Iron ores yog pob zeb thiab cov ntxhia los ntawm cov hlau hlau tuaj yeem muab rho tawm nyiaj txiag. Cov ores feem ntau yog nplua nuj nyob hauv cov hlau oxides thiab sib txawv ntawm cov xim ntawm grey tsaus, ci daj, los yog ntshav liab mus rau rusty liab. Cov hlau feem ntau pom muaj nyob rau hauv daim ntawv ntawm magnetite, hematite, goethite, limonite los yog siderite.
Iron ore siv rau dab tsi?
Kev siv cov hlau ore (98%) yog ua steel. Qhov seem 2% yog siv nyob rau hauv ntau yam kev siv, xws li: hmoov hlau-rau tej yam steels, hlau nplaum, nws pib qhov chaw thiab catalysts. radioactive hlau (hlau 59)-rau tshuaj thiab raws li ib tug tracer keeb nyob rau hauv biochemical thiab metallurgical tshawb fawb.
Iron ore hu ua dab tsi?
Cov zaub mov hlau uas tam sim no siv los ua ores yog hematite, magnetite, limonite, thiab siderite; kuj, qee zaus ankerite, goethite, thiab turgite. Hematite yog cov hlau tseem ceeb tshaj plaws.
Yuav ua li cas thiaj tau hlau?
Feem ntau, hlau ore yuav pom nyob rau hauv qhov chaw siab dua thiab nyob ze cov pob zeb pob zeb thiab qhov tsua. Thaum taug kev hla thaj chaw Highlands, ua kom koj lub qhov muag qhib rau cov pob zeb dub loj, cov uas tsaus ntau dua li cov pob zeb thiab pob zeb uas koj hla dhau.
Yuav ua li cas yog hlau thiab hlau ore?
Txawm hais tias hlau pom muaj ntau, nws tsis pom nws tus kheej. Nws pom nyob rau hauv daim ntawv ntawm nws cov oxides nyob rau hauv lub underground pob zeb, cov no yog hu ua hlau ore. Cov khoom siv hlau ore muab cov hlau no los ntawm covunderground thiab lawv kho cov ore kom tau hlau ntshiab. Iron ore zoo nkaus li txawv ntawm cov hlau ntshiab.
