Iron miyalayo, kupanga ake ndi ntchito

Iron miyalayo ndi mchere maphunziro apadera kuphatikizapo chitsulo ndi mankhwala ake. Iron miyalayo imatengedwa mu choncho, ngati uli chinthu ichi ndalama zokwanira kukhala chuma kopindulitsa kuchotsa izo.

Mtundu waukulu wa zitsulo ndi magnetite. Lili 70% nitrous oxide ndi chitsulo. miyala iyi ndi mtundu wakuda kapena otuwa. Maginito zitsulo ndi ncho ku Russia mu Urals lapansi. Umapezeka mwa mapiri maginito, mkulu, Grace ndi Kachkanar. Mu Sweden ndi anthu oyandikana nawo Falun dannemorite ndi Gällivare. Mu US - ndi PA, ndipo mu Norway - Arendal ndi Persberg.

Mu chitsulo ndi makampani zitsulo chitsulo mankhwala miyala anawagawa mitundu itatu:

- olekanitsidwa chitsulo ores (zili otsika chitsulo);

- sinter miyala (ndi zomwe zili pafupifupi yachitsulo);

- pellet (chonyowa kulemera chitsulo munali).

mitundu morphological

madipoziti amenewa amaonedwa wolemera chitsulo miyala, amene ali oposa 57% ya chitsulo kapangidwe kake. Pakuti ores osauka anthu amene osachepera 26% chitsulo. Asayansi chitsulo miyala ogaŵikana mitundu iwiri morphological: liniya ndi ploskopodobny.

Iron miyalayo ndi liniya mtundu miyala thupi mphero anaŵerama ndi mabacteria za vuto lapansi. Mtundu amakhala ndi okhutira makamaka mkulu chitsulo (50 69%), koma sulfure ndi phosphorous mu zoterezi miyala lili pang'ono.

madipoziti Ploskopodobnye zimapezeka pamwamba pa zigawo za quartzite ferruginous, zomwe zikusonyeza weathering kutumphuka.

Iron miyalayo. The ntchito ndi kupanga

Olemera chitsulo miyala wapeza ntchito yopangira nkhumba chitsulo ndi makamaka ndi smelt mu Converter ndi lotseguka-moto ng'anjo kapena mwachindunji ndi kuchira chitsulo. A pang'ono ntchito monga utoto achilengedwe (ocher) ndi weighting dongo muds.

Global m'matangadza kufufuza madipoziti amapanga biliyoni 160. Matani, ndi zachitsulo, muli biliyoni 80 matani.. Iron miyalayo opezeka mu Ukraine, ndi yaikulu masitolo chitsulo changwiro ndi Russia ndi Brazil.

Voliyumu ya kupanga dziko miyala limakula chaka chilichonse. Nthawi zambiri, zitsulo ndi ncho ndi njira lotseguka, akamanena za chimene chili choona kuti zipangizo zonse zofunikira laperekedwa kwa mgodi, ndipo mu malo omwewo kumanga ntchito. ntchito pafupifupi akuya pafupifupi 500 m, ndi m'mimba mwake umadalira pa makhalidwe a m'munda anapeza. Pambuyo pake, mothandizidwa ndi zipangizo zina zapadera Tingafinye chitsulo miyala, kuvala makina, kusinthidwa kwa mayendedwe a katundu wolemera, ndi ku miyala ya ku makampani omwe tikugwira processing.

The sangathe wa njira poyera ndi luso kwanga yekha pa akuya osaya. Ngati chozama kwambiri, m'pofunika kumanga wanga. Poyamba, kupanga thunthu, chokhala akuya ndi makoma bwino zokhalamo. Pa zomenyanazo wa makonde thunthu kuwonjezera otchedwa wofuka. Anapeza mwa iwo miyala kuphulika, kenako zidutswa ake anamulerera pamwamba mothandizidwa ndi zipangizo zina zapadera. Iron miyalayo migodi m'njira izi ndi zothandiza koma kumafuna chiopsezo kwambiri ndi mtengo.

Pali njira ina imene ncho chitsulo miyala. Njirayi imatchedwa SRS kapena osati zitsime zokumba zogwiritsa hayidiroliki. The miyala ndi yotengedwa pansi m'njira: bwino ndi mokhomerera, izo ndi adatchithisira mu chitoliro ndi jetting wamphamvu kwambiri madzi ndege wosweka thanthwe limene kukwezedwa pamwamba. Iron miyalayo njira imeneyi ndi otetezeka, koma, mwatsoka, operewera. Choncho amalowerera kupeza okha 3% miyala, ndi 70% amapangidwa kudzera migodi. Komabe, kupanga njira SRS bwino ndipo pali Mwina mkulu kuti m'tsogolo adzakhala njira yaikulu, kuchotsa mabomba ndi quarries.
