Chromite feem ntau pom yog cov khoom siv ntxhia hauv cov hlau- thiab magnesium-nplua nuj pob zeb tsis muaj zoglos yog concentrated hauv sediments tau los ntawm lawv. Nws tshwm sim raws li cov khaubncaws sab nraud povtseg nyob rau hauv ob peb igneous pob zeb uas tshwj xeeb tshaj yog nplua nuj nyob rau hauv hlau thiab magnesium. Yuav luag cov chromite ntshiab muaj nyob rau hauv cov khaubncaws sab nraud povtseg hauv cov pob zeb sedimentary.
Puas yog chromite yog pob zeb sedimentary?
Chromite yog cov ntxhia oxide uas muaj chromium, hlau, thiab oxygen (FeCr2O4). … Nws tshwm sim nyob rau hauv cov pob zeb uas yooj yim thiab ultrabasic igneous pob zeb thiab nyob rau hauv lub metamorphic thiab sedimentary pob zebuas yog tsim thaum cov pob zeb chromite-cov kabmob hloov pauv los ntawm tshav kub lossis huab cua.
Dab tsi yog cov ntxhia ntawm chromite?
Chromite, xim av xim av dub cubic ntxhia los ntawm pawg spinel, tsuas yog ore ntxhia los ntawm cov hlau chromium thiab chromium compounds tau txais Nws muaj cov tshuaj formula FeCr2O4, thiab cov ntsiab lus theoretical ntawm 32.0% FeO thiab 68.0% Cr 2 O3
Puas yog chromite yog cov ntxhia tseem ceeb?
Chromite yog tsuas yog qhov chaw lag luam ntawm chromium. Nws tshwm sim raws li cov pob zeb tseem ceeb ntawm cov pob zeb ultrabasic igneous thiab feem ntau cuam tshuam nrog peridotite, pyroxenite, dunite thiab serpentinite.
Cov ntsiab lus dab tsi ua rau chromite?
Chromite, kuj nyuaj, nws yog xim hlau, dub oxide ntxhia ntawm chromium thiab hlau (FeCr 2 O 4) uas yog qhov chaw lag luam tseem ceeb ntawm chromium. Nws yog tus tswv cuab tseem ceeb ntawm spinel series ntawm chromium oxides; Lwm qhov tshwm sim ntawm cov tswv cuab yog magnesiochromite, oxide ntawm magnesium thiab chromium (MgCr2O4).
