakhale koyenera. Childs, izi pansiyi zitsulo sanali akakhala, monga chromium kapena faifi tambala, koma palinso zoipa - sulfure kapena phosphorous.

Mipweya ya chitsulo ores anapereka oxides zosiyanasiyana ndi hydroxides kapena asidi salt carbonic wa chitsulo okusayidi. Pokhala anayamba ores ziri zofiira, zofiirira, ndi magnetite ndipo hematite - amaonedwa olemera kwambiri ndipo muli zitsulo oposa 50%. Ndi osauka ndi anthu amene zochepa zothandiza zikuchokera - 25%.

The zikuchokera zitsulo

Maginito chitsulo miyala ndi chitsulo okusayidi. Lili oposa 70% wangwiro, koma limapezeka madipoziti ndi pyrites sulfure, nthawi zina ndi nthaka blende ndi mabungwe ena. Lodestone imatengedwa zabwino ores ntchito. Hematite mulinso 70% chitsulo. Red chitsulo - chitsulo okusayidi - gwero lina la oyera yopanga zitsulo. A analogs zofiirira ndi 60% ya zili zitsulo napeza ndi zosafunika, zina zoipa. Iwo amadzimadzi chitsulo okusayidi ndi limodzi mwa pafupifupi onse ores chitsulo. Iwo alinso yabwino chomasuka kupanga processing Komabe, zitsulo kuwapeza mtundu wa miyala ya otsika khalidwe.

Malinga ndi chiyambi gawo chitsulo miyala, iwo anawagawa m'magulu atatu lalikulu.

1. Amkati kapena magmatogene. mapangidwe awo chifukwa njira geochemical zikuchitika mu kuya kwa matanthwe a pansi padziko, zochitika magmatic.
2. Exogenous, kapena padziko, madipoziti analengedwa chifukwa cha njira zikuchitika m'dera pamwamba pa matanthwe a pansi padziko, ndiko kuti, pansi pa nyanja, mitsinje ndi nyanja.
3. madipoziti Metamorphogenic inakhazikitsidwa pa akuya chokwanira padziko lapansi mu kuthamanga ndi kutentha yomweyo.

Iron nkhokwe miyala mu dziko

Russia wolemera zosiyanasiyana za m'minda. Padziko lonse lapansi - ndi wa Kursk Maginito Anomaly, kupanga pafupifupi 50% ya nkhokwe dziko. M'dera limeneli, ndi anomaly maginito unkachitika m'zaka XVIII, koma chitukuko cha madipoziti linayamba mu 30s Mu zaka zapitazo. nkhokwe miyala mu dziwe ndi okhutira mkulu wa zitsulo koyera, ali amayezedwa mabilioni a matani ndi kukhala poyera kapena mobisa njira.

Bakchar chitsulo miyala gawo, yomwe ndi imodzi yaikulu kwambiri mu dziko ndipo dziko, anatsegula mu 60s Mu zaka zapitazo. miyalayo nkhokwe m'menemo ndi ndende ya chitsulo koyera ndi 60% ali biliyoni matani 30.

The Krasnoyarsk Gawo wakumunda Abagasskoe - ndi magnetite ores. Iwo anapeza mu 30 ntchentche Mu zaka zapitazo, komabe anayamba kukhala yekha mu zaka pafupifupi. Mu North ndi South mabacteria pa dziwe kukhala migodi otsegula dzenje, ndi enieni kuchuluka kwa nkhokwe ndi matani mamiliyoni 73.

Atsegula 1856, komabe mphamvu Abakan chitsulo miyala gawo. Poyamba chitukuko kunachitidwa ndi njira yotseguka ndi 60 ntchentche za m'ma XX - ndi mobisa pa akuya mamita 400. woyenga zitsulo zili miyala abwera 48%.

faifi tambala miyalayo

ndi miyala ya faifi tambala chiyani? Maminolo formations amene ntchito kupanga malonda a zitsulo uyu, wotchedwa faifi tambala ores. Pali sulfide ndi mkuwa ndi faifi tambala zili zitsulo oyera peresenti anayi ndi silicate faifi tambala ores, omwe ndi ofanana ndi chithunzi kwa 2.9 Nchito%. Yoyamba ya gawo kawirikawiri mtundu wa chiphalaphala, ndi ores silicate zili m'madera a weathering kutumphuka.

Kukula kwa makampani faifi tambala mu Russia chikugwirizana ndi chitukuko cha malo awo mu Middle Urals mu zaka za m'ma XIX. Pafupifupi 85% madipoziti sulphide wambiri dera Norilsk. Madipoziti pa Taimyr Peninsula mu kuchuluka ndipo zosiyanasiyana nkhokwe ya mchere - yaikulu komanso wapadera mu dziko, umene uli 56 tebulo nthawi ya zinthu. Mtundu wa faifi tambala ores Russia si wochepa ndi mayiko ena, komanso mwayi n'chakuti Komanso ali ndi zinthu kawirikawiri.

Pa Kola Peninsula ali pafupi khumi peresenti ya chuma faifi tambala sulphide m'minda mu Middle ndi South Urals anayamba madipoziti silicate.

Miyalayo Russia yodziwika ndi chiwerengero ndi zosiyanasiyana chofunika ntchito mafakitale. Komabe, nthawi yomweyo, ali ovuta zinthu zachilengedwe kupanga, likamaomba kudutsa dziko, ndi mismatch wa Kugawilidwa kwanthaka gwero mu dera ndi osalimba a anthu.
