Iron ore yog ib yam mineral substance uas, thaum rhuab nyob rau hauv lub xub ntiag ntawm ib tug reductant, yuav yield metallic hlau (Fe). Nws yuav luag ib txwm muaj cov hlau oxides, thawj cov ntaub ntawv uas yog magnetite (Fe 3O4) thiab hematite (Fe 2O3). Hlau ore yog lub hauv paus ntawm cov hlau tseem ceeb rau lub ntiaj teb kev lag luam hlau thiab hlau.
Puas yog hlau ore yog pob zeb?
Iron ores yog pob zeblos ntawm cov hlau hlau tuaj yeem muab rho tawm nyiaj txiag. Feem ntau cov deposits ntawm hlau ore nyob rau hauv lub ntiaj teb no muaj nyob rau hauv pob zeb hu ua banded hlau formations (BIFs). Cov no yog cov pob zeb sedimentary uas muaj alternating txheej ntawm hlau nplua nuj minerals thiab nplua-grained silica pob zeb hu ua chert.
Puas yog hlau yog ntxhia?
Iron is a ntxhia muaj nyob hauv txhua lub cell ntawm lub cev. Hlau yog suav tias yog ib qho tseem ceeb mineral vim nws xav tau los ua hemoglobin, ib feem ntawm cov ntshav.
Puas yog hlau ore yog cov khoom siv pob zeb?
John D. Jorgenson, tus kws tshaj lij cov khoom lag luam ntxhia rau US Geological Survey, tau sau cov ntaub ntawv hauv qab no hais txog hlau ore, mineral resource tseem ceebrau kev tsim cov hlau. Nyob rau hauv qhov xwm txheej, cov ntsiab lus hlau pom muaj ntau hauv cov hlau nplaum lossis hematite, ob qho tib si hlau ore minerals.
Puas yog cov ntxhia?
Ores yog cov ntsiab lus ntawm cov pob zeb hauv pob zeb uas siab txaus los muab kev lag luam rho tawm sivTag nrho cov ores yog cov ntxhia, tab sis tag nrho cov minerals tsis tas ores. … Koj xav tau cov ntxhia los ua pob zeb, tiam sis koj tsis xav tau pob zeb los ua cov pob zeb. Txhua pob zeb yog tsim los ntawm cov ntxhia.
