Nsimbi, ukukhiqizwa yayo kanye nokusetshenziswa

Nsimbi kuyinto imfundo amaminerali ekhethekile kuhlanganise yensimbi kanye compounds yayo. Nsimbi kubhekwa endabeni yakhe, inkulumo uma iqukethe lesi sici ku okwanele ukuba inzuzo kwezomnotho ukuze kukhishwe khona.

Uhlobo eyinhloko netshe yensimbi magnetite. Iqukethe mayelana 70% i-nitrous oxide ne-ayoni. Lokhu i-ore omnyama noma lwensimbi grey umbala. Magnetic nsimbi limbiwa Russia esifundeni esise-Ural. Litholakala ngaphakathi ezintabeni kazibuthe, ukuphakama, uGrace Kachkanar. ESweden kuwukuthi endaweni Falun dannemorite futhi Gällivare. E-US - a PA, futhi eNorway - Arendal futhi Persberg.

Ngo-ayina steel umkhakha yensimbi imikhiqizo ore zihlukaniswe izinhlobo ezintathu:

- ehlukanisiweko yensimbi imikhando (ongaphakeme yensimbi okuqukethwe);

- Sinter itshe elinensimbi (nge okuqukethwe isilinganiso yensimbi);

- pellet (isisindo ezimanzi yensimbi-aqukethe).

izinhlobo morphological

ezifakwa okunjalo ezibhekwa ocebile nsimbi, aqukethe engaphezu kuka-57% we-iron e ngezithako zawo. Ukuze imikhando abampofu yilezo lapho hhayi ngaphansi kuka-26% yensimbi. Ososayensi nsimbi ihlukaniswe izinhlobo ezimbili morphological: komugqa futhi ploskopodobny.

Nsimbi kuyinto komugqa uhlobo ore umzimba nhlonhlo amajika zokuzamazama yomhlaba iphutha. Lolu hlobo libhekene okusezingeni eliphezulu ikakhulukazi yensimbi okuqukethwe (50 kuya ku 69%), kodwa sulphur ne phosphorus i-ore enjalo iqukethe esincane.

Ploskopodobnye ezifakwa atholakala phezu kwezihloko zamatshe quartzite ferruginous, okuyizinto evamile weathering uqweqwe.

Nsimbi. Ukusetshenziswa futhi kukhiqizwe

Abacebile nsimbi uthola isicelo ngokukhiqiza ingulube yensimbi kanye ikakhulu ukuba aphele kule Converter futhi evulekile-Iziko amaziko noma ngokuqondile yokutakula yensimbi. Inani elincane lisetshenziswa njengendlela udayi yemvelo (ocher) kanye nezilinganiso ubumba muds.

amasheya Global uhlole ezifakwa ezakha bhiliyoni 160. Amathani nensimbi ziqukethe engaba yizigidi eziyizinkulungwane ezingu-80. Amathani. Nsimbi itholakala e-Ukraine, futhi ngobukhulu okumsulwa yensimbi ezitolo une Russia nase Brazil.

Umqulu zomkhiqizo womhlaba ore ikhula njalo ngonyaka. Ezimweni eziningi, le nsimbi yensimbi limbiwa by indlela ivulekile, ngokuyisisekelo elisemandleni yokuthi yonke imishini ezidingekayo silethwa ungowami, endaweni efanayo yokwakha ama-career. umsebenzi isilinganiso mayelana 500 m ukujula, futhi ubukhulu bayo incike izici ezitholakala ensimini. Ngemva kwalokho, ngosizo imishini ekhethekile akhiphe itshe-nsimbi, wabeka emshinini, aguqulelwe ukuthuthwa imithwalo esindayo, ukuletha kusukela inkwali ukuze amabhizinisi okuyinto bekwi ukucubungula.

Ububi indlela evulekile yikhono kwesami ngalesi ukujula engajulile. Uma kuwukuthi ijule ngokungaphezulu, kubalulekile ukwakha okwami. Ekuqaleni, ukwenza isiqu, kepha efaniswe kahle obukhulu nge izindonga kahle enezivikelo eziqinile. Ngezinye izinhlangothi eziphikisanayo imihubhe isiqu ukunweba emigodini okuthiwa. Found kuzo kuqhuma nsimbi, bese izingcezu wakhe baba ebusweni ngosizo imishini ekhethekile. Iron yezimayini ore ngale ndlela iphumelela kodwa kuhilela ingozi engathi sína futhi izindleko.

Kukhona enye futhi indlela lapho misela nsimbi. Ibizwa ngokuthi SRS noma Borehole wokubacindezela. I-ore akhishwa phansi ngendlela yokuthi: emthonjeni is yamba, it is ngihlaliswa ipayipi futhi jetting enamandla kakhulu amanzi jet idwala ochotshoziwe, okuyinto ephakamisa kwamanzi. Nsimbi ngale ndlela iphephile, kodwa, ngeshwa, nesigqi. Ngakho-ke uphatha ukuthola 3% kuphela netshe, futhi u-70% ikhiqizwa nge imiphini. Nokho, ukuthuthukiswa indlela SRS yathuthuka, futhi kukhona awokuthi esikhathini esizayo lizokwakhiwa inketho main, esikhundleni ezimayini nasezinkwalini.
