Iron ores ndi miyala ndi mchere zomwe zitsulo zachitsulo zimatha kuchotsedwa mwachuma.Miyala nthawi zambiri imakhala ndi iron oxides yambiri ndipo imakhala yosiyana mitundu kuchokera ku imvi, chikasu chowala, kapena pepo wakuya mpaka kufiyira kochita dzimbiri.Chitsulo nthawi zambiri chimapezeka mu mawonekedwe a magnetite (Fe3O4, 72.4% Fe), hematite (Fe2O3, 69.9% Fe), goethite (FeO (OH), 62.9% Fe), limonite (FeO (OH)·n(H2O), 55% Fe) kapena siderite (FeCO3, 48.2% Fe).
Ores okhala ndi hematite kapena maginito ochuluka kwambiri (oposa 60% yachitsulo) amadziwika kuti "ore zachilengedwe" kapena "ore otumiza mwachindunji", kutanthauza kuti amatha kudyetsedwa m'ng'anjo zophulika zachitsulo.Iron ore ndi zinthu zomwe zimagwiritsidwa ntchito popanga chitsulo cha nkhumba, chomwe ndi chimodzi mwazinthu zazikulu zopangira chitsulo.-98% ya chitsulo chopangidwa ndi migodi imagwiritsidwa ntchito popanga chitsulo.
Phukusi la Thumba la FIBC la ores.
Zozungulira - Mtundu uwu wa thumba umapangidwa pa loom ngati chubu ndipo ndi muyezo wotsika kwambiri wa FIBC.Sidzasunga mawonekedwe ake ikapakidwa ndipo imakhala pansi ndikutuluka pakati.Zidzafanana ndi phwetekere pamene zimanyamulidwa, monga mankhwalawo adzatambasula nsaluyo pamene akukhudzidwa ndi kukakamizidwa kwa mankhwala omwe akunyamulidwa.
U-Panel - Chikwama cha U-panel ndi sitepe yochokera ku thumba lozungulira, popeza lidzakhala ndi zidutswa ziwiri za nsalu zofanana ndi U mawonekedwe omwe amasokedwa pamodzi kuti apange mawonekedwe a thumba.Idzasunga mawonekedwe ake a square bwino kuposa mawonekedwe ozungulira.
Four-Panel - Chikwama chamagulu anayi ndi thumba labwino kwambiri lokhala ndi masikweya kuposa thumba la baffle.Zimapangidwa ndi zidutswa zinayi za nsalu zomwe zimapanga m'mbali ndi imodzi ya pansi.Zonsezi zimasokedwa pamodzi zomwe zimatsutsana ndi zizolowezi zotambasula za thumba ndikuzisunga mu cube mawonekedwe bwino kwambiri.
Baffle - Mtundu uwu udzakhala wabwino kwambiri pakusunga mawonekedwe a cube ya chinthu chanu chikwama chikadzaza.Ili ndi ma baffles owonjezera omwe amasokedwa pansi pakona iliyonse kuti akhale ngati thumba kuti mudzaze ngodya iliyonse.Kuphatikiza apo, pali matumba ena osokedwa mbali zonse kuti zinthu zonse zizisonkhana mozungulira ma baffles ndi matumba.Izi ndi zabwino ngati muli ndi kachidutswa kakang'ono kakang'ono monga soya yemwe amatha kudutsa m'miyendo popanda kupachikidwa.Matumba ochulukawa adzakhala osavuta kuunjika chifukwa apanga lalikulu lalikulu cube.
