Mu dziko lalikulu, muli mtundu wa chuma, chavala zofiira, chobisika, ndi hematite! Chofiira chonga moto, ngati kuti chinali chokongola kwambiri m'chilengedwe, chikachiyandikira, mudzapeza kuti kukongola kwake kuli koposa pamenepo.
Chiyambi
Hematite chemical composition ya Fe2O3, ndi hexagonal crystal system ya oxide minerals, makhiristo amodzi nthawi zambiri amakhala ngati rhombic komanso ngati mbale, ma aggregate amapanga mitundu yosiyanasiyana ya flaky, granular, oolitic, reniform, earthy, scaly, dense block ndi zina zotero. Mtundu wake ndi wofiira bulauni, chitsulo imvi mpaka chitsulo wakuda, etc., mikwingwirima ndi yofiira, yachitsulo mpaka theka-chitsulo kuwala.
Hematite ili ndi mitundu yosiyanasiyana, malinga ndi mitundu yawo yosiyanasiyana komanso momwe ilili, ili ndi mayina osiyanasiyana: makhiristo a imvi opepuka otchedwa mirror iron ore, mica hematite yofanana ndi scale, loose earthy yotchedwa ocher, ma agglomerates ambiri ozungulira otchedwa renal iron ore, fibrous otchedwa pennant iron ore ndi zina zotero.
Ma hematite deposits ndi ofala kwambiri, ndipo ma hematite deposits odziwika kwambiri amapangidwa ndi sedimentation. Hematite ili ndi chitsulo chofika 70% ndipo ili ndi malo osungira ambiri, zomwe zimapangitsa kuti ikhale chinthu chofunikira kwambiri popanga zitsulo.
Kugwiritsa ntchito
1. Zipangizo zazikulu zopangira chitsulo ndi zitsulo, zomwe zimagwiritsidwa ntchito kwambiri poyendetsa, kumanga, mipando, mafakitale ndi zina, ndiye maziko a chitukuko cha mafakitale ndi chitukuko cha anthu.
2. Mtundu wa utoto wachilengedwe wa mchere, ndi utoto wofiira woyamba kugwiritsidwa ntchito kale, mtundu wake wofiira ndi woyera komanso wokhalitsa, umagwiritsidwa ntchito kwambiri pojambula, zojambulajambula ndi zina.
3. Ikhoza kupangidwa kukhala zodzikongoletsera, nthawi zambiri imakhala yofiira kapena yofiira bulauni, yokhala ndi kuuma kwambiri, ndipo imatha kupangidwa kukhala zodzikongoletsera kudzera mu kudula, kupukuta ndi njira zina zokonzera.
4. Hematite ikhoza kupangidwa kukhala njerwa za hematite ikakonzedwa. Njerwa za hematite zili ndi mphamvu zabwino zotetezera kutentha komanso zoteteza kutentha, ndipo zimagwiritsidwa ntchito kwambiri popanga zida ndi uvuni wotentha kwambiri m'gawo lamagetsi.
5. Kuwonjezera pa ntchito zomwe zili pamwambapa, hematite ingagwiritsidwenso ntchito ngati mankhwala, zowonjezera zokongoletsa, zodzaza zinthu zapulasitiki, ufa wa radium flash ndi zina zotero.
Njira Zopindulitsa
Hematite ndi mtundu wa miyala yachitsulo yopanda mphamvu ya maginito, njira zophikira zomwe zimagwiritsidwa ntchito ndi zambiri, kuphatikizapo kusankhanso, kuyandama, kulekanitsa kwamphamvu kwa maginito, kulekanitsa kwa maginito kokazinga ndi njira yolumikizirana ya njira zingapo. Pakadali pano, pali njira zitatu zophikira za hematite: kugayidwa kosalekeza - kufooka kwa maginito - kulimba kwa maginito, kugayidwa kwa magawo - kuuma ndi kuuma bwino - kugawanso maginito ndi kugawanso kwa magawo - kuuma ndi kuuma bwino. Kulekanitsa kwa maginito - kusankhidwanso, ngati kalasi yokhazikika siyili pamlingo wabwino, njira yosinthira ya anionic ingagwiritsidwe ntchito kukonza zinthu.
Kupatukana Kosalekeza kwa Magnetic-Kupatukana Kofooka kwa Magnetic-Njira Yamphamvu Yopatukana kwa Magnetic
Njirayi imadziwika ndi:
◆ Ili ndi kuthekera kosinthasintha bwino ndi momwe mineral imagwirira ntchito ngati miyala yachitsulo. Pofuna kuti miyala yachitsulo yolumikizidwa bwino imafunika kupukutidwa bwino, miyalayo imapukutidwa mosalekeza mpaka monomer italekanitsidwa, kenako kulekanitsidwa kumachitika.
◆ Kugwiritsa ntchito pamodzi mphamvu ya maginito yofooka ndi yamphamvu kumakwaniritsa njira yabwino kwambiri yogwiritsira ntchito. Pambuyo popukutira mosalekeza, njira yofooka yolekanitsa maginito imagwiritsidwa ntchito posankha zinthu zoyenera kuchokera ku magnetite yokhala ndi mphamvu ya maginito, ndipo zinthu zomwe zili mkati mwake zimasankhidwa ndi njira yolimba yolekanitsa maginito kuti zisankhe mchere wa iron oxide wofooka pogwiritsa ntchito mphamvu ya maginito, ndipo zinthu zambiri zomwe zili mkati mwake zimatha kutayidwa. Ngati mphamvu ya iron oxide yokwanira siipezeka, njira yosinthira maginito ingagwiritsidwe ntchito kupititsa patsogolo ubwino wa iron ore concentrate, kuti mupeze zinthu zapamwamba kwambiri.
◆Njirayi ili ndi makhalidwe abwino ogwirira ntchito, ndipo imapangitsa kuti ma index a beneficiation akhale okhazikika chifukwa cha kuchuluka kwake kwakukulu komanso kulamulira kosavuta kupanga.
