Seimwe yematare ekutanga uye anonyanya kushandiswa pasi rose, iron ore chinhu chakakosha pakugadzirwa kwesimbi nesimbi.Parizvino, zviwanikwa zvesimbi zviri kupera, zvinoratidzwa nechikamu chepamusoro cheore yakaonda kana ichienzaniswa neyakapfuma ore, yakawanda yakabatana ore, uye yakaoma ore nziyo.Simbi inowanzobviswa kubva musimbi yayo, inozivikanwa sehematite kana magnetite, kuburikidza nemaitiro anonzi iron ore beneficiation.Matanho chaiwo anosanganisirwa mukudhirowa kwesimbi muindasitiri anogona kusiyana zvichienderana nerudzi rweore uye zvigadzirwa zvinodikanwa, asi maitiro ese anowanzo sanganisira anotevera matanho:
Mining
Iron ore deposits inotanga kuonekwa kuburikidza nemabasa ekuongorora.Kana dhipoziti yawanikwa, simbi yacho inotorwa kubva pasi pachishandiswa nzira dzekuchera dzakaita segomba rakavhurika kana kuchera pasi pevhu.Iyi nhanho yekutanga yakakosha sezvo ichiisa nhanho yeanotevera ekubvisa maitiro.
Kupwanya uye Kukuya
Ore inobviswa inopwanywa kuita zvidimbu zvidiki kuti zvifambire mberi kugadzirwa.Kupwanya kunowanzoitwa uchishandisa shaya dzinopwanya kana cone crushers, uye kukuya kunoitwa uchishandisa autogenous kugaya mill kana bhora zvigayo.Izvi zvinoderedza ore kuita hupfu hwakatsetseka, zvichiita kuti zvive nyore kubata nekugadzirisa mumatanho anotevera.
Magnetic Separation
Iron ore kazhinji ine tsvina kana zvimwe zvicherwa zvinoda kubviswa isati yashandiswa mukugadzira simbi nesimbi.Magnetic separation inzira yakajairika inoshandiswa kupatsanura magineti zvicherwa kubva kune asiri magineti.Magineti akasimba, akadai seHuate magnet separator, anoshandiswa kukwezva nekuparadzanisa zvidimbu zvesimbi kubva kune gangue (zvisingadiwi).Danho iri rakakosha pakuvandudza kuchena kwesimbi.
Beneficiation
Nhanho inotevera ndeyekubatsirwa kweore, uko chinangwa ndechekuwedzera simbi yemukati kuburikidza nemaitiro akasiyana.Iyi nzira inogona kusanganisira kugeza, kuongorora, uye nzira dzekuparadzanisa giravhiti kubvisa tsvina nekuvandudza kunaka kwesimbi.Beneficiation inogona zvakare kusanganisira kutenderera, uko makemikari anowedzerwa kune ore kuita kuti simbi zvidimbu zviyangare uye zviparadzanise kubva kune zvimwe zvese.
Pelletizing kana Sintering
Kana simbi ichinge yabatsirikana, zvingave zvakakodzera kuunganidza zvidimbu zvakanaka kuti zvive zvihombe kuti zvigadziriswe zvakanaka.Pelletizing inosanganisira kuumba diki spherical pellets nekudonha ore nezvinowedzerwa zvakaita seraimestone, bentonite, kana dolomite.Sintering, kune rumwe rutivi, inosanganisira kudziyisa maore efaindi pamwe chete nekuyerera uye mhepo yecoke kuumba semi-fused mass inozivikanwa se sinter.Aya maitiro anogadzirira ore yedanho rekupedzisira rekuchera nekuvandudza maitiro ayo emuviri uye maitiro ekubata.
Kunyunguduka
Nhanho yekupedzisira mukuita kwekuchera ndeyekunyunguduka, uko ore yesimbi inopisa muchoto chinoputika pamwe chete necoke (a carbonaceous fuel) uye limestone (iyo inoshanda semhepo).Kupisa kukuru kunoputsa simbi musimbi yakanyungudutswa, iyo inounganidza pasi pechoto, uye slag, iyo inoyangarara pamusoro uye inobviswa.Simbi yakanyungudutswa inozokandwa mumhando dzakasiyana-siyana, senge ingots kana mabhiriti, uye yozogadziriswazve kuti iwane simbi inodiwa uye zvigadzirwa zvesimbi.
Izvo zvakakosha kuti uzive kuti akasiyana iron ore deposits uye magadzirirwo emiti anogona kuve nekusiyana mune chaiwo maitiro anoshandiswa, asi iyo yose nheyo dzinoramba dzakafanana.Kubviswa kwesimbi kubva kune ore inzira yakaoma uye yakawanda-nhanho inoda kungwarira kutonga kwezvinhu uye tekinoroji.Kuiswa kwemidziyo yepamusoro senge Huate magnet separator inowedzera kushanda uye kunaka kwekuparadzanisa, kuve nechokwadi chekuti chigadzirwa chekupedzisira chinosangana nezvinodiwa zvekugadzirwa kwesimbi nesimbi.
