Monga chimodzi mwazitsulo zakale kwambiri komanso zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi, chitsulo ndi chinthu chofunikira kwambiri popanga chitsulo ndi chitsulo.Pakalipano, chuma chachitsulo chikuchepa, chomwe chimadziwika ndi chiwerengero chapamwamba cha ore ore poyerekeza ndi ore olemera, ore ogwirizana kwambiri, ndi zolemba zovuta za ore.Chitsulo nthawi zambiri chimachokera ku miyala yake, yotchedwa hematite kapena magnetite, kudzera mu njira yotchedwa iron ore beneficiation.Njira zenizeni zomwe zimakhudzidwa pakuchotsa chitsulo m'mafakitale zimatha kusiyanasiyana kutengera mtundu wa ore ndi zinthu zomwe mukufuna, koma kachitidwe kake kamakhala ndi magawo otsatirawa:
Migodi
Madipoziti achitsulo amayamba kudziwika kudzera muzofufuza.Ndalama zikapezeka, miyalayo imachotsedwa pansi pogwiritsa ntchito njira zamigodi monga dzenje lotseguka kapena migodi yapansi panthaka.Gawo loyambali ndilofunika kwambiri chifukwa limakhazikitsa njira zotsatsira.
Kuphwanya ndi Kupera
Mwala wochotsedwawo umaphwanyidwa m’zidutswa ting’onoting’ono kuti zitheke kukonzedwanso.Kuphwanya kumachitika pogwiritsa ntchito nsagwada kapena ma cone crushers, ndipo kugaya kumachitika pogwiritsa ntchito mphero zongogawira kapena mphero za mpira.Izi zimachepetsa miyalayi kukhala ufa wabwino, zomwe zimapangitsa kuti zikhale zosavuta kuzigwira ndikuzikonza m'magawo otsatirawa.
Kupatukana kwa Magnetic
Chitsulo nthawi zambiri chimakhala ndi zonyansa kapena mchere wina womwe umayenera kuchotsedwa usanagwiritsidwe ntchito popanga chitsulo ndi chitsulo.Kupatukana kwa maginito ndi njira yodziwika bwino yolekanitsa maginito a maginito ndi omwe si a maginito.Maginito amphamvu, monga olekanitsa maginito a Huate, amagwiritsidwa ntchito kukopa ndikulekanitsa tinthu tating'ono tachitsulo kuchokera ku gangue (zosafunikira).Sitepe iyi ndi yofunika kwambiri kuti miyalayo ikhale yoyera.
Kupindula
Chotsatira ndicho kupindula kwa miyala, komwe cholinga chake ndikuwonjezera chitsulo pogwiritsa ntchito njira zosiyanasiyana.Kuchita zimenezi kungaphatikizepo kuchapa, kuyeza, ndi njira zolekanitsira mphamvu yokoka kuti achotse zonyansa ndi kuwongolera mwala.Kupindula kungaphatikizepo kuyandama, kumene mankhwala amawonjezeredwa ku miyala yachitsulo kuti tinthu tachitsulo tiyandamale ndi kupatukana ndi zina zonse.
Pelletizing kapena Sintering
Pamene ore wakhala beneficiated, pangafunike kuti agglomerate zabwino particles mu zikuluzikulu kuti imayenera processing.Pelletizing imaphatikizapo kupanga timatabwa tating'onoting'ono tozungulira pogwetsa miyalayo ndi zowonjezera monga laimu, bentonite, kapena dolomite.Kutentha, kumbali ina, kumaphatikizapo kutenthetsa chindapusa cha ore limodzi ndi kuphulika ndi mphepo yamkuntho kuti apange misa yosakanikirana yotchedwa sinter.Njirazi zimakonzekeretsa miyalayi kuti ifike pomaliza kutulutsa pokonzanso mawonekedwe ake komanso momwe amagwirira ntchito.
Kusungunula
Gawo lomaliza pakuchotsako ndikusungunula, pomwe chitsulo chimatenthedwa mung'anjo yoyaka moto pamodzi ndi coke (mafuta amafuta a carbon) ndi miyala ya laimu (yomwe imagwira ntchito ngati flux).Kutentha kwakukulu kumaphwanya miyalayo kukhala chitsulo chosungunuka, chomwe chimasonkhanitsa pansi pa ng'anjo, ndi slag, yomwe imayandama pamwamba ndikuchotsedwa.Chitsulo chosungunukacho chimaponyedwa m'mawonekedwe osiyanasiyana, monga ma ingots kapena ma billets, ndikukonzedwanso kuti apeze chitsulo ndi zitsulo zomwe akufuna.
Ndikofunika kuzindikira kuti zitsulo zosiyanasiyana zosungiramo zitsulo ndi mafakitale opangira zinthu zimatha kukhala ndi kusiyana kwa njira zomwe zimagwiritsidwa ntchito, koma mfundo zonse zimakhala zofanana.Kuchotsa chitsulo kuchokera ku ore ndi njira yovuta komanso yambiri yomwe imafuna kuyang'anira mosamala zipangizo ndi teknoloji.Kuphatikizika kwa zipangizo zamakono monga Huate magnet separator kumawonjezera mphamvu ndi khalidwe la kupatukana, kuonetsetsa kuti chomalizacho chimakwaniritsa zofunikira pakupanga zitsulo ndi zitsulo.
